Walker's GWP-SLR Silencer Electronic Ear Muffs Review (2026)
Situational Awareness Without Sacrificing Protection: Do the Walker's Silencer Ear Muffs Deliver?
Walker's GWP-SLR Silencer Electronic Ear Muffs Review (2026)
Electronic ear muffs occupy a specific and valuable niche in hearing protection: they let you hear the world around you — conversation, range commands, approaching hazards — while automatically blocking the impulse noise that damages hearing. Walker's Game Ear has built a large portion of their lineup around this concept, and the Silencer series sits squarely at the center of that lineup. The GWP-SLR Silencer Electronic Ear Muffs carry an NRR of 23 dB under ANSI S3.19 and are positioned for shooters, hunters, and industrial workers who need OSHA-compliant protection without being cut off from their environment.
This review covers what the specs actually mean — not just the marketing copy — and where these muffs fit inside the broader landscape of electronic ear muffs. All performance claims below are grounded in the product page, ANSI S3.19 test standards, and OSHA 29 CFR 1910.95 derating methodology. We do not fabricate specs, amplification figures, or user testimonials.
The bottom line up front: at $129.94, the Walker's Silencer is a mid-range electronic earmuff with a solid NRR 23 dB rating and genuine impulse-suppression electronics. It serves shooters and hunters well. Industrial buyers in continuous-noise environments above 98 dBA TWA will need to evaluate double protection or a higher-NRR device. Read on for the full breakdown.
Editorial Verdict: 4.2 / 5
A well-rounded electronic earmuff for shooting sports and hunting, with verified NRR 23 dB protection and automatic impulse suppression. OSHA-compliant for workplaces up to ~98 dBA TWA. Not the highest NRR available, but the electronic awareness feature sets it apart from passive alternatives at the same protection level.

Cons
- NRR 23 dB limits use to environments up to ~98 dBA TWA — not rated for the loudest industrial settings
- Electronic earmuffs add weight and complexity vs. passive muffs at equivalent NRR
- Over-ear form factor less compact than in-ear electronic options
- Designed primarily for shooting/hunting — industrial 8-hour shift endurance not specified
Who the Walker's Silencer Is For
The Walker's GWP-SLR Silencer is primarily designed for:
- Sport shooters and range users who need to hear range commands between strings of fire
- Hunters who need to detect game movement and still be protected at the shot
- Law enforcement and tactical trainers requiring situational awareness during live-fire exercises
- Industrial workers in environments up to ~98 dBA TWA where communication is also required
- Safety managers building out a hearing protection program that balances protection with operational awareness
If your environment exceeds 98 dBA TWA, OSHA 29 CFR 1910.95 requires a protector that, after derating, reduces exposure to below 90 dBA. At NRR 23, the Silencer provides approximately 8 dB of derated attenuation (OSHA method: subtract 7, divide by 2), which covers environments up to 98 dBA TWA. Above that threshold, double protection or a higher-NRR device is required. See our guide to understanding NRR ratings for the full calculation methodology.
Strengths: Where the Walker's Silencer Performs
1. Verified NRR 23 dB — ANSI S3.19 Certified
The NRR on the Walker's Silencer is not a marketing claim — it is a laboratory-tested rating under ANSI S3.19, the American National Standard for the Measurement of Real-Ear Attenuation at Threshold. This test protocol requires panel testing on human subjects with a fitting and removal protocol. The resulting NRR of 23 dB establishes the device's outer boundary of noise reduction under ideal fit conditions. Under OSHA's required 50% derating (subtract 7, divide by 2), the real-world figure is approximately 8 dB. Under NIOSH's recommended 50% derating of the full NRR, the figure is approximately 11.5 dB. Either way, these are not passive muffs — their NRR is identical whether electronics are on or off, because the physical cup provides the attenuation. The electronics determine what you hear, not how much noise gets in. This is a critical distinction that separates electronic earmuffs from passive ones: you are not trading protection for awareness.
2. Automatic Impulse Suppression Above ~82 dB
The defining feature of any electronic earmuff is its impulse suppression circuit. The Silencer compresses or cuts the speaker output when ambient sound exceeds approximately 82 dB — the threshold broadly recognized as the boundary of hearing-safe continuous exposure. When a gunshot, explosive report, or impact tool fires at 140–165 dB peak SPL, the electronics react in milliseconds to prevent that peak from being reproduced through the speaker at damaging levels. The NRR 23 passive cup provides the remaining attenuation against any residual impulse energy that bypasses the compression circuit. The 82 dB threshold means the amplification is also bounded: ambient sounds are amplified up to that ceiling and no higher, preventing the device from becoming an inadvertent hearing hazard in continuously loud environments. This is the same architecture used across the electronic earmuff category — see our best hearing protection guide for a full comparison of electronic muff architectures.
3. Ambient Sound Amplification — Operational Awareness Retained
The external microphones pick up environmental sound and route it through the internal speakers at amplified volume — enabling the wearer to hear normal conversation, range commands, and low-level cues they would miss with passive muffs. This feature is not unique to the Walker's Silencer, but it is the primary reason electronic muffs command a premium over passive alternatives. For shooting sports, hunting, and any task requiring communication while working in a hazardous noise environment, this is the feature that determines whether protection gets worn consistently. A protector that gets removed to communicate is a protector that is not protecting. Browse our shooting hearing protection collection to see how the Silencer compares with other electronic options across the NRR and price spectrum.
4. Rechargeable Battery Design (GWP-SLCR2-BT Variant)
The specific variant stocked here is the GWP-SLCR2-BT, which features a rechargeable battery design. This eliminates the ongoing cost and environmental waste of disposable batteries — a meaningful advantage for users who wear electronic muffs regularly. The passive NRR 23 protection remains available even when the battery is fully depleted, since the cup construction provides physical attenuation regardless of power state. For range-use patterns (hours per session, sessions per week), a rechargeable design typically delivers a meaningfully lower total cost of ownership versus a comparable device running disposable cells.
5. OSHA 29 CFR 1910.95 Compliance for Workplaces Up to ~98 dBA TWA
OSHA's Hearing Conservation Standard (29 CFR 1910.95) requires employers to implement a hearing conservation program when employee noise exposure reaches or exceeds the action level of 85 dBA TWA (8-hour time-weighted average). At the permissible exposure limit of 90 dBA TWA, a hearing protector rated NRR 23 — when derated per OSHA's formula — reduces effective exposure to approximately 82 dBA, comfortably below both thresholds. At 98 dBA TWA, the derated reduction brings effective exposure to approximately 90 dBA — right at the PEL. Environments at or above 98 dBA TWA require a higher-NRR device or double protection. For facilities building or reviewing a hearing conservation program, the Walker's Silencer is a viable protector in the mid-noise-level tier.
Weaknesses: Where the Walker's Silencer Has Limits
1. NRR 23 dB Caps Effective Attenuation at ~98 dBA TWA
The NRR 23 is a solid, mid-range rating — but it is not the highest available in earmuffs, which can reach NRR 30–33 dB. For consistent industrial use in environments above 98 dBA TWA, the Walker's Silencer cannot independently bring exposure below OSHA's 90 dBA PEL. Heavy manufacturing, certain construction operations, and high-caliber indoor shooting ranges may exceed this threshold, requiring either double protection (muffs over plugs, which adds approximately 5 dB to the higher-rated device's effective NRR) or a higher-NRR muff. Our guide to best earplugs for work covers the double-protection calculation in detail.
2. Over-Ear Form Factor Adds Bulk vs. In-Ear Alternatives
Electronic over-ear muffs are inherently larger and heavier than in-ear electronic alternatives. For hunters moving through terrain, shooters who need to mount a rifle without cup interference, or users who simply prefer a lower-profile solution, the over-ear form factor is a genuine constraint. The best in-ear hearing protection for shooting guide covers electronic in-ear options that trade NRR rating for compactness — a real trade-off that deserves evaluation for your specific use case.
3. Not Specified for 8-Hour Industrial Shift Endurance
The Walker's Silencer is designed and marketed for shooting sports and hunting — sessions measured in hours, not 8-hour industrial shifts. While the NRR is compliant with OSHA standards, the device is not specifically validated for continuous industrial wear. Battery life, clamping force comfort over an 8-hour shift, and sweat resistance under sustained use are not specified for industrial conditions. Industrial users considering electronic muffs for shift-length wear should evaluate the full ear muffs collection including models with industrial-specific ratings and ergonomics.
4. Higher Unit Cost vs. Passive Alternatives at the Same NRR
The electronic amplification and impulse-suppression circuitry adds cost relative to a passive muff at NRR 23. If situational awareness is not a requirement for your application — steady-state industrial noise, low-communication environments — a passive muff at the same NRR will protect equally well at a lower purchase price. The electronic feature set only delivers value when the ambient sound amplification is actively needed. Evaluate whether your use case justifies the premium before selecting.

Walker's Silencer Series: Which Variant Is Right for You?
Walker's Game Ear produces the Silencer in several configurations within the GWP-SLR product family. The key decision points within the series are:
- GWP-SLR (Standard): Core Silencer muff — electronic amplification, impulse suppression, NRR 23 dB, disposable battery power
- GWP-SLCR2-BT (Rechargeable Bluetooth): The variant carried here — adds rechargeable battery and Bluetooth audio streaming
Decision rule: If you shoot or hunt regularly and want to eliminate battery replacement cost, the rechargeable Bluetooth variant is the better long-run choice. If you primarily need basic electronic protection without wireless audio, the standard configuration is simpler and typically lower cost.
Compatible Accessories
Electronic earmuffs can be paired with additional PPE without compromising protection, provided fit seals are maintained. Consider:
- Earplugs (double protection): For environments above 98 dBA TWA, insert foam or corded earplugs under the Silencer muffs. OSHA double-protection guidance: use the higher of the two NRR values, then add 5 dB
- Face shields / safety glasses: Temple arms of glasses can disrupt the cup seal on over-ear muffs, reducing effective attenuation. If wearing safety glasses with the Silencer, verify the seal is maintained and consider low-profile temple arm frames. Browse our full PPE collection
- Hard hat compatibility: Not all over-ear muffs mount to hard hat slots. Verify compatibility with your hat model before purchasing for construction or industrial use. Hard-hat-mount electronic muffs are a separate product category
OSHA and ANSI S3.19 Standards Context
Understanding what the NRR actually means — and how regulators expect you to apply it — is essential for compliance decisions. ANSI S3.19 is the test standard; the NRR on the label is the result of that lab test. OSHA 29 CFR 1910.95 Appendix B specifies how employers must derate that number for real-world application: subtract 7 from the NRR, then divide by 2.
For the Walker's Silencer (NRR 23): (23 - 7) / 2 = 8 dB effective attenuation. This means the device is appropriate for workplaces where noise exposure does not exceed 90 dBA + 8 dB = 98 dBA TWA.
NIOSH recommends a more conservative 50% derating of the full NRR: 23 x 0.50 = 11.5 dB. This approach yields a slightly higher effective attenuation than the OSHA method but remains conservative relative to laboratory conditions.
For electronic earmuffs specifically, ANSI S3.19 measures attenuation of the physical cup — not the electronic circuit. The NRR applies in passive mode (electronics off or battery dead) and does not change when the device is in active amplification mode, because the cup structure is what provides the acoustic seal. The electronics determine speaker output level, not the amount of outside noise blocked by the cup. This is why electronic muffs with identical NRR to passive muffs provide equivalent protection: the active circuitry routes amplified ambient sound through the speaker at a controlled, hearing-safe level rather than letting outside sound penetrate the cup directly.
For a complete walkthrough of NRR methodology, derating calculations, and how to select the right protector for your measured noise levels, see our NRR hearing protection guide and our full hearing conservation program guide.
Total Cost of Ownership
Electronic earmuffs have a higher unit cost than passive alternatives, but the TCO calculation depends on use pattern:
- Purchase price: $129.94 for the GWP-SLCR2-BT rechargeable variant
- Battery cost: Rechargeable design eliminates ongoing disposable battery purchases — relevant for regular range or hunting use
- Replacement: Electronic muffs require replacement if the circuit fails; passive muffs can be rebuilt with replacement cushions. Cushion replacement is the most common maintenance item on any over-ear muff and extends usable life significantly
- Comparison baseline: A passive muff at NRR 23 with no electronics will protect equally in steady-state noise environments. The electronic premium purchases the ambient awareness feature only — not additional attenuation
For occasional shooters who do not need situational awareness, a passive muff at the same NRR will deliver equivalent protection at lower cost. For anyone who fires multiple rounds in a session and needs to hear range commands, the Walker's Silencer's electronic feature set is a meaningful operational improvement — and the rechargeable design reduces the battery cost gap over time.
Final Verdict
The Walker's GWP-SLR Silencer Electronic Ear Muffs earn a 4.2 out of 5 for their combination of verified NRR 23 dB protection, genuine impulse suppression at the ~82 dB threshold, and ambient sound amplification that makes the muffs operationally practical for shooting sports and hunting. The rechargeable GWP-SLCR2-BT variant reduces ongoing battery cost. The NRR 23 limits application to environments up to ~98 dBA TWA, and the over-ear format is not the most compact option available — but within its design envelope, the Silencer delivers what it promises: hearing protection that does not cut you off from your environment.
For shooters who wear their muffs often and need to hear between shots, this is a strong choice at the mid-range price point. For industrial applications at or above 98 dBA TWA, evaluate double protection or higher-NRR options from our ear muffs collection.

Frequently Asked Questions — Walker's GWP-SLR Silencer Electronic Ear Muffs
What is the NRR of the Walker's Silencer Electronic Ear Muffs?
The Walker's GWP-SLR Silencer has an NRR of 23 dB, certified under ANSI S3.19. Using OSHA's required derating formula (subtract 7, divide by 2), the effective real-world attenuation is approximately 8 dB. Using NIOSH's 50% derating, the figure is approximately 11.5 dB. At NRR 23, these muffs are appropriate for environments up to approximately 98 dBA TWA.
Does the Walker's Silencer protect against gunshots?
Yes. The Silencer's electronics react in milliseconds to compress or cut the speaker output when impulse noise (gunshots, impacts) exceeds approximately 82 dB, preventing the amplified signal from reaching damaging levels. The NRR 23 passive cup provides additional physical attenuation. This combination is specifically designed for impulse-noise environments such as shooting ranges, hunting, and tactical training.
Can you hear conversation while wearing the Walker's Silencer?
Yes. The Silencer amplifies ambient sounds through internal speakers, allowing the wearer to hear normal conversation, range commands, and environmental cues. The amplified output is capped at approximately 82 dB — above which the suppression circuit activates — so the device does not create a hearing hazard from amplified ambient sound in moderate-noise environments.
What is the difference between the GWP-SLR and the GWP-SLCR2-BT?
The GWP-SLR is the base Silencer model. The GWP-SLCR2-BT is the rechargeable Bluetooth variant of the Silencer series — it adds a rechargeable battery (eliminating the need for disposable cells) and Bluetooth audio capability. Both share the NRR 23 dB rating and core impulse-suppression electronics. The variant stocked on this page is the GWP-SLCR2-BT.
Are the Walker's Silencer muffs OSHA compliant?
Yes. The Walker's Silencer meets ANSI S3.19 and is an accepted hearing protector under OSHA 29 CFR 1910.95. Using OSHA's derating formula, the effective attenuation is approximately 8 dB. The muffs are compliant for workplaces up to approximately 98 dBA TWA. Above that level, a higher-NRR device or double protection is required.
Do the Walker's Silencer muffs work if the battery dies?
Yes. The NRR 23 passive attenuation is provided by the physical cup construction, not the electronics. If the battery is depleted or the device is powered off, the muffs continue to block noise at NRR 23 — they simply function as passive earmuffs. There is no reduction in protective capacity from a dead battery; the only loss is the ambient sound amplification and impulse suppression features.
What is the maximum noise level the Walker's Silencer can be used in?
Using OSHA's derating formula (NRR 23 minus 7, divided by 2 = 8 dB effective attenuation), the Walker's Silencer is appropriate for environments up to approximately 98 dBA TWA to comply with OSHA's 90 dBA PEL. Above 98 dBA TWA, double protection (earplugs under muffs) or a higher-NRR device is required. Consult your facility's noise survey data and safety program before selecting hearing protectors for industrial use.
Can the Walker's Silencer be used with safety glasses or a face shield?
Safety glasses can be worn with over-ear muffs, but the temple arms may create a gap in the cup seal, reducing effective attenuation. To minimize this effect, use low-profile temple arm frames. Face shields that mount to a hard hat rather than resting against the head generally interfere less with muff seal than side-mounted shields. Browse our PPE collection for compatible face protection options.
How does the Walker's Silencer compare to the Howard Leight Impact Sport?
Both are mid-range electronic earmuffs with ambient sound amplification and impulse suppression. The Howard Leight Impact Sport has an NRR of 22 dB vs. NRR 23 for the Silencer — a 1 dB difference that is not practically significant. Key differentiators are form factor, battery type, and brand ecosystem. The Walker's Silencer rechargeable variant eliminates battery purchases; the Howard Leight is widely available with a Bluetooth variant. Try both if possible; comfort and fit seal are the most important real-world attenuation factors.
Is NRR 23 sufficient for indoor shooting ranges?
NRR 23 is commonly used at indoor ranges, but the adequacy depends on your specific range noise levels and how many rounds you fire per session. Indoor ranges can generate significant reverberant noise from multiple shooters, potentially driving effective TWA above 98 dBA. If you shoot in high-volume indoor range environments, consider NRR 25–33 passive muffs or double protection (foam earplugs under the Silencer) for additional margin. Our best hearing protection guide includes an indoor range use case section.
What does "ambient sound amplification" mean on electronic earmuffs?
External microphones pick up environmental sound and route it through internal speakers at a controlled amplified volume — typically louder than unaided hearing for low-level sounds, but always capped at approximately 82 dB. This allows normal conversation to be heard clearly while wearing muffs that would otherwise block all sound. When a loud impulse (gunshot) is detected, the circuit suppresses the speaker output to prevent damage. The result: you hear the world, but not the gunshots at damaging levels.
Can the Walker's Silencer be used for hunting?
Yes. Electronic muffs are popular with hunters specifically because the ambient amplification enhances detection of game movement and environmental sounds in the field, while the impulse suppression protects hearing at the shot. The over-ear form factor is slightly bulkier than in-ear alternatives — see our best in-ear hearing protection for shooting guide for compact alternatives if low profile is a priority for your hunting application.
What is the ANSI S3.19 test standard?
ANSI S3.19 is the American National Standard for the Measurement of Real-Ear Attenuation at Threshold for hearing protectors. Manufacturers test their devices on a panel of human subjects under a specified fitting protocol. The resulting data produces the Noise Reduction Rating (NRR), which represents the laboratory-measured protective capacity of the device. OSHA's regulations require that the stated NRR be derated before it is applied to exposure calculations, because real-world fit conditions differ from the controlled laboratory test.
How do I calculate whether these muffs are adequate for my noise level?
Use the OSHA derating formula: take the NRR (23), subtract 7, divide by 2. The result (8 dB) is the effective attenuation. Subtract this from your measured or estimated noise level (in dBA TWA) to determine your residual exposure. If the result is below 90 dBA (OSHA PEL) or 85 dBA (OSHA action level), the device is adequate. At 95 dBA TWA, residual = 95 - 8 = 87 dBA — below the PEL. At 100 dBA TWA, residual = 100 - 8 = 92 dBA — above the PEL, requiring additional protection. See our NRR hearing protection guide for worked examples.
Are there workplace regulations that require electronic earmuffs specifically?
No. OSHA 29 CFR 1910.95 requires that hearing protectors reduce exposure to within the permissible limits but does not mandate electronic earmuffs specifically. Electronic earmuffs are chosen for operational reasons — situational awareness, communication — not regulatory mandate. The regulatory requirement is met by any ANSI S3.19 certified device with an adequate derated NRR for the measured noise exposure.
