Floriogra 6-Pack Electronic Ear Muffs — SNR 34 dB, Bulk

What the NRR on the box is, and is not

The Noise Reduction Rating is a labelling requirement, not a performance promise. It is mandated by the EPA under 40 CFR Part 211, Subpart B and derived from laboratory testing to ANSI S3.19, on trained subjects under ideal fit conditions.

Attenuation achieved in the field is materially lower, which both regulators acknowledge. OSHA 1910.95 Appendix B converts the rating for A-weighted measurement by subtracting 7, and OSHA separately recommends halving the result as a safety factor; NIOSH derates formable foam by 50%. At or above an eight-hour TWA of 85 dBA the employer owes a full hearing conservation program — audiometric testing, training and protector choice — not simply a rated product.

Frequently asked questions

What is the Floriogra 6-Pack?

A bulk set of six identical electronic ear muffs rated SNR 34 dB, with electronic compression of loud sounds and ambient amplification for speech clarity. It is designed for shooting ranges, training facilities, and supervisors equipping multiple people at once.

What does SNR 34 dB mean?

SNR is the Single Number Rating, the European measure of hearing-protector attenuation - it is not the same as the US ANSI NRR used for OSHA compliance. Confirm the equivalent NRR on the product page if you need it for a US hearing conservation program.

Is SNR the same as NRR?

No - they are different rating systems from different standards, and the numbers are not directly interchangeable. SNR generally reads higher than the NRR for the same product, so do not treat SNR 34 as an NRR 34.

How does the electronic function work?

Built-in microphones sample ambient sound continuously; audio below a threshold, typically 82 to 85 dB, passes through to the internal speaker so you keep awareness of speech, while louder sounds are compressed to protect your hearing.

Does the amplification add protection?

No - amplification is for situational awareness and speech clarity, not extra noise reduction. Your protection comes from the muff's passive attenuation; the electronics manage which sounds reach your ears.

Why a 6-pack?

The bulk format lowers the per-unit cost and equips multiple people at once - a range loaner fleet, a firearms class, or a shift crew - without repeated single-unit purchasing. All six units are identical in specification.

What work is it for?

Shooting ranges, firearms training, and small-crew or visitor outfitting where several people need electronic hearing protection at once and situational awareness matters between loud events.

How much real-world protection is that?

Like any lab-derived rating, real-world attenuation is lower than the SNR figure once fit and seal are factored in. Fit each muff properly, confirm the equivalent NRR for your program, and double with plugs in the loudest settings.

What powers them?

Batteries power the electronics; keep spares on hand. If a unit's batteries die, it still provides its passive attenuation - you lose the amplification, not the hearing protection.

Can I double up with ear plugs?

Yes - wearing plugs under a muff adds protection for louder environments, though the combined rating is not simply the two added together. Add plugs when measured noise exceeds what the muff covers.

When should I replace them?

Replace a unit when the cushions harden or lose their seal, when the electronics fail, or after any damage, and change batteries when the amplification weakens - a muff that no longer seals no longer protects.

How do I order for a crew?

The six-pack already suits crews, and larger quantity purchasing runs through a free Amazon Business account - volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations. The walkthrough is linked in our footer.
