The Max-30 MAX provides a NRR 30 dB noise reduction profile when worn correctly, attenuating the peak noise exposure from equipment operation, impact tools, and material handling to levels below OSHA's 8-hour average exposure limit of 90 dBA. For workers operating near particularly loud equipment — compressors, pneumatic tools, chippers — the Max-30 provides the attenuation margin that keeps daily noise dose within safe exposure parameters.\u003c\/p\u003e\n\n\u003cp\u003eProper earplug insertion is the critical performance variable for disposable foam hearing protection. The foam formula of the Max-30 is engineered to compress to a diameter small enough for insertion with rolled-down technique while providing sufficient recovery speed to expand and fill the ear canal within 30–60 seconds of insertion. A properly inserted earplug seals against the ear canal walls along the full contact length of the plug — this circumferential seal is what produces the rated NRR attenuation. Incomplete insertion, where only the tip enters the canal, produces substantially lower attenuation than rated and is the most common cause of noise dose overexposure despite \"wearing\" hearing protection.\u003c\/p\u003e\n\n\u003cp\u003eThe retention cord connects the two earplugs and provides a practical tethering function for worksites where earplugs are frequently removed and reinserted as workers move between noisy and communication areas. The cord prevents individual earplug loss during removal — earplug loss in a hearing protection program represents both a cost and a compliance gap as workers in noisy areas may defer inserting new plugs rather than returning to a supply station. The cord also allows the plugs to rest around the neck during communication-required tasks without requiring full removal and storage.\u003c\/p\u003e\n\n\u003cp\u003eThe disposable design of the Max-30 supports the single-use hygiene standard that OSHA's hearing conservation program and most industrial health programs require. Reused foam earplugs accumulate earwax, sweat residue, and particulate contamination that degrades foam density, reduces compliance with ear canal geometry, and poses contamination risk in pharmaceutical, food processing, and cleanroom environments. Single-use distribution with adequate supply density at work area access points ensures workers can always access clean hearing protection without behavioral friction.\u003c\/p\u003e\n\n\u003ch2\u003eApplications and Use Cases\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eManufacturing — equipment operators, assembly line workers in high-noise production environments\u003c\/li\u003e\n  \u003cli\u003eConstruction — pneumatic tool, compressor, and heavy equipment noise exposure management\u003c\/li\u003e\n  \u003cli\u003eWoodworking and finishing — router, planer, and belt sander noise attenuation\u003c\/li\u003e\n  \u003cli\u003eMetal fabrication — grinding, cutting, and press operations exceeding 85 dB TWA\u003c\/li\u003e\n  \u003cli\u003eMining and resource extraction — continuous high-noise environment hearing protection\u003c\/li\u003e\n  \u003cli\u003eAviation ground support — jet engine and turbine noise environments requiring high-attenuation protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%;\"\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eMax-30\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProduct ID\u003c\/td\u003e\n\u003ctd\u003e8707661987928\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDisposable Foam Earplug\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNRR\u003c\/td\u003e\n\u003ctd\u003e30 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCord\u003c\/td\u003e\n\u003ctd\u003eCorded\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eSlow-Recovery Polyurethane Foam\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompliance\u003c\/td\u003e\n\u003ctd\u003eANSI S3.19, NIOSH Listed\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoward Leight\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUse\u003c\/td\u003e\n\u003ctd\u003eSingle-Use Disposable\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSold As\u003c\/td\u003e\n\u003ctd\u003eBox (multiple pairs)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/hearing-protection\"\u003eHearing Protection — Full Collection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/safety-glasses\"\u003eSafety Glasses — Eye Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/disposable-respirators\"\u003eRespirators — Respiratory Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eWork Gloves — Hand Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/hard-hats\"\u003eHard Hats — Head Protection\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdl\u003e\n  \u003cdt\u003eWhat does NRR 30 mean?\u003c\/dt\u003e\n  \u003cdd\u003eLaboratory-rated noise reduction of 30 dB under ideal fit conditions.
