A hearing protection device, also known as a HPD, is an ear protection device worn in or over the ears while exposed to hazardous noise and provide hearing protection to help prevent noise-induced hearing loss. HPDs reduce the level of the noise entering the ear.
While some consider the noise reduction of a suppressor significant enough to permit safe shooting without hearing protection ("hearing safe"), noise-induced hearing loss may occur at 85 time-weighted-average decibels or above if exposed for a prolonged period, [67] and suppressed gunshots regularly meter above 130 dB.
Hearing protection in musicians offers its own sets of benefits and complications. When used properly, hearing protection can limit the exposure of noise in individuals. Musicians have the ability to choose from several different types of hearing protection, from conventional ear plugs to custom or high fidelity hearing protection.
Using both ear muffs (whether passive or active) and earplugs simultaneously results in maximum protection, but the efficacy of such combined protection relative to preventing permanent ear damage is inconclusive, with evidence indicating that a combined noise reduction ratio (NRR) of only 36 dB (C-weighted) is the maximum possible using ear ...

The human ear can typically stand a sound pressure level of 120 dB before feeling pain. AHDs are capable of 135 dB or more of acoustic energy. OSHA states that any sound pressure level over 90 dB requires hearing protection. [16] As volume increases so does the chance of hearing loss.
