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. Despite this, use of hearing protection among musicians is low for several different reasons.
Hearing protector fit-testing is a method that measures the degree of noise reduction obtained from an individual wearing a particular hearing protection device (HPD) - for example, a noise canceling earplug or earmuff. Fit testing is necessary due to the fact that noise attenuation varies across individuals.
Low frequency noise is attenuated worse than mid- and high-frequency noise. Most employers did not have the means to measure the noise spectrum. It was assumed that the average noise attenuation in workplaces is about the same as in laboratory conditions. It was believed that the differences in noise attenuation among different workers are small.
Loop’s highest decibel earplug is the Loop Quiet; if you’re looking for something stronger with better noise reduction, consider Mack’s soft foam earplugs $10, which have 33 decibels SNR or ...
Such custom molded earplugs with low pass filter and mechanical valve typically have a +85 dB(A) mechanical clamp, in addition to having a lowpass filter response, thereby providing typically 30-31 dB attenuation to loud impulse noises, with only a 21 dB reduction under low noise conditions across the human voice audible frequency range (300 ...
Thus, in situations where noise is dominated by low-frequency energy, earplugs are likely to be more effective. Earmuffs also fail to provide any noise reduction at infrasonic frequencies (< 20 Hz), [ 20 ] which is energy that cannot be heard because it falls below the range of human hearing sensitivity.
