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.
The risk of negative health effects from sound exposures (be it noise or music) is primarily determined by the intensity of the sound , duration of the event, and frequency of that exposure. [9] These three factors characterize the overall sound energy level that reaches a person's ears and can be used to calculate a noise dose.
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 ...
The loops carry baseband audio-frequency currents; no carrier signal is used. The benefit is that it allows the sound source of interest – whether a musical performance or a ticket taker's side of the conversation – to be transmitted to the hearing-impaired listener clearly and free of other distracting noise in the environment. [6]
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 ...
