For all types of hearing protection, OSHA's derating factor is 50%. If used with C-weighted noise, the derated NRR will become NRR/2. [41] If used with A-weighted noise, OSHA applies the 7-dB adjustment for C-A weighting first then derates the remainder. [41] For example, a protector with 33-dB attenuation would have this derating:
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.
Modern over-the-ear headphones offer incredible sound and impressive noise-cancelling, often for a surprisingly low price. (Photos: 1More, Soundcore, Sony)
Ear protection, if used correctly, can reduce noise to safer levels, but often, providing them is not sufficient to prevent hearing loss. Engineering noise out and other solutions such as proper maintenance of equipment can lead to noise reduction, but further field studies on resulting noise exposures following such interventions are needed.
