Calculate the … WebA Signal-to-noise ratio is a measure of the amount of background noise with respect to the primary input signal. It is formally defined as he ratio of signal power to noise power, and is often expressed in decibels. For example, a ratio of 1:1 indicates more signal than noise, and is greater than 0 decibels (dB).

Some studies suggest that NIHL and age-related hearing loss (ARHL) lead to relatively rapid shifts in the hearing threshold level (HTL) of the extended high frequency (EHF) range (> 8 kHz). It has been hypothesised that NIHL may first present with HTL …
