WebMany young adults engage in loud activities, which can cause noise-induced hearing loss (NIHL). 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 …
