49% of under 35s have hearing issues

A 2023 study found that 49% of under 35s have "less than normal hearing," with a quarter experiencing hearing loss and two in five having "probable" hearing loss. The "speech-in-noise" test revealed difficulties in hearing speech in noisy environments and identifying sound direction. Unsafe listening and urban noise are cited as causes. Following the 60/60 rule (listening at 60% volume for no more than 60 minutes) is recommended to prevent further damage.
