According to World Health Organization, more than one billion young adults are at risk of permanent hearing loss due to unsafe listening practices. Likewise, 25% of adults over 60 have significant hearing loss, so getting a hearing test is probably a good idea. The test itself requires no preparation and will usually have you listening to various sounds through headphones (via WebMD).
Sounds will be low and high, short and long, loud and quiet, and will ring out in each ear individually. There may also be a test that involves listening to the sound of people speaking and repeating the words you hear. The test will take around 30 minutes and shouldn’t be painful or scary as the sounds are played at levels to test you, without causing any damage.
Results will be reviewed based on the level of hearing loss. An average adult has a hearing loss of up to 25 decibels. Decibels are the unit of measurement for sound, with normal speech occurring at around 60 decibels. A hearing loss of 26 to 40 decibels is considered mild, 41 to 55 decibels is moderate, 56 to 70 decibels is moderate to severe, 71 to 90 decibels is severe, and 91 to 100 decibels is profound. Although hearing loss cannot be cured, it can be managed. Johns Hopkins Medicine advises that preventing hearing loss through earplugs and avoiding loud noises is the best way to protect your hearing as you age.
