While some people have sudden hearing loss, the majority of people lose their hearing gradually over time. It can be a bit tricky to know when you need hearing aids because hearing loss varies from person to person.
These different sounds range from 0 dB (the average sound a person can hear with normal hearing) to 140 dB (the threshold of pain). A decibel chart shows the intensity levels of environmental sounds you commonly hear around the house, at work, in school, and in other places. The degree of hearing loss is determined by the ability to hear certain frequencies (Hz) at each level of hearing loss, which is measured in decibels (dB). Have you been wondering how much hearing loss you need to have before requiring a hearing aid?
