If you find yourself frustrated with your ability to hear, you are certainly not alone.&nbsp;As an individual loses the ability to hear, less sounds will be picked up by the ear and understood by the brain. The degrees of hearing loss ranges between slight, mild, moderate, moderately severe, severe, and profound. Normal hearing ranges between -10 \u2013 15 decibels (dB). The following graph displays the degrees of hearing loss by decibels of hearing lost (dB HL).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"690\" height=\"484\" src=\"https:\/\/hearingindustry.ca\/wp-content\/uploads\/2021\/11\/degrees-of-hearing-loss.png\" alt=\"\" class=\"wp-image-443\" srcset=\"https:\/\/hearingindustry.ca\/wp-content\/uploads\/2021\/11\/degrees-of-hearing-loss.png 690w, https:\/\/hearingindustry.ca\/wp-content\/uploads\/2021\/11\/degrees-of-hearing-loss-300x210.png 300w\" sizes=\"auto, (max-width: 690px) 100vw, 690px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How hearing works Hearing is a complex process where many fragile parts of the ear work together to relay signals to the brain.
