WHAT? This kind of hear­ing loss in­volves dam­age to the hair cells within the in­ner ear (cochlea), or the hear­ing nerve. It can be caused by get­ting older and by ex­po­sure to loud noises, as well as com­pli­ca­tions at birth, in­fec­tion, or be­cause of cer­tain genes. One to two ba­bies in ev­ery 1,000 are born with per­ma­nent hear­ing loss in one or both ears.

SYMP­TOMS? This kind of hear­ing loss af­fects the abil­ity to hear qui­eter sounds, but also the qual­ity of the sound, mak­ing it dif­fi­cult for the per­son af­fected to un­der­stand speech.

TREAT­MENT? Sen­sorineu­ral hear­ing loss is a per­ma­nent con­di­tion, and hear­ing aids are of­ten needed. These con­sist of a mi­cro­phone, an am­pli­fier, a built-in loud­speaker and a bat­tery. They act to in­crease the vol­ume of sound en­ter­ing the ears.
