2.Adikasyon tande tande vibrasyon son k ap antre nan zòrèy la. Selil cheve siviv detekte vibrasyon yo pi gwo ak konvèti yo nan siyal neral ke yo pase ansanm nan sèvo a. Pi gwo domaj nan selil cheve yon moun, pi grav nan pèt tande a, ak pi gwo a anplifikasyon èd tande a bezwen fè diferans lan. Sepandan, gen limit pratik nan kantite anplifikasyon yon èd tande ka bay. Anplis de sa, si zòrèy enteryè a twò domaje, menm gwo vibrasyon pa pral konvèti nan siyal nè. Nan sitiyasyon sa a, yon èd odyans ta efikas.

2.A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.
