What Hearing Aids Cannot Do

Hearing aids can’t

• grow new hair cells
• restore the normal function of a damaged hearing system

Humans are born with 15,500 hair cells in each cochlea. Hair cells detect sound and transfer the signal to the brain.

Human damaged hearing cells can not regenerate themselves the same as our damaged teeth do not regrow back.

Only birds and amphibians can regenerate hair cells throughout their lives.⁸

• make speech sound B/P, T/D, K/G, F/V, S/Z. more distinct

Prevent or improve hearing loss from the organic condition make speech sound B/P, T/D, K/G, F/V, S/Z. More distinct hearing loss can be compared to vision loss in person has damaged or scratched the retina of their eye. The dead area of the retina makes holes in their visual field. These holes stay the same with or without glasses. The dead-area of damaged hearing cells makes a dead area in the frequency regions of hearing. If outer hearing cells are damaged, you won’t be able to hear the difference between sounds b/p, d/t, f/v etc. with or without hearing aids.⁷
