Hearing loss in one ear occurs when you cannot hear or you have deafness that affects only one of your ears. 


Hearing Loss in one ear is a condition that occurs due to the significant or completely hearing loss in one ear.

This problem is also known as Single Sided Deafness or SSD.  If you have this problem then you cannot understand speech in noisy environment, locating the source of a sound, and tuning out background noise.  This condition is called as unilateral hearing loss or unilateral deafness. But you should still be able to hear clearly with your other ear.

In the case of SSD you can prefer the hearing aid. This Hearing Aid transmits the sound from the deaf ear to a hearing aid in your better ear.

CROS Hearing Aids are used as the solution of SSD. This Hearing Aids picks up the sound from your deaf side and transmit it to your better ear. With the help of this hearing aid you can hear the sound on your deaf side.

This hearing aid is helpful when you are in the challenging environments such as a noisy room, in a moving car or  in a group discussion.
