Question

Hearing with two ears is called binaural hearing.

Research results show that people, who wear two hearing devices regularly, do understand language and conversations better than those, who only wear one hearing device. Within acoustic challenging situations, language can definitely be better understood with two hearing devices rather than one. In company you can better localise from which direction someone is talking to you. Regarding road traffic you can better determine from which direction a vehicle may approach, thereby improving your safety. When turning-on your hi-fi sound system, you have the best sound quality when both loudspeakers are connected; the same with hearing devices. Your acoustic range will be extended from 180 degree to 360 degree. This all around hearing gives you good sound balance and sound quality. 

In the end, binaural hearing can be compared with wearing glasses - nowadays no one wears a monocle! Therefore, wearing two hearing aids in stead of one is certainly recommend. 

Another important advantags is that both ears stay active. When a bilaterally hearing impaired person wears a hearing aid on only one ear, the ability of the unused ear decreases to hear and understand.
