Binocular vision allows us to accurately identify the direction and avoid danger. The same binaural hearing can also fully protect us, because binaural listening can play the role of accurate positioning of the sound source. Hearing experts recommend hearing-impaired people as long as there are hearing impairments in both ears, and in the absence of other contraindications, be sure to choose a hearing aid with both ears to obtain a higher quality listening experience.

1, accurate positioning of sound

The ear wearer hears the sound of the car behind, but can’t judge which side the car is coming from. This is a very dangerous thing, and the hearing aids can accurately locate the direction and position of the sound source.

2, protecting residual hearing

Wearing only one ear will overly rely on the side ear of the hearing aid. The other side of the ear will not be exercised for a long time, and the residual hearing will be gradually lost. This is the phenomenon of “hearing deprivation” in medicine.

3, easier to hear the words

Binaural wear eliminates the “head shadow effect”, reduces the head’s obstruction to high-frequency sounds, and makes it easier to hear and distinguish the content of speech.

4, listening to whispers is easier

It is more laborious for a single ear wearer to listen to a small voice, and the binaural accumulation can increase the total loudness of the sound, making it easier to listen to the whisper.

5, easier to hear in noisy environments

The natural “squeaking effect” of the ears is used to suppress the background noise and improve the signal-to-noise ratio. As shown in the figure below, in a quiet environment, the speech intelligibility of a single ear wearing a hearing aid and a hearing aid with both ears is not much different, and is slightly lower than that of a normal hearing person. In a noisy environment, the speech intelligibility of the hearing aids of both ears is close to that of normal hearing people, and the hearing comfort of the hearing aids of the single ear is lower.

6, more stereo sound

Listening to both ears produces a stereo effect, and the speech you hear is more natural and the music is more beautiful.
