[how to listen to the two ears?] the human brain is great and mysterious. When there is a sound coming from the outside world, a unique binaural processing will take place in the brain. According to the information obtained, such as time, intensity, phase, frequency, etc., use the ear that receives the sound signal in a better position or extract the effective sound information from the binaural signal difference to eliminate the noise, so as to carry out a The same side or opposite side signal processing can obtain clear stereo listening. Therefore, binaural listening is helpful to increase the activity of auditory pathways in both sides of the brain, while unilateral listening can easily lead to the phenomenon of “hearing deprivation” in medicine because it only stimulates one side.

Avoid single ear hearing fatigue: in noisy environment, double ears have better comfort than single ear listening. When using hearing aids, you can keep the volume low, but you can get a clearer and louder sound.

Tinnitus masking effect: research shows that about 50% of users wear hearing aids, tinnitus has relief.

Anti squealing ability enhancement: when hearing aid users use two ears, the required gain will be lower than that of single ear, so the probability of hearing aid squealing will be greatly reduced.
