Overall, binaural listening is more comfortable, natural and effective

There are many reasons to use two hearing instruments (a “binaural” fit) instead of one. The most fundamental reason is that you have two ears.

Your brain is accustomed to processing sound from both sides of your head. It’s no wonder, then, that balancing the loudness of sounds entering both your ears works better than using just one ear.

Test comparisons show that people with hearing instrument in both ears can distinguish words better than those with one instrument, and hear sounds from a greater distance. They also have a much greater ability to tell which direction sounds are coming from.

Furthermore, using just one instrument creates a “head shadow effect,” in which sounds lose their intensity by having to go around a person’s head to the amplified ear.
