The Reason Behind having Two Ears

Did you ever wonder why we have two ears? It’s not just to follow the symmetrical pattern of the rest of our body. 

Having two ears that both function properly is called “binaural hearing”. Our ears are designed to harness sounds from our environment. If you have ever experienced, or if you currently experience, hearing loss in one ear, you understand the difficulty of hearing noises or knowing which direction they are coming from without another ear to hear them. Hearing aid users might also observe a difference while only wearing one hearing aid.

Directional Sounds

Ears transfer sound waves to the brain, which is where the sound gets interpreted. A working ear on each side of the head makes it easier to figure out where sounds are emanating from. This is known as “sound localization”, or “directional hearing”.    

An Extensive Range of Hearing
 
Two ears that can hear lets you hear sounds clearer from each direction. Only being able to hear sounds out of one ear is limiting to the other side of the head. The range of hearing becomes restricted for noises, and it makes them harder to understand.

When you socialize with other people, it’s easier to hear what others are saying with two ears. Struggling or feeling frustrated from not being able to hear others creates anxiety and listening fatigue. One healthy ear can hear up to 180 degrees, whereas two healthy ears can hear up to 360 degrees.

Improved Quality of Sound 

You’ve probably experienced a few moments when just one stereo speaker or one earbud/headphone created sound. It had a poor sound quality that wasn’t loud or clear enough. This is basically what happens with your ears. Two ears provide a more balanced and natural sound. Only hearing with one ear feels odd because your brain is not receiving equal stimulation. 

A Buffer Zone for Loud Noises

Two ears essentially create a buffer zone that allows sound to become divided among the two ears. Louder noises become easier to tolerate. Binaural hearing saves our hearing health by letting sudden, loud noises become less intense by dividing it between the ears. 

Hearing out of both ears is important for your overall quality of life and significantly helps with daily responsibilities.
