Humans are born with two ears.
But why isn’t one ear enough?

Nature has intended for us to hear with two ears, known as binaural hearing. Binaural hearing allows us to locate sounds, focus on conversations in noisy settings, and listen closely for longer without getting exhausted.

When You Can’t Hear with Two Ears

When one ear suffers, a person’s quality of life also suffers. Those suffering from hearing loss in one ear typically notice the following changes in everyday life:

  • Social or work conversations in noisy places are hard to follow.
  • It is difficult to tell where sounds come from.
  • More mental effort is needed to listen, leading to fatigue.
  • Being in noisy places often causes anxiety.

A Simulation:
Hearing Loss in One Ear

It is often difficult for friends, coworkers and family members to understand how someone with hearing loss in one ear experiences everyday situations differently. We have created two short clips comparing full binaural hearing to hearing loss in one ear.

To compare the difference, put on headphones. Make sure that left and right are on the correct sides. Next, choose a scene and press play to start. As you listen, holding the mouse button will simulate hearing with two ears and releasing the mouse button will simulate hearing with one ear. Notice the difference, then click the arrow on the left or right to switch scenes.

“After asking someone to repeat what they said three or four times during a conversation, I gave up! I retreated into myself and stopped actively participating in conversations.”

Johanna Pätzhold, age 24

Thousands Have Overcome Hearing Loss

Those suffering from hearing loss are not alone. Although hearing loss can be overwhelming, thousands all around the world have overcome this challenge.

Over 466 million people worldwide suffer from disabling hearing loss.1

Adults who report hearing loss are 6.5% more likely to suffer moderate to severe depression.2

Approximately one third of people over 65 years of age are affected by disabling hearing loss.1
