The Advantages of Wearing Two Hearing Aids

Are two hearing aids better than one?

If you’re looking for the short answer, then yes, the majority of cases of hearing loss are best managed with two hearing aids.

If you want to know why, or are curious about exactly why we have two ears in the first place, then continue reading.


Let’s begin with vision.

When we look at an image, each eye acquires a slightly different version of that image. Our brains then calculate the differences between the two copies to produce the perception of depth. This added dimension of depth—coupled with height and width—helps us to experience the world in three dimensions.

If we had just one eye, our capability to perceive depth and distance would be highly affected.


The same phenomenon pertains to our ears and our hearing. Although we might not think about it, when we hear a sound, we can frequently determine both its distance and its location, in addition to its volume.

Each ear receives a slightly different version of each sound, and those differences are translated by the brain in a way that reveals location and distance. This permits us to hear in three dimensions, so that we know how far away and which direction sound is originating from.

In addition to being able to evaluate depth, distance, and location, having two ears also enhances the quality of sound and increases the range of sounds you can hear.

To check the principle of sound quality, the next time you’re playing music in the car, turn off both left speakers and notice how unnatural it sounds.


If our eye doctor tells us that we have vision impairment in both eyes, we don’t seriously consider the benefits of getting fitted with one lens.

So when our hearing specialist informs us that we have hearing loss in both ears, why do we need to be persuaded to use two hearing aids?

As we’ve seen, our ears collaborate so that our brains can best decipher the distance, location, volume, quality, and range of sound.

With the ability to establish the exact location of sound from using two hearing aids, you’ll have the ability to:

  • concentrate on speech during a conversation even with substantial background noise.
  • pick out specific voices among many.
  • increase the range of sounds heard by up to four times.
  • hear sounds without straining, which is less tiring.
  • listen to sounds without the abnormal feeling of monaural hearing (hearing with one ear).
  • Prevent the deterioration of hearing in the non-fitted ear.

That last point is important. If you have hearing loss in both ears but use only one hearing aid, your hearing in the non-fitted ear can become even worse as time passes. This will promptly restrict your ability to achieve all of the benefits just explained.

If you think you have hearing loss, the first step is to schedule a hearing test with an experienced hearing professional. After your hearing is examined, your hearing specialist will discuss the results with you in a chart known as an audiogram.

The audiogram will reveal to you if you have hearing loss in one or both ears, but most cases of hearing loss are in both ears.

If this is the case, your hearing specialist will most likely highly recommend binaural hearing aids for both ears, and you’ll be given the opportunity to try them before you buy—which is a great opportunity to assess for yourself the difference two hearing aids will make.
