What are the common causes of hearing loss in adults?

Some of the most common causes of hearing loss include:

  • Aging
  • Excessive noise exposure
  • Injury
  • Viral infections (such as measles or mumps)
  • Wax buildup
  • Ototoxic drugs (medications that damage hearing)
  • Genetics

Hearing loss can occur at any time during your lifespan. No matter the cause of your hearing loss, you can benefit from getting your hearing checked by a hearing care specialist.

Step 1 of 5

Age-related hearing loss (presbycusis)

Age is a very common cause of hearing loss. It is caused by changes in the inner ear that occur as you grow older. Additionally, genes and loud noise can also play a big role. When your hearing starts to weaken, it becomes more difficult to:

  • Hear soft voices
  • Hear high-frequency sounds (voices of children and women)
  • Follow conversations in the presence of background noise.

Because the loss is gradual, you may not realize that you’ve lost some of your ability to hear.

Noise-induced hearing loss

Repeated exposure to high levels of noise is another common cause of hearing loss. If you are exposed to loud noise for too long, the sensitive hair cells in the inner ear become damaged, and your ability to hear clearly can be compromised.

Some people have a higher risk of developing noise-induced hearing loss when they are regularly exposed to loud noise. Listening to excessively loud music at live concerts (or through headphones) can be another cause of hearing damage.

Congenital hearing loss

Congenital hearing loss means that a baby is born with a hearing problem. The baby's hearing loss can be caused by a number of factors including genetic defects, infections during pregnancy or low birth weight.

When compared to all causes of hearing loss, congenital hearing loss is quite rare: about 1% of babies are born with hearing loss1.

Protect your ears in loud environments

It is very important to protect your ears in these situations by limiting exposure to loud sounds (when possible) or by wearing high-quality and well fitted ear plugs or earmuffs.

2. Impact of noise exposure 
Can cause permanent hearing loss and depends on how loud it is and how long you are exposed without a break

3. Live music
Noise damage can occur anywhere, for example concerts or festivals where the sound levels are very high, especially if your ears ring afterwards

Did you know?

Today’s hearing aids are more technologically advanced and smaller than ever.

Some hearing aids can be virtually invisible and yet offer excellent sound quality - even in difficult listening situations.

Others can also be connected to your smartphone (or other smart devices) in order to stream sound directly to your hearing aids.

Options for dealing with hearing loss

Fortunately, there is help available regardless of the cause of your hearing loss. Understanding the source of your issues gives our hearing care experts insight into your needs.


While there is a wide range of possible causes and treatments for hearing loss, many cases of hearing loss can be assisted by hearing aids. Your hearing care expert can explain the best options for you after you have completed a hearing test.
