Hearing Quiz with Candice

Take our hearing quiz and see how much you know about your hearing.

Q: All Living creatures use ears to hear: True or false?

A: False

Not all living creatures hear with ears. Snakes use jawbones, fish respond to pressure changes, and male mosquitoes use antennae.

Q: The smallest bone in our body is found in…

A. The foot

B. The ear

C. The hand

D. The nose

A: B, the ear.

Q: An untreated hearing loss increases your likelihood of developing Dementia or Alzheimer’s disease:

A: True

B: False

A: A

Individuals with an untreated hearing loss are 30% more likely to suffer from Alzheimer’s or Dementia. This is due to a lack of stimulation of the auditory cortex in the brain. When an individual has a hearing loss sound does not reach our auditory cortex which causes this area to shrink increasing your likelihood of developing Dementia or Alzheimer’s.

Q: True or false:

The best way to clean your ears is with an ear/cotton bud.

A: False
When using ear buds we stop our ears natural cleaning process. The ear is able to clean itself by moving the wax to the outer portion of the ear where it eventually falls out. When one uses ear buds we push the wax into the deeper portion of the ear canal where it cannot clean itself. The only way you should clean your ears is with a wet cloth at the entrance to the ear canal. Certain individuals will struggle with a chronic wax buildup and in these cases it needs to be syringed out by your doctor or audiologist.

Q: The function or purpose of ear wax is to:

A: Keep our ears lubricated

B: Trap dust, dirt and foreign objects

C: Protect our ears from bacteria and fungi

D: Prevent bugs and insects from crawling into the ear canal

A: All of the above

Ear wax or cerumen is the ears self-cleaning mechanism. It traps dust and dirt that enters the ear canal, protecting the ear drum. The wax then moves to the entrance of the ear canal cleaning out the dirt or any foreign bodies. Individuals with no ear wax or those who clean their ears too often suffer from dry and itchy ear canals. Most importantly wax prevents bugs from crawling into our ears at night.

Q: True or false: Exposure to the sound of a vuvuzela causes permanent, non-reversible hearing loss.

A: True

Our cochlea is made up of millions of hair cells. These hairs are responsible for hearing. Exposure to sound levels above 80 decibels can cause these hair cells to become damaged. The sound of a vuvuzela averages 131 decibels at the horn opening and 113 decibels at a 2 meter distance. This means the hair cells of the cochlea become damaged with each blow causing permanent hearing loss.
