Encourage a friend or family member to get their hearing tested.  Whether it's for a baseline test or a retest to monitor the stability of your current hearing status, be smart! Get your hearing tested!



Parts of the Ear: Outer Ear | Middle Ear | Inner Ear 


Hearing is one of the five senses. It is a complex process of picking up sound and attaching meaning to it. The ability to hear is critical to understanding the world around us.

The human ear is fully developed at birth and responds to sounds that are very faint as well as sounds that are very loud. Even before birth, infants respond to sound. People often comment that they hear but do not understand the words. 


So, how do we hear?

The ear can be divided into three parts leading up to the brain - the outer ear, middle ear and inner ear.

  • The outer ear consists of the ear canal and eardrum. Sound travels down the ear canal, striking the eardrum and causing it to move or vibrate.

  • The middle ear is a space behind the eardrum that contains three small bones called ossicles, the smallest bones in our body. This chain of tiny bones is connected to the eardrum at one end and to an opening to the inner ear at the other end. Vibrations from the eardrum cause the ossicles to vibrate which, in turn, creates movement of the fluid in the inner ear.

  • Movement of the fluid in the inner ear, or cochlea, causes changes in tiny structures called hair cells. This movement of the hair cells sends electric signals from the inner ear up the auditory nerve (also known as the hearing nerve) to the brain.


  • The brain then interprets these electrical signals as sound.




If you are experiencing lightheadedness, a sensation of losing your balance, or a sense  

of feeling unsteady, you may be one of the millions of Americans who experience dizziness. Dizziness is a common complaint and affects 20% to 30% of the general population. In fact, dizziness is  

a common reason that adults seek medical attention.

When your balance is impaired, you may feel unsteady, woozy, or disoriented. You may have blurred vision or experience a sensation of movement. It may seem that the room is spinning (vertigo). You may not be able to walk without staggering or you may not even be able to get up. Sometimes nausea, vomiting, diarrhea, faintness, changes in heart rate or blood pressure, fear, and also anxiety may accompany the dizziness and balance problems.

Dizziness can be associated with a variety of conditions such as:

  • Viral or bacterial infections, including ear infections
  • Foreign objects into the ear canal
  • Blood pressure changes
  • Vascular problems
  • A fistula (hole) in the inner ear
  • Ménière's disease
  • Medicines or drugs poisonous to the ear or balance system (ototoxic medicines)
  • Multiple sclerosis
  • Visual disorders
  • Tumors, especially of the vestibular portion of the eighth nerve (known as Acoustic Neuroma)
  • Head injury (traumatic brain injury,TBI)


Vertigo is a type of dizziness where there is a sense of movement or spinning. Changing position, such as sitting up in bed, can make it seem worse. Nausea and vomiting may accompany the vertigo at times. If your vertigo is positional, then possibly a canalith repositioning procedure (CRP maneuver) can be performed to lessen or eliminate your vertigo.

Parents may think that noise is a problem they need not worry about until their child reaches the teenage years. Surprisingly, some toys are so loud that they can cause hearing damage in children. Some toy sirens and squeaky rubber toys can emit sounds of 90 dB, as loud as a lawn mower. Workers would have to wear ear protection for similarly noisy sounds on the job.


The danger with noisy toys is greater than the 90-dB level implies. When held directly to the ear, as children often do, a noisy toy actually exposes the ear to as much as 120 dB of sound, the equivalent of a jet plane taking off. Noise at this level is painful and can result in permanent hearing loss.


Toys that pose a noise danger include cap guns, talking dolls, vehicles with horns and sirens, walkie-talkies, musical instruments, and toys with cranks. Parents who have normal hearing need to inspect toys for noise danger.


Before purchasing a new toy, listen to it. If the toy sounds loud, don't buy it.



Examine toys you already have at home. Remove the batteries or discard the toys if they are too noisy and pose a potential danger to hearing. Some parents place heavy duct tape over the speakers on noisy toys.
