The auditory (hearing) neurons can change in structure, function and resource allocation.The hearing system is very complex and involves connections to many other areas of the brain, as well as different types of neurons. Researchers suggest that hearing loss can affect non-auditory areas of the brain as well as the auditory system.Our brains are amazing! When we are not hearing well the brain redirects some of...

What is tympanometry?

Tympanometry is a test that measures the movement of the eardrum in response to changes in air pressure. It is commonly used to evaluate the function of the middle ear and diagnose conditions such as middle ear infections and eustachian tube dysfunction. Here are the different types of tympanograms:Type A: A normal tympanogram with a peak in the middle of the graph indicates normal middle ear function. The pressure at which the peak occurs is called the "tympanometric peak pressure" and should b...
