Hearing Testing

A hearing (audiometric) test is part of an ear examination that evaluates a person's ability to hear by measuring the ability of sound to reach the brain.
The sounds we hear start as vibrations of air, fluid, and solid materials in our environment. The vibrations produce sound waves, which vibrate at a certain speed (frequency) and have a certain height (amplitude). The vibration speed of a sound wave determines how high or low a sound is (pitch). The height of the sound wave determines how loud the sound is (volume).
Hearing happens when these sound waves travel through the ear and are turned into nerve impulses. These nerve impulses are sent to the brain, which "hears" them.
It is very important for people of all ages to get their hearing tested periodically. 
If you think you are having trouble hearing it would be a good idea to at least take an online hearing test.

The best place to go for hearing aids in Houston is the Center for Audiology.
