e3 Diagnostics

Audiologists use tympanometry measurements to test the middle ear's mobility when changes in air pressure occur. Recorded on a graph called a tympanogram, the results of tympanometry tests offer information about air pressure in the middle ear. Middle-ear tympanometry helps audiologists diagnose hearing loss and recommend a solution such as a hearing aid.

From handheld tympanometers to desktop models that offer a complete range of middle ear tests, e3 Diagnostics has the tools you need. Our tympanometry devices will allow you to diagnose patients' hearing issues so they can improve their quality of life quickly. You can feel confident with our high-quality tympanometry equipment from respected manufacturers including MAICO, Interacoustics, Amplivox, and Grason-Stadler.
