Tympanometers include fully clinical and diagnostic instruments, screening devices with limited testing capabilities, handheld or portable options, and combination devices that have more than one modality. The type of tympanometer used in each facility depends on the patient population and testing needs. A clinical middle ear analyzer will be the most versatile and includes a number of predefined test types such as tympanometry with multiple probe tones, Y, B, and G immittance options, reflex thresholds, reflex decay, ARLT, Multi Hz, and ETF tests (intact, patent, patulous). Diagnostic tympanometers allow for basic tympanometry and ipsilateral acoustic reflex testing and sometimes have the option to upgrade to specific special tests such as contralateral reflex testing or additional probe tones. Screening and handheld tympanometers are limited to basic testing.
