The acoustic otoscope utilizes Spectral Gradient Acoustic Reflectometry to measure middle ear effusion in seconds.

​

Spectral Gradient Acoustic Reflectometry (SGAR) is a technology that uses sound waves to detect middle ear fluid.

​

The acoustic otoscope is the only device that utilizes spectral gradient acoustic reflectometry to measure middle ear effusion.

Unlike a tympanometer, the acoustic otoscope can be used in the smallest infant or an adult, does not cause any pain with use, does not require the patient to remain completely still, and can provide diagnostic results in a few seconds.
