What is it indicated for?
The SmartOAE device is intended to be used for the purpose of determining the distortion
product response of the human cochlea. The device is intended to be used by hearing health
professionals to determine cochlear function. The test administered by the device does not
require any patient behavioral response, such as pushing a button switch. The device delivers
sound signals into the outer ear and subsequently records the sound in the outer ear which
contain sounds produced by normal cochleas. The device also measures the level of sound
near the distortion product frequency to estimate the noise level present while the test was
performed.
