Abstract
A hand-held, battery-driven, oto-acoustic emission analyzer has a measuring probe, introduceable into the patient's ear, having a first acoustic generator and an acoustic detector. An electronic circuit is connected to the first acoustic generator to generate first oto-acoustic stimulus signals transmitted by the first acoustic generator and connected to the acoustic detector to measure and process oto-acoustic emission signals received by the acoustic detector. A display is coupled to display data processed by the electronic circuit. A housing holds the electronic circuit and the display, the housing being adapted to be held in a user's hand.
