Audiometric Testing and Calibration Devices and Methods

摘要

An audiometric testing device is provided including a housing having one or more integral calibration couplers adapted to couple with a testing transducer. The testing device also includes a tone generator that generates tones of various frequencies and intensities during a hearing test. A calibration transducer is positioned proximate the coupler and converts an output of the testing transducer into a calibration signal. The calibration signal is measured by a signal measurement module within the housing, which generates a calibration measurement that can then be used to correct for undesired intensity level variations produced by the tone generator. Audiometric testing systems and calibration methods are also provided. In some cases a testing and/or calibration of an audiometric testing device is controlled by an external computing device coupled to the testing device.
