Audiometer Calibration Software


A comprehensive line of couplers, systems and software! Larson Davis audiometer calibration systems combine the speed and power of the System 824 real time analyzer with the sophisticated, yet user-friendly, AUDit software. Standard audiometer specification tests can be performed manually or under computer control with greater ease than with any other system. To interface with the large variety of audiometer transducers, the Larson Davis family of couplers includes NBS 9-A and IEC 318 couplers as well as an extremely practical artificial mastoid. Finally, there is a rugged, portable solution for in-house or in-field audiometer calibration which sacrifices none of the accuracy and stability of laboratory instrumentation.
