Audiometer Calibration and Electro-acoustic Test System by Larson Davis

Larson Davis audiometer calibration systems combine the power and versatility of the System 824 real time analyser with AUDit™ software to create a complete, portable audiometer test and calibration solution. Standard audiometer tests can be performed manually on the sound level meter or automatically with AUDit™ software which controls the sound level meter to run a full battery of audiometer performance and accuracy tests. For interfacing with the wide variety of audiometer transducers used, Larson Davis offers NBS 9-A, IEC 60318 and other couplers as well as an extremely practical artificial mastoid. The combination of AUDit™ and the 824 is a field ready solution for fast, comprehensive audiometer calibration.

System 824: Electro-acoustic analyser and precision SLM

Level, frequency, FM, and pulse measurements are only some of the capabilities of the System 824 real time analyser when fitted with 824-AUD firmware. Narrow-band FFT and real time 1/3 octave analysis make measurements such as THD and ambient noise easy and accurate. AUDit™ PC Software automates the test process, walking you through the complete calibration process.

After the test procedure you can easily print pass/fail reports and calibration certificates. Data can also be exported to Microsoft® Excel.
