Audiometer Calibration Audiometer Calibration Certification and Electro-acoustic Test Systems Applications n Audiometer certification Audiometer testing Earphones and hearing aid testing Electro-acoustic testing Universities and Research Programs Workplace Hearing Conservation Programs Full line of artificial ear couplers and accessories including new AEC201-A, IEC 60318-1:2009 Ear Simulator and AMC493B Artificial Mastoid Portable, Rugged and Accurate Verify audiometers quickly and accurately using ANSI S3.6-2004 Specification for Audiometers Test virtually every type of transducer such as supra-aural, extended range circumaural, bone vibrator, hearing aid, insert earphone, and speaker Automatically correct the RETSPLs for microphone, coupler, and all other response adjustments using AUDit™ software Larson Davis audiometer calibration systems combine the power and versatility of the System 824 real time analyzer 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 analyzer and precision SLM Perform level and frequency adjustments during audiometer tests Level, frequency, FM, and pulse measurements are only some of the capabilities of the System 824 real time analyzer when fitted with 824-AUD firmware. Qualify audiometric booth ambient noise with real time 1/3 octave analysis and fast pass/fail results (MPANL) Narrow-band FFT and real time 1/3 octave analysis make measurements such as THD and ambient noise easy and accurate. Store and recall tests in databases; query databases by audiometer, technician, date, etc. Print custom reports and certificates for your clients or your archives 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. Larson Davis

Audiometer Calibration An integration of SLM/OBA analyzer, software and couplers for fast, comprehensive in-clinic testing or field calibration of Audiometers The 824-AUD Firmware provides audiometer testing The System 824 comes standard with real time fractional octave filters necessary for audiometer tests. The 824-AUD firmware adds additional features such as FM and pulse, plus a powerful 400-line FFT for narrow-band analysis and total harmonic distortion. Real time analysis for HL, frequency & THD Hearing level measurements are simple using the real time 1/3 octaves of the displays...

Audiometer Calibration Test Accessories A rugged artificial ear for testing supra-aural earphones The AEC100 Coupler is a precision acoustic coupler designed primarily for the calibration and test of supra-aural earphones used in audiometry. It allows accurate and repeatable measurements within its frequency response (up to 8 kHz). It may also be used for production testing where correlation between the coupler and real ear response is not a requisite. Optional Couplers for Insert Type Hearing Aids and Earphones A new Ear Simulator for testing a variety of earphones using the latest...
