MODEL AUDCAL AUDIOMETER CALIBRATION SYSTEM TYPICAL APPLICATIONS ■ Audiometer calibration Booth qualification for ambient noise Speaker testing PORTABLE, APP-CONTROLLED CALIBRATION The SoundAdvisor™ Audiometer Calibration System AudCal is a field-ready solution for fast, comprehensive audiometer calibration. The system combines the power and versatility of the SoundAdvisor Model 831C sound level meter with the accessibility and functionality of the LD G4 Utility Software. AudCal works seamlessly with a tablet for both testing and data collection–no PC is required. Artificial ear couplers and mastoids are available to simplify the challenge of interfacing with a wide variety of audiometer transducers. Whether you are performing a typical audiometric test, a booth qualification for ambient noise, or a speaker test, Larson Davis is here to simplify your measurement challenges. AudCal creates a complete, portable audiometer test and calibration solution. Access the meter on a PC or through the app on your mobile device to setup and run the full suite of tests with ease. Measurement capabilities include frequency, hearing level, FM, and pulse. Narrowband FFT and real time 1/3 octave analysis make measurements such as total harmonic distortion (THD) and ambient noise easy and accurate. After completing the test suite, generate a test report and certificate that details the pass/fail, and parameters of each test. Test reports can be exported as a PDF that can be printed, shared, and saved.

SIMPLIFYING YOUR TESTING When you need to test and measure an audiometer’s performance to ensure accurate test results, Larson Davis is ready to support you with a fully inclusive Audiometer Calibration System. AudCal Systems deliver a complete package of hardware, firmware, and software designed to streamline your testing.
