Portible Audiometer Calibration System

The new 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.

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.
