The Larson Davis SoundAdvisor Audiometer Calibration System Model 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. 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.
