Model AudCal for Certification and Testing
The new SoundAdvisor Audiometer Calibration System Model AudCal from Larson Davis is a complete, portable, field-ready solution for fast, comprehensive audiometer testing and 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.

Artificial mastoid coupler and additional weight ring. This innovative transducer for bone vibrator testing is a precision mechanical coupler used to calibrate bone conduction hearing aids and audiometer bone vibrators. It provides a simple to use design that converts the vibrator force output to an acoustic signal measured with the system’s sound level meter. It is used with the AEC100 coupler or AEC201-A Ear Simulator to perform bone vibrator tests. Compliant with standards ANSI S3.13-1981(R2007) and IEC 60318-6: 2007.
