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.

AEC100 NBS 9A 6 cc Coupler for 1
inch microphone
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. |

Simulator
A new Ear
Simulator for testing a variety of earphones using the latest standards
AEC201-A is a new ear simulator designed to be used with both
supra-aural and circumaural earphone at frequencies up to 16000 Hz. Its
design meets the requirements of IEC 60318-1:2009 Edition 2 and ANSI
S3.7 section 5.4 which make it compatible with earphones like TDH 39,
TDH 49, TDH 50, HDA200 and Koss HV/1A. The AEC201-A is supplied with
the 377A13 microphone and a Type 1 adapter plate. |

AMC493B Artificial Mastoid
Use
this innovative transducer for bone vibrator testing
The
AMC493B is cost effective and simple to use. Its patented design
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..
