The audio analyzer designed specifically for the needs of hearing instrument manufacturers.
The APx511 Hearing Instrument Audio Analyzer is designed to meet the needs of hearing instrument manufacturers, providing the specific measurements and I/O required for hearing instrument production test, delivered with Audio Precision’s reputation for high performance and reliability.
All APx models use the same software, so with the R&D department using an APx525 or APx585 and APx511 deployed on production lines, product design is faster, interaction between Engineering and Production is easy and the AP report generated by Quality Control is trusted around the world.
APx511 supports a .NET library of functions that automate the tests described in IEC60118- 7 and ANSI S3.22. For the production environment, these functions can be called from any .NET capable language or LabVIEW to control the APx511’s output and measurement settings.
For troubleshooting or test setup, the APx511 can be controlled by the standard APx500 software providing a rich graphical user interface and access to automated reporting, real-time signal monitors, high resolution FFTs and controls for limits & other settings.
In addition to standard audio tests such as level, distortion, frequency response, and attack & release, APx511 can measure battery current using its built-in battery simulator circuit.
The APx511 generator includes an in-line 2 watt loudspeaker amplifier (8 ohms) and a telecoil amplifier, allowing >110 dB SPL and up to 400 mA/m field strength from 100 Hz to 10 kHz in a test chamber such as the Interacoustics TBS25. On the input side, APx511 supplies 24 V DC of constant current through a single BNC for a pre-polarized measurement microphone.
All audio & power connections are located on the back of the instrument in line with production test standard practices. The microphone input is a standard BNC connector. The outputs connect via a standard DB-15 connector to reduce cabling errors in the production environment. A DB-15 break-out cable terminating in the required connectors for specific test chambers is provided with each APx511.
