Audio Precision announces the APx511 audio analyser that is designed for the needs of hearing instrument manufacturers. It is a low cost, high speed production test audio analyser with a 24VDC constant current supply for pre-polarized measurement microphones and an in-line 2W loudspeaker amplifier and telecoil amplifier.

The analyser is said to be the first customised model with all the required inputs and outputs plus automated test routines for the ANSI and IEC standards required by the R&D departments of hearing instrument companies.

The APx511 can run all the tests described in the IEC60118-7 and ANSI S3.22 standards that define hearing instrument tests for Europe and America, respectively. 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. 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.
