Hearing Aids
Hearing Aid Test with APx500 Audio Analyzers
Hearing aids are truly unique from an audio test perspective. They are one of the few audio devices that have both acoustic input and acoustic output, and even the simplest ones have microphones, a power amplifier, digital signal processor, loudspeaker and controls integrated into a tiny, battery-powered package.
AP’s reliable and high-quality audio analyzers deliver production test ROI with reduced test times, simple automation and are perfectly suited for R&D to the production line. AP also meets both domestic and international industry standards—IEC 60118-0, and ANSI/ASA S3.22.
“We implemented the APx511 across multiple production lines in several countries and are seeing huge savings in test time and ease of integration within our software development environment.”- Carl Blackwood, manager, Test & Configuration Systems, Unitron (Sonova Group Worldwide)
