The Headphone Production Test Fixture Model AEC210 is a cost effective solution for production volume headphone testing on a production line. Flush-mounted microphones and the flexibility to add speakers and additional microphones make it possible to test both noise-cancelling headphones and headsets with microphones. Two fully adjustable headphone positioners allow for accurately controlled placement and consistent, repeatable testing. A modular mounting system allows the positioning of additional microphones and speakers in the same location every time for increased testing consistency and quality systems compliance. The Headphone Production Test Fixture is an excellent alternative to costly head and torso simulators or devices using IEC 60318-4 compliant couplers.
An optional speaker, Model AEC210-SPK, can be added to the Headphone Production Test Fixture for testing noise cancelation and be used as an artificial mouth to test integrated headset microphones. For measuring noise outside of the headphones with microphones positioned at critical measurement locations, fully adjustable microphone stands are available as an option. The modular design allows for countless mounting configurations of multiple speakers and additional microphones.
