I. Specification of headphone production testing machine AEC210

The AEC210 Headphone Production Prototype is a cost-effective solution for checking production line volume of headphones.
The flush-mount microphone and the flexibility to add additional speakers and microphones make it possible to test both noise-cancelling headphones and headsets with microphones. Two fully adjustable headphone positioners allow for precisely controlled placement and consistent, repeatable testing.
A modular mounting system allows additional microphones and speakers to be positioned in the same location at all times for increased testing consistency and quality system compliance.
The Headset Manufacturing Tester is a great alternative to expensive head and body simulators or devices that use IEC 60318-4 compliant couplers.
An optional loudspeaker, Model AEC210-SPK, can be added to the Headphone Production Tester to test noise cancellation and used as an artificial mouth to test the built-in headset microphone.
For measuring noise outside of headphones with microphones placed in critical measurement locations, a fully adjustable microphone stand is optional. Modular design allows for a multitude of installation configurations of additional speakers and microphones.
