Audio Precision Unveils Binaural Headphone Test FixtureBEAVERTON, Ore., June 28, 2017 /PRNewswire/ -- Audio Precision, the recognized standard in audio test, today introduced the AECM206 Headphone Test Fixture. Headphone measurements can be complicated, owing to the close coupling of earphones to the ears and the corresponding acoustic transmission paths, as well as the need to properly reproduce the ear's acoustic impedance. The AECM206, in conjunction with APx Series analyzers, accessories and software, provides the user with a complete system enabling precise and repeatable electro-acoustic testing of headphones and insert earphones (earbuds). AECM206 Headphone Test Fixture The Headphone Test Fixture is shipped fully-assembled and ready to use upon arrival, with occluded ear simulators (microphones with acoustic couplers) and preamplifiers installed and connected to BNC-terminated coaxial cables. The microphone/preamplifier pairs are TEDS-compliant, CCP-powered and calibrated. TEDS—Transducer Electronic Data Sheet—programming allows microphone identification and calibration information to be read by a connected instrument, such as the Audio Precision APx1701 Transducer Test Interface. Two sets of pinnae (hardness Shore OO-35 and A-25 respectively) are provided with the unit. The pinnae are symmetric, which offers convenience when testing stereo headphones and earphones. The AECM206 is also delivered with an adapter for the CAL250 sound level calibrator (optional), product documentation and disassembly tools. Calibrated Instrumentation and Accessories "The increasing complexity of audio devices—Bluetooth™ headphones with ANC, for example—is creating ever-more complicated test scenarios," said Dave Schmoldt, Audio Precision Chief Executive Officer. "AP continues to help engineers reduce that complexity by providing test solutions that support analog, digital and electro-acoustic measurement. We're thrilled to now have the AECM206 as part of that test solution." The AECM206 retails for US$11,024, or US$11,232 in an optional hard-shell roller case. About Audio Precision Contact
