The Auditdata DD65 with Audiocups is a circumaural (over-ear) audiometric headset designed to provide superior passive noise attenuation. It features a standard 1/4-inch stereo jack for compatibility with most clinical and diagnostic audiometers. Built on the DD45 transducer model, the DD65 includes specially designed Audiocups for testing in high-noise environments or settings where a sound booth is unavailable.
