SS 776

Ultra-high frequency microphone kit, 80kHz
Ultra-high frequency (UHF) artificial ear is an ear simulator that simulates the way that an earplug catheter is inserted into the ear canal or auricle, and the acoustic performance of the earphone is measured by simulating the
coupling between the earphone and the human ear. The SS 776 uses a 1/4 inchmicrophone internally. The coupling cavity and preamplifier are integral andnon-detachable. It is a prepolarized pressure field measurement microphonekit.
The SS 776 is positioned as a cost-effective high frequency microphone forultrasonic acoustic measurement, specifically for in-ear headphone productaudio production line testing. With MegaSig PM 0083 IEPE signal conditionerfor t he best test results.
