DPOAEs or Distortion Products Otoacoustic Emissions are a keystone technique for understanding hearing loss and hair cell loss in preclinical animal models. Engineers at TDT saw a need for a high-quality probe microphone for DPOAEs and they delivered.
TDT’s DPM1 is a low-noise high-gain probe microphone. It is designed for recording distortion products from primates and preclinical models of hearing loss in rats, mice, gerbils, and other model organisms.
The innovative design uses a state-of-the-art microphone with a frequency bandwidth of up to 40kHz. This allows users to accurately record the two frequencies and the DPOAE.
