High Frequency Animal Testing

High Frequency ABR & DPOAE for animal testing at up to 32kHz

Over 40 years of engineering design experience, combined with unsurpassed expertise in evoked responses, have culminated in the next generation bio-amplifier to bring you superior data quality for evoked potentials and otoacoustic emissions.

We are pleased to offer High-Frequency Options for SmartEP, SmartEP-ASSR, and SmartDPOAE. Available on our Duet platform, using our High-Frequency Transducers for ABR, ASSR, and DPOAE testing at up to 32kHz.

Researchers have used our High-Frequency Option, speakers, and microphones to record AEP and DPOAE on a wide range of animals, including dogs, mice, rats, guinea pigs, mini pigs, primates, gerbils, and chinchillas.
