Mouse Auditory Brainstem Response Tester

The Mouse Auditory Brainstem Response (ABR) testing system induces and records potential responses in the cerebral cortex by providing sound stimuli of different intensities. The test results are used to determine the condition of hearing loss and are commonly used for hearing screening and threshold evaluation. The device has four channels and can simultaneously test the auditory brainstem response of four mice. The device comes with a triple sound-electric isolation system, achieving a sound insulation effect of 50dB.
