Plain-English summary
A group of nine healthy mixed-breed dogs underwent a hearing test using a method that involved sending sound clicks at different speeds and volumes. The researchers found that by increasing the speed of the sound clicks, they could get reliable hearing test results much faster than usual. This new approach could help veterinarians quickly assess a dog's hearing ability without compromising the quality of the results.

Abstract
The aim of this study was to determine if high stimulus repetition rates could reduce the time taken to obtain brainstem auditory evoked response (BAER) waveforms of equivalent quality in dogs. Click-evoked BAER waveforms were obtained from nine healthy, adult, mixed-breed dogs at stimulus intensities of 70, 60, 50 and 40 decibels (normal hearing level) (dBnHL) and stimulus repetition rates of 11, 33 and 91 clicks-per-second (cps). The quality of the BAER waveforms was kept constant by ensuring all waveforms achieved the same signal-to-noise (SNR), as shown by their F(sp) value of 3.1. Increasing the stimulus repetition rate from 11 to 91Hz significantly (P<0.01) reduced the median time to obtain BAER waveforms of equivalent quality by 3.29-14.07s per waveform, or alternatively, increased the recording speed by 4.6-13.7 times per waveform (depending on the stimulus intensity). The use of high stimulus repetition rate BAER shows significant promise for the rapid assessment of auditory function in dogs.
