title: Evaluation of otoacoustic emissions in clinically normal alert puppies.
abstract: OBJECTIVE
  To evaluate distortion product otoacoustic emission (DPOAE) measurements in puppies with normal hearing.
  
  
  METHODS
  23 clinically normal 7.5-to 10.5-week-old puppies.
  
  
  METHODS
  A cross-sectional study was performed. The DPOAE measurements were obtained with a commercially available distortion product otoacoustic measurement system and were performed in a quiet, non-sound-attenuated room. All measurements were obtained from alert puppies and were repeated 1 or 2 times to ensure that the measurements were replicable. Results that were a minimum of 8 dB higher than the noise floor were accepted. Values from the first trial in which emissions were obtained at all test frequencies were used for analysis.
  
  
  RESULTS
  Otoacoustic emission measurements were easily obtained, robust, reliable, and consistent with auditory brainstem response and behavioral results.
  
  
  CONCLUSIONS
  Hearing screening in alert puppies can be accomplished reliably and rapidly with otoacoustic emissions testing. Results supported the possibility of the use of DPOAE measurement in hearing screening of dogs.
