Summary
Accurate hearing tests are crucial for dogs due to high deafness rates. The auditory steady state response (ASSR) shows promise as an objective, rapid hearing assessment tool for veterinary diagnostics.
Area of Science:
- Veterinary Medicine
- Audiology
- Animal Health
Background:
- High incidence of deafness in various dog breeds necessitates reliable hearing assessment.
- Current audiologic tools include brainstem auditory evoked response (BAER) testing.
- Emerging electrophysiologic tests like otoacoustic emissions and auditory steady state response (ASSR) are under investigation.
Purpose of the Study:
- To highlight the importance of accurate hearing screening and assessment in dogs.
- To introduce otoacoustic emissions and ASSR as potential audiologic tools in veterinary medicine.
- To emphasize the need for standardized protocols to improve BAER testing and inter-site consistency.
Main Methods:
- Review of current and emerging electrophysiologic hearing assessment techniques in veterinary audiology.
- Discussion of the principles and applications of BAER, otoacoustic emissions, and ASSR.
- Emphasis on protocol standardization for diagnostic accuracy.
Main Results:
- The auditory steady state response (ASSR) is identified as a promising objective test.
- ASSR allows for rapid testing across multiple frequencies.
- ASSR enables simultaneous testing of both ears.
Conclusions:
- Standardized protocols are essential for accurate and reproducible BAER testing in animals.
- ASSR presents a valuable, objective method for comprehensive hearing assessment in veterinary diagnostics.
- Further adoption of ASSR can enhance canine hearing healthcare.
