Why is db spl used to test the hearing in animals?
Answers
Explanation:
Reporting the frequency range for hearing in dogs and other species is not a straightforward task - the "how" of determining hearing frequency ranges must first be explained. Testing in animals differs from the method commonly used with humans of voluntarily reporting if a sound is heard. When determining the frequency range in animals, an investigator usually must first train the animal to respond to a presented sound stimulus by selecting between two actions using rewards. Often this response is to try to drink or eat from one of two dispensers when a sound is heard. The sounds are randomly presented from one side or the other, and the subject must select the right dispenser (on the same side as the stimulus) to get the reward; otherwise no food or drink is dispensed.
