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.
