A reliable and holistic approach to evaluating hearing and cognitive auditory processing in adult and aged companion dogs.. Presbycusis affects both peripheral and central auditory systems in people and dogs. While comprehensive behavioral hearing tests exist for people, veterinary audiology lacks methods to assess central auditory function in dogs. This study aimed to develop behavioral hearing tests for dogs. We introduced two novel assessments: the Enclosed Canine Hearing Observation (ECHO) test and the Evaluation of Auditory Reward Response (EARR) test. Fourteen adult dogs with normal hearing, five deaf and five senior dogs were included. The ECHO test evaluates a dog's ability to detec…

A dog whistle (also known as silent whistle or Galton's whistle) is a type of whistle that emits sound in the ultrasonic range, which humans cannot hear but some animals can, including dogs and domestic cats, and is used in their training. It was invented in 1876 by Francis Galton and is mentioned in his book Inquiries into Human Faculty and Its Development, in which he describes experiments to test the range of frequencies that could be heard by various animals, such as a house cat. Dog whistles were invented to explore auditory perception in animals and have since evolved into tools primarily used for dog training, with commercial developments leading to more specialized and efficient des…

Hearing ancient sounds through modern ears

Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The academic field concerned with hearing is auditory science. Sound may be heard through solid, liquid, or gaseous matter. It is one of the traditional five senses. Partial or total inability to hear is called hearing loss. In humans and other vertebrates, hearing is performed primarily by the auditory system: mechanical waves, known as vibrations, are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal lobe). Like touch, audition requires sensit…
