He also noted that the ability to hear higher frequencies declined with age. Reportedly, Galton derived much pleasure from demonstrating this deficit to older people. From his early tests on humans, Galton adapted his new whistle to test the hearing of various animals. He attached the whistle to a long tube with a rubber squeeze ball at the other end. Galton would go the enclosures of different animals, at the zoo, use the long stick to reach toward the animals and squeeze it to make a pitch.
He was also a fan of walking through the streets and seeing which types of dogs could hear higher pitches small dogs were better at this than large dogs. Galton noted that natural selection had produced the best hearing of shrill notes in cats. Early comparative psychologists took the crude animal assessment techniques of Galton and refined them.
The whistle was combined in the psychological laboratories with acoumeters, tuning forks, and other hearing instruments.
The Galton whistle was manufactured with tables of vibration rates to five digits. Early psychologists made design changes of their own for the necessity of their experiments.
At Harvard, Frank Pattie invented a blower that could deliver a constant, steady stream of air pressure through the whistle for up to a half hour. Despite its simplicity, the whistle was used in highly complex and revealing psychological experiments. From its creation in , the Galton Whistle is still in use today, most commonly known as a dog whistle. The Archives of the History of American Psychology is home to the older version of the Galton whistle pictured above.
APS regularly opens certain online articles for discussion on our website. A dog whistle can be used in a variety of different ways. However, the dog whistle can be used to stop barking, train basic obedience, or even modify specific behaviors. Remember: without proper training, the dog whistle is just another sound in the world.
Just like with other sounds, they will become desensitized to it and learn to ignore it over time, if not used properly! The number one tip when working with dog whistles is to not use them too frequently! If you abuse this training tool, it will become completely ineffective and cause discomfort for your dog. If you are trying to train your dog to stop barking, blow the whistle and wait for your dog to re-focus on you.
Remember, this whistle is used to get their attention, but then it is your job to use your calm assertive energy, body language, and voice to tell them exactly what you want. After you have given the desired command, wait a few seconds to see if the dog will repeat the negative behavior.
If they do, blow the whistle again and repeat your command with more energy and intensity. The hearing range of dogs is almost double that. The dog whistle, which sounds silent to humans, produces sounds in the kilohertz range that dogs can hear.
Dogs have better hearing than humans both because they can hear these high-frequency sounds, and they can hear sounds from farther away. This is because of the way their ears are designed.
