“Scientists at Bell Laboratories, Human Factors Research Lab performed numerous studies on ringers, from buzzers to thumpers. They studied tonal quality and duration along with the decibel levels needed for the brain to recognized the call alert. They even tested the Grandpa to the iPhone “old phone” ringtone. In 1956, 300 research subjects in Crystal Lake, Illinois found the “musical tone ringer” to be “pleasant,” but took most test subjects over a week or so to get accustomed to it.
