iphone’s default ringtone
where did it come from? bell labs!
“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. However, when pressed, a majority of test subjects wanted the old bell ringer back. Not much has changed since from the days of the early Human Factors research, the brain still works the same, but the technology obviously allows for more finite control of the sounds a ringtone creates.” more
