The Bell as Ben Heard It
Thanks to modern computer modeling, we may have a closer idea of exactly how the Bell sounded when Benjamin Franklin heard it. In 1999, graduate students from Pennsylvania State University were able to digitally create a structural model of the Liberty Bell. From this computer model, they were able to mathematically equate the vibration of the Bell and add sound. Knowing that the tone of the Bell was E-flat, they were able to come up with a fairly close approximation of the original sound of the Liberty Bell.
