by John Weeks Moore

Audibility Of Sound. M. Savart, speaking of the inferior limit of the number of vibrations per second which compose a sound just perceptible to the human ear, says he had before proved by experiments, that the limit was much further extended than he had generally supposed. For example, sounds are very distinctly heard which result from more than fifty thousand oscillations in a second. By means of a new apparatus, he can now show that sounds are distinctly perceptible, and even strong, when composed of no more than eight vibrations in a second.
