Comments on "What is silence? Therefore, what is sound?" - A discussion of Brownian motion and the threshold of hearing (L).

ABSTRACT

This Letter to the editor is a comment on an article in the JASA Forum by William Yost. It pertains to a reference he made to prior work that indicates the possibility that the human threshold of hearing in the most sensitive region may be limited by Brownian motion of the air molecules, also called thermal noise. I present additional data and my own observations that support this contention.
