Abstract
An acoustic wave consists of a variation in pressure as time passes. To measure or analyse an acoustic waveform, it is usual to generate an electrical analogue of the pressure variation by means of a transducer. Instead of dealing directly with the pressure changes, we study a changing voltage or current which has the same behaviour with respect to time. If we want to generate a sound we also start with an electrical waveform, and again use a transducer to convert it into a pressure change.
This particularly rapid, unintelligible patter isn’t generally heard, and if it is it doesn’t matter.
