PREFACE

 

 

The first chapter in the microphone section deals with the basic ways in which various types of sound field are propagated and how they interact with a microphone.

The very basis of the acoustical part of audio engineering is the behavior of air. This is the medium in which we live and breathe, and whose pressure fluctuations we are so good at detecting with ears honed by long ages of natural selection.

John Eargle begins with the basics of frequency, wavelength, and the speed of sound (which we note varies somewhat with temperature). He moves quickly on to acoustical power, sound pressure and decibels, and shows how the inverse square law determines the way that intensity falls off with distance in a free sound field, and the relationship ...
