Abstract
An acoustical theory of the photoacoustic effect is presented in such a way that expected signal strengths from microphones in gaseous media and from hydrophones in liquid media can be compared. For liquid media it is shown that the sample acoustic impedance is often quite important. Numerical comparisons of hydrophones and microphones indicate that photoacoustic signals from the former can be stronger than from the latter.Keywords
