Quantitative analysis of a closed photoacoustic cell that uses a high compliance piezoelectric transducer [PDF]
, 2005 A treatment of the operation of low-frequency closed photoacoustic cells is presented, which considers the compliance of various cell elements. The optimum detector, according to our predictions, has a sensor whose compliance is large compared to that
