"The book gives a good and detailed insight into the times of pre-numerical acoustics around 1800. Robert T. Beyer's book can be recommended to those willing to study in detail what the thoughts of a leading experimental physicist were-despite that they were all called 'philosophers at that time." (Heinrich Metzen, Noise Control Engineering Journal, Vol. 64 (5), September-October, 2016)

• PART I Numerical Ratios of Vibrations Primary Ratios.- PART II: Characteristic Vibrations of Sounding Bodies.- General Remarks.- PART III The Propagation of Sound.- On the Propagation of Sound through Air and through Other Gaseous Fluids.- PART IV On The Sensation Of Sound Or Hearing.- Human Hearing.
