Abstract
Direct photoacoustic spectroscopy setups oftentimes employ acoustic resonators to enhance the photoacoustic signal and suppress acoustic noise from the environment. In this contribution the coupling of an idealized sound source to a cylindrical resonator is simulated and shows the dependence of the coupling efficiency on the relative position of the sound source with respect to the resonator. The simulations reveal the spatial dependence of the ideal incoupling positions as a function of the resonator modes. The results are important for setups that spatially separate acoustic sound generation and detection.
