The applied procedure of thermal effusivity determination for liquid samples taking advantage of photoacoustic signal amplitude measurement with microphone registration is presented. The experimental results obtained for distilled water and ethyl alcohol are shown to illustrate the sensitivity of the applied procedure. The results are in reasonable agreement with the data obtained from the literature.
