</script>The source of the acoustic signal is the heat, in whatever manner it may be created from the energy of light absorbed by the sample. The whole process, beginning with the created heat eQ and ending when the pressure signal eP arrives at the acoustical detector, can be described using the formalism of thermodynamics.
