A pulse wave detecting apparatus, including a pressure pulse wave sensor 30 which detects a pulse wave produced from a living subject and outputs a pulse wave signal SM representing the detected pulse wave, a signal converting device 78 which modulates, by using the pulse wave signal SM as a modulating signal, an audible frequency of a to-be-modulated signal, and thereby provides a modulated signal having audible frequencies, and a speaker 62 which outputs a sound representing the modulated signal provided by the signal converting device 78.
