Abstract
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.
Claims7
A pulse wave detecting apparatus, comprising:
- a pulse wave sensor which detects a pulse wave produced from a living subject and outputs a pulse wave signal representing the detected pulse wave;
- a signal converting means for converting, according to a predetermined relationship between magnitude of pulse wave signal, and frequency, the pulse wave signal outputted from the pulse wave sensor, into a converted signal having an audible frequency;
- and
- a sound outputting device which outputs a sound representing the converted signal provided by the signal converting means.
