Abstract (en)

A system (10) for acquiring data representing sound in a human or animal body. The system comprises a disk shaped piezoelectric element (30) with a fist side (31) and a second side (32) opposite the first side (31). The piezoelectric element (30) is capable of generating, when exposed to the sound, an analogue electrical signal representing the sound, and the first side (31) is adapted for placing in acoustic contact with the skin of an animal or a human being, and the second side (32) is directly exposed to ambient air, and a device (20) for receiving the electrical signal generated by the piezoelectric element (30). The piezoelectric element (30) can be covered by a protective coating. The electrical signal is sampled at a sampling frequency as high as 96 kHz.
