Now Audible! ... The Hidden (Infrasonic) Music of the Heart

Click on the Audiogram Above to listen to sonified (pitch-shifted) cardiac infrasonic waves detected by Laser Doppler Vibrometry (LDV) over the carotid artery. The first set is at rest, the second set after exercise. To find out more about cardiac infrasound and its possible role in homeostasis, see the just-published monograph "Vital Sounds: The Hidden Music of the Heart" in the adjacent post. Is this the next big thing in homeostasis? Stay tuned! (LDV: PolyTec, Plymouth, MI)
