A microphone for detecting vibrations at two or more locations on a surface such as a body surface. The microphone comprises two or more vibration sensors, where each vibration sensor has a diaphragm. The diaphragms are arranged in an overlapping array so that vibrations at at least one location on the surface are detectable simultaneously by at least two of the vibration sensors. The invention also provides a system for recording sounds from a surface comprising one or more microphones of the invention and a processor configured to determine a vibration at one or more locations of overlap between the diaphragms.
