Abstract
Abstract Sound heads (SK1 to SK3) are fixed, distributed peripherally, on the part of the body, e.g. an arm or leg. Each of the sound heads is able to transmit ultrasonic signals along a measuring section (MS1 to MS3) leading to another sound head, which signals are received by the other sound head. The sound heads can consist of angularly arranged sound members (14). In this way, all three sides of a polygon formed by the sound heads are measured, from which measurements the surface area of the polygon can be determined.
