Abstarct: Measuring body volume is done by various methods. The techniques used in this area include the use of a hand-made device called acoustic volume meter, which consists of three parts, mechanical, electronic, and computer. With this device, you can measure the volume of objects in a non-destructive way. Its performance is baxsed on changing air volume. Changing the air volume causes a change in air pressure. Changing the volume of air is done by creating sound waves from a speaker and measuring the pressure change caused by volume changes using two microphones. Measuring the volume of air is measured by measuring inside the device. One can approximate the relationship between the change in air volume caused by the placement of the measuring object and the volume of the object being measured. An artificial neural network has been used to achieve this connection. Each time a constant temperature measurement should be performed
