Ultrasound may also aid in the detection of heart disease, tumors, gall stones, and other disorders. Ultrasound is used by manufacturers to measure the wall thickness of metal or plastic pipes and to test the concentration of particles in inks and paints. Sonar devices locate schools of fish, enemy ships, and underwater obstacles through the use of ultrasound. Geophysicists can use sound in exploring for minerals and petroleum and also locate possible mineral or oil bearing rock formations. One way to use sound in industry is through music.
Music is based on sound waves which are used in instruments and amplifiers.
Scientists have invented whistles and other devices that produce ultrasound. An ultrasonic transducer converts electric energy into ultrasonic waves. These waves can also be converted into electric energy by transducers. One way to use the sound wave in science is a sonar wave. A sonar wave uses a sound wave to see how far or deep something is.
