| The sound waves reinforce the shock wave until it finally explodes aspherically. |
| An echocardiogram can also use sound waves to determine the direction of blood flow through the heart. |
| Ultrasound uses high frequency sound waves and magnetic resonance imaging uses radio waves. |
| The low, hypnotic hum created by the amplification of sound waves as they traveled through water reverberated throughout the dark tank. |
| These new greener chillers use sound waves for cooling instead of environment-damaging chemical refrigerants linked to global warming. |
| Compared with total atmospheric pressure, airborne sound waves represent extremely small pressure changes. |
