WebAug 28, 2024 · Sound is a type of energy that travels through the air, or any other medium, as a vibration of pressure waves. It is generally caused by an object vibrating, such as a vocal cord, a musical instrument, or a speaker. The vibrations create compressions and rarefactions in the air, which our ears sense as sound. WebSep 1, 2024 · One common way to measure sound waves is to use a sound level meter. This device measures the intensity of sound waves in decibels. The higher the decibel level, the louder the sound. Another way to measure sound waves is to use a spectrometer. This device measures the frequency and wavelength of sound waves. track flight aa730
