Sound needs vibration to make noise. When an object vibrates, it creates oscillations in the surrounding air molecules, transmitting a wave of pressure variations that our ears perceive as sound. The other terms mentioned—crest, frequency, and ears—are related but represent different aspects of sound. Crest refers to the highest point of a wave, frequency is the number of oscillations per unit of time, and ears are the organs responsible for hearing and interpreting sound.
