Sound of the sea that is heard when a seashell is placed up to your ear is explained by resonance. The seashell has a set of natural frequencies at which it will vibrate. If one of the frequencies in the room forces air within the seashell to vibrate at its natural frequency, a resonance situation is created. And always, the result of resonance is a big vibration - that is, a loud sound. In fact, the sound is loud enough to hear. So, we hear some kind of sound whne we keep a see shell near our ear
