### Physical Property of Metal - Sonority

Concept Explanation

## Sonority of Metals

When metals pipe strike each other, they produce a ringing sound, the property by virtue of which metal object produce a ringing sound when struck with a hard object is called sonority. Object like wind chimes and bells make use of this property of metals.

Metals are Sonorous. This means that metals make a ringing sound when we  strike them.

Sonorous means capable of producing a ringing sound. If we drop a metal coin or a metal utensil on the floor of our house, we hear a ringing sound. And when the clapper (or hammer) of an electric bell strikes the metal gong, even then a ringing sound is produced. So, the metal objects make a ringing sound when we drop them on a hard floor or strike them with a hard object. We say that the metals are sonorous (or capable of producing a ringing sound). Suppose we have two boxes, one box made of metal and the other box made of wood, which are similar in appearance. We can tell which box is made of metal by striking them with a small hammer. The box which produces a ringing sound on being struck by the hammer will be the one made of metal. Metal sheets are used for making bells (like the bicycle bells and temple bells). The use of metals for making bells is based on their being sonorous.
