DESIGN AND CONSTRUCTION OF A SONOMETER

DESIGN AND CONSTRUCTION OF A SONOMETER

ABSTRACT

When one thinks about various musical sound he listened to daily he would realize the very important role played by some instrument include. The guitar, piano and violin, which operate on the principles of vibration of, stretched string. CF has therefore become necessary that it study the condition under, which stringed instrument vibrates to give high quality musical notes. This study is basically the investigation of the laws governing the vibration of a stretched string, it is carried out by the use of SONOMETER.
