Sound Wave Demonstration Fixture

 

Science Club  - Class 4

Measurement and Classification

 

Sound Instrument-2

 

Sound is created when something vibrates back and forth. The vibration pushes into molecules and creates a wave of sound. The sound wave demonstration fixture is designed to demonstrate this principle and to give students hands on experience with sound wave  transmission, amplification  and measurements.  The fixture uses the classic string telephone to demonstrate sound wave transmission, a microphone for amplification and an oscilloscope for measurements. 

 

A sound wave is generated by students speaking  into the left resonator can. The sound wave is transmitted thru the transmission cord to the right resonator and picked up by a microphone.  The amplifier / speaker is used to amplify the sound wave and direct it back to the students. The sound wave signal is also displayed on an oscilloscope. The oscilloscope can measure both the frequency and amplitude of the signal. Students can feel, see and hear that sounds are indeed caused by vibrations.
