The acoustics kit allows students to carry out numerous experiments on acoustics independently. A wide variety of sound sources are studied to begin with and the concepts of noise, bangs and tones as well as pitch and loudness are investigated. Waves along a rope are used to illustrate harmonic vibrations and overtones. There is also some extensive study of various different musical instruments. Different high-pitched tones are generated by means of a monochord and the ensuing intervals are calculated experimentally. These studies are expanded to other instruments and can easily lead over to a study of musical notes.
Experiment Topics:
- Noise, bangs, pure tones
- Vibrating air columns
- Whistles and pipes
- Vibrating bars, plates and bells
- Infra-sound
- Ultra-sound
- Tuning fork with plotter pen
- Travelling waves along a rope
- Velocity of propagation of sound
- Moving sources of sound (Doppler effect)
- Plate vibrations (Chladni figures)
- Vibrations of a bell
- Standing waves on a rope, overtones
- Sounds of musical instruments
- Timbre of the human voice
- Measurement of wavelength (Kundt figures)
- Resonance
- Helmholtz ball resonators
- Sound analysis
- Loudness
- Pitch of string instruments
- Pitch of wind instruments
- Reed pipe
- C-major scale and its intervals
