Acoustics Physics Student Science Kits

• The acoustics kit allows students to carry out numerous experiments on acoustics independently
• A wide variety of sound sources are studied 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
• Includes extensive study of various musical instruments
• Different high-pitched tones are generated by means of a monochord and the ensuing intervals are calculated experimentally
• These studies can easily lead over to a study of musical notes
• Includes comprehensive experiment descriptions (student / instructor version)

Experiments:

• 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
