DEMONSTRATIONS IN ACOUSTICS

Dr. Richard E. Berg, University of Maryland

Demonstration 1. Frequency, amplitude and tone quality (9 minutes)

A waveform generator, a loudspeaker and an oscilloscope are used to demonstrate the effects of varying the period, the amplitude and the wave shape of a sound wave

Demonstration 2. Damped and driven oscillations - resonance (9 minutes)

Mass-on-spring systems are used to analyze and graph the phenomena of damped and driven harmonic motion. The condition for resonance is discussed and examples shown (9 min.)

Demonstration 3. Coupled oscillations (6 minutes)

Coupled resonance are studied using several mechanical systems.

Demonstration 4. Glass breaking with sound resonance (4 minutes)

Demonstration 5. Bell in vacuum (5 minutes)

The sound of a bell in a jar becomes inaudible as the air is pumped from the jar. A gauge shows the air pressure in the jar.

Demonstration 6. Speed of sound (4 minutes)

The speed of sound is determined using an electronic wave generator, a loudspeaker, a microphone and an oscilloscope.

Demonstration 7. Reflection from concave surfaces (5 minutes)

Light rays are focused by a concave mirror to a point. The audio analog experiment is performed using a concave spherical reflector. Finally, a beam of sound is produced using a speaker at the focal point of one reflector and is detected by a microphone placed at the focus of a second reflector.

Demonstration 8. Refraction - sound lens (3 minutes)

Light rays are focused to a point by an optical lens. Acoustic lenses are produced by filling balloons with various gases, both heavy and light. Focusing and defocusing of sound waves is illustrated (3 min.)

Demonstration 9. Interference (11 minutes)

Interference of sound is demonstrated using a Qunicke's interference tube. Young's two-source interference is illustrated visually with Moire patterns, and then acoustically, using loudspeakers. This experiment is first performed in the studio, and then outside, to eliminate effects of reflection off of walls, floor and ceiling. An experiment is presented illustrating the effects of reversing the phase between the loudspeakers.

Demonstration 10. Diffraction (5 minutes)

Using a sound collimator constructed from a speaker and a sound absorbent tube, diffraction effects are shown to be greater at low frequencies than at higher frequencies.

Demonstration 11. Doppler Effect (3 minutes)

The Doppler Effect is shown by throwing a ball with a 3 kHz electronic whistle inside.

Demonstration 12. Beats (5 minutes)

Using two audio oscillators, a mixer amplifier, a loudspeaker and a dual trace oscilloscope, various aspects of beats are studied. The individual waves are shown, with the sound varying in intensity as the phase of one wave shifts with respect to the other.

Demonstration 13. Shive wave machine (9 minutes)

Demonstration 14. Standing sound waves (8 minutes)

A standing wave is created between two speakers about a meter apart. One source is then replaced by a metal plate, and a standing wave is produced by the wave from the speaker with the reflected wave. Some details of standing sound waves are shown using a Kundt's tube driven by an audio oscillator.

Demonstration 15. Reflection of pulses (10 minutes)

Reflection of pulses of a transverse wave from fixed and free ends is examined using a Shive wave machine. A detailed study is then presented showing how sound pulses reflect off open and closed ends of an air column.

Demonstration 16. The overtone series (10 minutes)

The overtone series through the tenth harmonic is illustrated using a Fourier synthesizer. First, the individual tones of the series are shown and then the sum is obtained. The harmonics obtained in the air columns are illustrated. Harmonics are excited in a violin string by bowing while touching it lightly at 1/N of its length. The harmonics of an aluminum rod are excited by stroking the rod with resin on fingers. Chords are shown by the Fourier synthesizer and Savart's disk demonstration.

Demonstration 17. Standing waves in a string (6 min.)

Demonstration 18. Mersenne's laws (6 minutes)

A two-stringed sonometer is used to show the effect of changes in length, tension and mass/length on the fundamental frequency of a wire under tension.

Demonstration 19. Standing waves in air columns (11 minutes)

A tuning fork is used to excite the fundamental mode in an air tube. The relationship between the fundamental modes of open and closed tubes of the same length is shown. Several other examples are also shown.

Demonstration 20. Basic trumpet acoustics (6 minutes)

Blowing a plastic tube at one end in the manner of a trumpet shows that the tube behaves acoustically like a closed tube, with the lip end closed. The technique of obtaining the notes on a standard trumpet is demonstrated.

Demonstration 21. Chladni plates (10 minutes)

The use of magnetostriction in a nickel tube to drive Chladni plates is explained and demonstrated.

Demonstration 22. Fourier synthesis (9 minutes)

Triangular, square, sawtooth and pulse train waves are synthesized. The summed wave and the harmonic being added are shown simultaneously on a dual-trace oscilloscope, and the tone is heard as the harmonics are added or removed.

Demonstration 23. Fourier analysis (11 minutes)

Sound curves and Fourier spectra are displayed simultaneously for some standard waves.

Demonstration 24. Resonance curves (12 minutes)

An oscilloscope is used to show the resonance of several devices and a resonance curve is plotted and shown.

Demonstration 25. Modulation (12 minutes)

Frequency modulation, amplitude modulation and balance modulation are demonstrated.

Demonstration 26. Musical synthesizer fundamentals (12 min.)

Demonstration 27. Vocal formats (8 min.)

Demonstration 28. Audio spectrograms (10 min.)

Demonstration 29. Effect of gas on voice (4 min.)

CONSERVATION LAWS OF MECHANICS

A demonstration is performed by firing two bullets into identical blocks of wood, but at different points on the two blocks. This gives one of the blocks angular momentum, yet the blocks travel to the same height, thus showing the conservation of linear momentum and energy. Conservation of angular momentum is described and applied to the block problem. Sufficient explanations of the three conservation laws are provided. (16 minutes)

Chapter 4 examines the effects on a model bridge of low, medium and high wind speed with a high frequency of pulses.

Chapters 5 to 18 examine the properties of waves, with particular emphasis on the properties of standing waves. Topics covered include amplitude, frequency, fundamental frequency and vortices.
