Brief descriptions of several of the laboratory experiments which have been incorporated into an acoustics course for music majors. Includes vibratory motion and sound generation, nature, speed, and pitch of sound, spectrum analysis and electronic synthesis of musical sound and some conventional sound experiments. (Author/TS)

Based on doctoral dissertation by first author under direction of second author. (Author)

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

In studies with 22 normal hearing adults and two hearing impaired children (12-13 years old), speech was presented under different degrees of optical distortion. (CL)

Describes some undergraduate laboratory experiments in acoustics which involve the analysis of speech and musical instrument sounds and the general analysis of the frequency range of complex sounds. (HM)

A bricoleur is a person who lives by recycling old materials. This article describes a bricolage, a junk sound sculpture, constructed mainly of junk metal. Selected readings are included. (KC)

The second part of a three-part series, this article describes sound measurement, effects, and indoor learning activities. Thirty elementary school activities are described with appropriate grade levels specified. (Author/CS)

Some topics included are: the relative merits of a programmable calculator and a microcomputer; the advantages of acquiring a sound-level meter for the laboratory; how to locate a virtual image in a plane mirror; center of gravity of a student; and how to demonstrate interference of light using two cords.

Discusses one of the newest methods used to probe the upper atmosphere using naturally generated infrasound from ocean waves. (GA)

Describes the following: a low-pressure sodium light source; a design of hot cathodes for plasma and electron physics experiments; a demonstration cart for a physics of sound course; Bernoulli force using coffee cups; a spark recording for the linear air track; and a demonstration of the effect of altering the cavity resonance of a violin. (GA)

Describes research and technological development relating to navigation on the oceans via sound, particularly via underwater sound. (SL)

Examines what fourth-grade students learned by using computer-based tools intended to help them understand sound and music. Findings provide critical information for future instruction with the goal of supporting learning about sound and music from such tools. They also indicate the need for more studies examining learning from computer-based…
