This article deals with the adaptation of a commercially available Pocket PC for use as a voice dosimeter, a wearable device that measures the vocal dose of teachers or other individuals on the job, at home, and elsewhere during the course of an entire day. An engineering approach for designing a voice dosimeter is described, and design data are…

The phenomenon of resonance is applicable to almost every branch of physics. Without resonance, there wouldn't be televisions or stereos, or even swings on the playground. However, resonance also has undesirable side effects such as irritating noises in the car and the catastrophic events such as helicopters flying apart. In this article, the…

This book is divided into chapters based on the general subjects of mechanics, air power, water power, electricity and magnetism, chemistry, acoustics, and optics.

Exercises in speech and…

Compiled to serve as a working tool for those involved in optical storage research, planning, and development, this bibliography contains nearly 700 references related to the optical storage and retrieval of digital computer data. Citations are divided into two major groups covering the general and patent literatures. Each citation includes the…

In order to study signs of stress in speech directed to children at risk for abuse, sentences matched on content were collected from audio recordings of adult-child interactions. The children were audiotaped during an unstructured interaction with both their own mother and an unrelated mother. A total of 40 sibling pairs, each including one…

Listening to sounds is a very important way of learning about one's environment, but there is more to sound than just listening. Many educators feel that it is important for students to gain some understanding of the physical phenomena of sound. This teacher's guide contains lesson plans, background information, and activities designed…

A study of the phonetic combination of a constrictive consonant (specifically, [f], [v], and [r]) and a vowel in French using x-ray and oscillograph technology focused on the speed and process of articulation between the consonant and the vowel. The study considered aperture size, nasality, labiality, and accent. Articulation of a total of 407…

Presented is an environmental noise module developed as an instructional guide for teachers in grades seven through twelve. The guide consists of eight lecture summaries on noise-related topics including characteristics of sound, sound measurement, noise control, and the effects of noise on humans.
