Describes the musical sounds which can be found in unexpected places, and presents classroom projects which will enable heretofore visually oriented students and teachers to rediscover their ears. (BD)

Boundaries in running speech are not all equally obvious acoustically. The research reported here is concerned with identifying the acoustic characteristics that trigger the listener's response to boundary signals. The eventual goal is to establish the relevance of the boundary to the syntactic and semantic structure of the message. (Author/TL)

Summarizing research activities from October 1978 to August 1979, this is the fifth annual report of research on speech processing conducted in the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information on instrumentation developments and software support. The…

Summarizing research activities from January 1982 to December 1982, this is the eighth annual report of research on speech perception, analysis and synthesis conducted in the Speech Research Laboratory of the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information…

This report describes the room arrangement, design, and appearance of 152 Title IV-A Day Care centers in Philadelphia. A series of 27 items on a section of the Daily Care, In-Room Observation Guide was used to provide an overall description of rooms in day care and to identify differences in features for different types of programs. Data were…

These projects utilize musical instruments to teach the physics of sound by investigating standing waves in strings and plates, main resonance of stringed instruments, loudness curves, and analysis of tones. Can be adapted for secondary level or college level instruction. (MLH)

Underwater intelligibility of three standard word lists is evaluated in two experiments. Results indicate that words which are equated for difficulty in normal conditions are likewise equated under water. Phoneme distortion was examined in a multiple choice test which showed fricatives and place of production to be most affected under water. (SC)

The "Science Related to Life" textbooks are written to supply the need of elementary science teachers with textbooks that can be used independently by pupils. Throughout the series the author has kept in mind the aims of elementary science, as recognized by modern courses of study, namely to develop in pupils an interest in the natural…

This paper assesses certain properties of human mental processes by focusing on the tactics utilized in perceiving speech signals. Topics discussed in the paper include the power spectrum approach to fluctuations and noise, with particular reference to biological structures; "l/f-like" fluctuations in speech and music and the functioning of a…

A review of research on television's major compositional factors was undertaken to determine the status of such research and to note the major variables involved in the structure of television pictures. It was found that such research could be grouped in four categories--lighting and color, staging, editing, and sound--and that these areas covered…

THIS DOCUMENT REPORTS THE PROGRESS FROM SEPTEMBER 1, 1961 TO FEBRUARY 1, 1962 OF AN EXPERIMENTAL PROGRAM IN SPEECH CONTROL. THE TOPICS DISCUSSED ARE--(1) PARAMETERS OF VOWEL PERCEPTION, (2) RELATIONS AMONG RESPONSE RATE, TOPOGRAPHY, AND SCHEDULES OF REINFORCEMENT--METHODS AND FINDINGS IN AN ANALYSIS OF THE VOCAL OPERANT, (3) FOREIGN ACCENT AND…

This document contains information assembled by the Civil Engineering School to meet the initial requirements of NEPA 1969 and Executive Orders which required the Air Force to implement an effective environmental protection program. This course presents the various aspects of Air Force environmental protection problems which military personnel…

Effective ways to teach the science of acoustics to non-engineering students are presented and discussed. Topics include the physics of sound, sound wave phenomena, and noise control. (MLH)
