THE MAIN SPACE IS DIVIDED INTO THREE LEARNING AREAS, PRACTICAL ARTS, ADMINISTRATIVE, AND COMMONS. FLEXIBLE PARTITIONS AND MOBILE CHALKBOARDS ACT AS VISUAL BARRIERS TO LIMIT DISTRACTIONS WHILE CARPETING AND ACOUSTIC BAFFLES…

Information concerning the following considerations in the selection of carpeting for educational facilities is given--(1) characteristics of face yarns, pile, backing and underlayment, (2) carpet construction, (3) acoustical properties, (4) heat transfer properties, (5) fungistatic and bacteriostatic characteristics, (6) cost, and (7)…

Two experiments were conducted to assess the correlations of residue features with some perceptual properties of voice disorders. Results suggested that residue features may be useful in assessing the degree of vocal impairment, but use of residue features as correlates of voice quality requires further research. (Author/DB)

Explains how to use the equation for frequency of vibration of a transversely oscillating bar or pipe with both ends free to vibrate to build a simple and inexpensive xylophone from a 3-meter section of copper pipe. The instrument produces a full major scale and can be used to investigate various musical intervals. (Author/NB)
