Optimal acoustic conditions in classrooms

The Journal of the Acoustical Society of America, 1999
Computer models of eight classrooms were constructed with varying combinations of absorbent materials on the surfaces of the rooms using the CATT 7.0 computer program. The amount, location and cost of finish materials and the noise levels produced by the air-conditioning system were varied in the models.

Classroom acoustics in green schools.

The Journal of the Acoustical Society of America, 2008
Green schools are becoming increasingly common as school districts continue to experience a rapid growth in population. These schools promote academic success and higher retention rates as well as healthier environments with cleaner air and more daylight as compared to their nongreen counterparts.

Classroom acoustics and vocal efficiency

The Journal of the Acoustical Society of America, 1999
The modern school classroom predicated upon the premise that effective vocal communication can take place. Such communication depends upon intact processes of speech production and reception. Numerous studies have demonstrated the inadequate acoustic conditions of classrooms and the impact of this situation on the reception of speech.

Acoustic Conditions for Speech Communication in Classrooms

Scandinavian Audiology, 1991
The purpose of this study was to measure reverberation times, background noise levels and Rapid Speech Transmission Index (RASTI) values in occupied and in unoccupied classrooms. Probability distributions of sound levels were also measured during classroom instruction.

Acoustics in the public school classroom

The Journal of the Acoustical Society of America, 2008
As mentioned in a DAGA 07 paper 1, physical science preparation in American schools often leaves something to be desired. In recent years the ASA Committee on Education in Acoustics has made an effort to participate in finding relief for that problem. Three approaches have been of some influence. 1. Teacher workshops; 2. Hands-on student sessions.

Speech intelligibility under realistic classroom acoustics

The Journal of the Acoustical Society of America, 2017
Speech recognition is fundamental in everyday communication environments, especially in school classrooms where the teaching-learning process takes place. Extensive literature is available that refers to speech intelligibility studies on the effect of artificially added reverberation and speech-shaped noise, whereas there is a little number of works ...

Classroom acoustics and children's speech perception

The Journal of the Acoustical Society of America, 2017
Children must learn in classrooms that contain multiple sources of competing sounds. While there are national standards aimed at creating classroom environments that optimize speech intelligibility (e.g., ANSI/ASA 2010), these standards are voluntary and many unoccupied classrooms fail to meet the acceptable levels specified. Moreover, little attention

Acoustic-phonetics demonstrations for classroom teaching

The Journal of the Acoustical Society of America, 2020
Physical demonstrations using vocal-tract models have been shown to be a quite intuitive way to teach acoustic phenomena on speech production for acoustic phonetics and speech science classes. Several models for different purposes have been developed by Arai within the last 20 + years, including vocal-tract models, sound sources, and lung models [e.g.,

Acoustics in the elementary classroom

The Journal of the Acoustical Society of America, 2005
The need for increased science exposure at all educational levels continues to be acute. Science is almost universally perceived as difficult, and its ability to raise the quality of life in the presence of apparently insurmountable social problems is increasingly suspect.
