Optimal acoustic conditions in classrooms
The Journal of the Acoustical Society of America, 1999Computer 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.

Acoustical evaluation of preschool classrooms
The Journal of the Acoustical Society of America, 2003An investigation was made of the acoustical environments in the Berwick Preschool, Vancouver, in response to complaints by the teachers. Reverberation times (RT), background noise levels (BNL), and in-class sound levels (Leq) were measured for acoustical evaluation in the classrooms.

Acoustical analysis of preschool classrooms
The Journal of the Acoustical Society of America, 2018The present study explores acoustical parameters, including unoccupied and occupied noise levels and reverberation time (RT), in typical preschool classrooms located in the northern suburbs of Chicago. The study was motivated by the following observations: (1) preschool classrooms are often established in buildings that were not initially constructed ...

Classroom acoustics and vocal efficiency
The Journal of the Acoustical Society of America, 1999The 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.

Norwegian experiences of acoustics in classrooms
The Journal of the Acoustical Society of America, 2017During the last decades, the investments on new school buildings and retrofitting of existing buildings have been considerable in Norway and it will continue for the next years. A characteristic of this period have also been a development of the teaching methods and as a consequence of that, a change of the area planning and room layout, in the ...

Musical acoustics in the science classroom
The Journal of the Acoustical Society of America, 2001The value of hands-on laboratory centered teaching of science has led to continued workshops for elementary and secondary school teachers. Emphasis for teachers in the primary grades has been on the use of music as a tool to introduce science concepts, and for teachers at the secondary level to use computer based instrumentation to perform relatively ...

Acoustic Filter for Classroom Use
American Journal of Physics, 1955Many articles and text books have treated acoustic filters from various viewpoints, and acoustic filter experiments have been devised for laboratory courses in acoustics. These experiments frequently point out the analogy between lumped-constant acoustic filters and electrical filters, in order to make use of the many texts and handbooks dealing with ...
