Evaluation of acoustical conditions for speech communication in active elementary school classrooms
نویسندگان
چکیده
Detailed acoustical measurements were made in 41 active elementary school classrooms near Ottawa, Canada to obtain more representative and more accurate indications of the acoustical quality of conditions for speech communication during actual teaching activities. This study found: a mean speech-to-noise ratio in active classrooms of 11dBA, reverberation times from 0.3 to 0.6 s that were not related to noise levels, and the effects of children on acoustical conditions.

The intelligibility of speech in elementary school classrooms.
This is the second of two papers describing the results of acoustical measurements and speech intelligibility tests in elementary school classrooms. The intelligibility tests were performed in 41 classrooms in 12 different schools evenly divided among grades 1, 3, and 6 students (nominally 6, 8, and 11 year olds). Speech intelligibility tests were carried out on classes of students seated at th...
متن کاملPercentage Articulation Loss of Consonants in the Elementary School Classrooms
Speech intelligibility was investigated by using directional source with its directivity similar to human condition for grades 2, 4 and 6 children in 27 elementary classrooms from 9 different elementary schools in Guangzhou. Objective acoustical measurements were also performed in these classrooms. The percentage articulation loss of consonants (%Alcons) was calculated from reverberation time (...
متن کاملRelationships between unoccupied classroom acoustical conditions and elementary student achievement measured in eastern Nebraska.
Building standards recommend maximum background noise levels (BNL) and reverberation times (RT) for unoccupied classrooms. However, existing research does not show a consistent correlation between these parameters and student achievement. Through in situ testing, this research seeks to determine what acoustical conditions should be attained in elementary schools for students to meet educational...
متن کاملEffects of classroom acoustics on performance and well- being in elementary school children: A field study
Children are more impaired than adults by unfavorable listening conditions such as reverberation and noise. Nevertheless, the acoustical conditions in classrooms often do not fit the specific needs of young listeners. This field study aimed to analyze effects of classroom reverberation on reading abilities, annoyance due to indoor noise, and school attitudes in second graders. Performance and q...
متن کاملSubjective and objective assessment of acoustical and overall environmental quality in secondary school classrooms.
A subjective survey on perceived environmental quality has been carried out on 51 secondary-school classrooms, some of which have been acoustically renovated, and acoustical measurements were carried out in eight of the 51 classrooms, these eight being representative of the different types of classrooms that are the subject of the survey. A questionnaire, which included items on overall quality...
