Noise, screaming and shouting: Classroom acoustics and teachers’ perceptions of their voice in a developing country

South African Journal of Childhood Education, 2020
Background: The vocal demand on teachers may predispose them to vocal difficulties. This concern is exacerbated by unfavourable classroom acoustics and a large number of learners in a classroom in developing countries such as South Africa.

Toward realistic binaural auralizations – perceptual comparison between measurement and simulation-based auralizations and the real room for a classroom scenario

Acta Acustica, 2021
In order to make full use of their potential to replace experiments in real rooms, auralizations must be as realistic as possible. Recently, it has been shown that for speech, head-tracked binaural auralizations based on measured binaural room impulse ...

Study on Chinese Speech Intelligibility Under Different Low-Frequency Characteristics of Reverberation Time Using a Hybrid Method [PDF]

Archives of Acoustics, 2023
Reverberation time (RT) is an important indicator of room acoustics, however, most studies focus on the mid-high frequency RT, and less on the low-frequency RT.

Effects of noise and reverberation on speech perception and listening comprehension of children and adults in a classroom-like setting

Noise and Health, 2010
The effects of classroom noise and background speech on speech perception, measured by word-to-picture matching, and listening comprehension, measured by execution of oral instructions, were assessed in first- and third-grade children and adults in a ...

Acoustic Measurements in School Classrooms [PDF]

The Journal of the Acoustical Society of America, 1957
Acoustic measurements were made in the classrooms of twenty-two different school buildings in a study sponsored by the Acoustical Materials Association. Interior acoustical treatments in the rooms included full ceiling treatment, peripheral treatment, and no treatment.

Effects of noise and acoustics in schools on vocal health in teachers

Noise and Health, 2015
Previous studies on the influence of noise and acoustics in the classroom on voice symptoms among teachers have exclusively relied on self-reports. Since self-reported physical conditions may be biased, it is important to determine the role of objective ...
