“…This finding is in concordance with previous studies that have shown that road traffic and aircraft noise interferes with speech and teaching inside classrooms since external high noise levels may influence internal noise levels. [ 11 42 ] Therefore, lower RTs and lower noise levels are important elements to consider in the design of schools in order to reduce voice disorders among teachers. It is recommend to take into account the location of school buildings and sound insulation of the building when planning their construction, since it seems that external high noise levels have important effect on internal noise levels and thus on vocal health in teachers.…”

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 measurements of noise and acoustics in the presence of voice symptoms. To assess the association between objectively measured and self-reported physical conditions at school with the presence of voice symptoms among teachers. In 12 public schools in Bogotá, we conducted a cross-sectional study among 682 Colombian school workers at 377 workplaces. After signed the informed consent, participants filled out a questionnaire on individual and work-related conditions and the nature and severity of voice symptoms in the past month. Short-term environmental measurements of sound levels, temperature, humidity, and reverberation time were conducted during visits at the workplaces, such as classrooms and offices. Logistic regression analysis was used to determine associations between work-related factors and voice symptoms. High noise levels outside schools (odds ratio [OR] = 1.83; 95% confidence interval [CI]: 1.12–2.99) and self-reported poor acoustics at the workplace (OR = 2.44; 95% CI: 1.88–3.53) were associated with voice symptoms. We found poor agreement between the objective measurements and self-reports of physical conditions at the workplace. This study indicates that noise and acoustics may play a role in the occurrence of voice symptoms among teachers. The poor agreement between objective measurements and self-reports of physical conditions indicate that these are different entities, which argue for inclusion of physical measurements of the working environment in studies on the influence of noise and acoustics on vocal health.

“…In addition to deleteriously affecting speech recognition, background noise can also compromise academic performance, reading and spelling skills, concentration, attention, and behavior in children (Ando & Nakane, 1975;Crook & Langdon, 1974;Dixon, 1976;Green, Pasternak, & Shore, 1982;Ko, 1979;Koszarny, 1978;Lehman & Gratiot, 1983;Sargent, Gidman, Humphreys, & Utley, 1980). Koszarny (1978) reported that noise levels tend to affect concentration and attention more seriously in children with lower IQs or high anxiety levels.…”

“…Classroom noise has also been shown to affect teacher performance (Crook & Langdon, 1974;Ko, 1979;Sargent et al, 1980). For example, Ko (1979) obtained information from more than 1,200 teachers concerning the effects of noise in the classroom. Results indicated that noise related to classroom activities and traffic or airplane noise were correlated with teacher fatigue, increased tension and discomfort, and an interference with teaching and speech 1 A similar concept to NC curves is room criteria (RC) curves.…”

Past investigations demonstrate that the acoustical environment of a classroom is a critical factor in the academic, psychoeducational, and psychosocial achievement of children with normal hearing and with hearing impairment. This article examines several acoustical variables, such as noise, reverberation, and speaker-listener distance, which can deleteriously affect speech perception in classrooms. Moreover, the discussion examines the effects of these variables on the speech perception abilities of both children with normal hearing and children with hearing loss. Finally, appropriate acoustical criteria are suggested for children in educational settings.

“…The results of Bradley [6] tend to suggest that these indices are highly correlated with each other, implying that they are in principle equivalent for the purpose. The speech intelligibility is affected by the background noise, but the noise exposure of the children and teachers has been shown to have other additional impacts on the teaching and learning process [7,8].…”
