Hear the World Survey Reveals Underestimated Impact of Noise in the Classroom

 

Just in time for back to school, an international study conducted by Hear the World shows that noise levels in the classroom have a considerable impact on a child’s physical health and academic performance. The study, which surveyed just short of 500 schoolchildren in Germany, France, Italy, UK, Switzerland and the United States, found that the students reported feeling distracted, irritated and stressed by high levels of noise during class.

Beyond the potential for premature hearing loss due to continuous exposure to loud noises in the classroom, the study revealed that noise coming from the inside and outside of the class ranked high as a reason why students might be having trouble concentrating (6.5 on a scale of 10). In addition, other negative effects of a loud classroom were feelings of stress (5.4), headaches (5.1) and a growing level of aggression (4.6).

Hearing Loss and Academic Performance
If noise levels within the classroom are not lowered appropriately, or if a hearing loss is left undiagnosed, the potential consequences are often underestimated – significantly impacting not only a student’s academic performance, but also their emotional growth. With an average noise level in the classroom of 60 decibels, children struggle to understand their teachers, whose voice is measured at an average 65 decibels. With such strong background noise, it is challenging for students with and without hearing loss to follow discussions in class. As a result, students soon find their attention slipping and their motivation decreasing.

 

 

Quanto maiores as turmas maior o ruído, a intensidade do ruído e o tempo de exposição ao ruído, com as consequências que daí advêem.
