Acoustics in Schools

Acoustics in schools has been a growing area of focus in recent years. In the past 30 years there have been many investigations examining the relationship between noise exposure of school children and their performance. The earlier studies were concerned mainly with external environmental noise exposure of schools, but more recently the effects of internal classroom noise have been investigated. It is generally accepted that noise has a detrimental effect upon the learning and attainments of primary school children.

Free Acoustic Survey for all Schools and Education Establishments

For all schools and education establishments Quietstone offer a free survey and report service to help you get the most of our products. Our Acoustics in Schools Free Survey involves doing acoustic calculations and listening to the requirements before going away and making a report which illustrates the amount and type of treatment you require and how much of a difference this will make. From here, you can choose to either go with our recommendations or pick from our catalogue which is made easy using our acoustic ‘points’ system awarded to each product.

Sports and multi purpose halls

Often, halls have to cater to a variety of functions including public speaking, group activities, music and sports. Each of these functions require acoustic consideration. In a large space with predominantly hard, reflective surfaces, reverberation can drastically reduce speech intelligibility and cause high noise levels.

Speech intelligibility in classrooms

Classrooms should now adhere specified reverberation times. These ensure that speech intelligibility is maintained for teaching and noise levels are controlled to provide comfortable acoustics and minimum distraction.

Positioning of absorption in classrooms

As well as applying a suitable amount of sound absorption, BB93 addresses the best ways to mount panels. The 2 pictures above show recommended positioning of absorption materials for good speech intelligibility. Both include back wall covering to avoid long, delayed reflections which reduces clarity but leave the ceiling largely uncovered to allow for early reflections which increase intelligibility.

Corridors, entrances and stairwells

Noise in corridors can be very disturbing to adjacent classrooms. It is therefore important to control reverberation in these spaces to reduce noise levels.
