Acoustics has become increasingly important in recent years. However, research has been carried out on this subject for many years. This is particularly the case for the acoustics of a classroom. We will see in this article :
Since the 1990s, various studies have been conducted on the subject of acoustic treatment. Some are specific to health issues, and others are specific to concentration and performance. Let’s take a look at these studies.
An association, the JNA, carries out an annual barometer on the impact of noise at work. Here are some conclusions:
These consequences apply to students and school staff.
Noise also affects concentration and performance. Researchers such as Banbury, Berry and Gonzalez have studied the subject. Here is some information on this work:
Noise is therefore a significant factor in improving concentration and performance.
We have already discussed the subject of acoustic regulation in another tutorial. Please read it to get an idea of how many decibels a classroom can emit and what the law says.
Most acoustic panels on the market are made of controversial materials such as glass wool or rock wool. Please be aware that these materials have been classified as “carcinogenic”. Studies have even shown that they are more dangerous than asbestos. Nevertheless, these materials are strangely classified as “A+” in terms of VOC emissions. This means that they would not be hazardous to air quality. Since some large companies use them massively, lobbying is most likely the answer to this question.
Aware of the risks to human health, we have therefore developed various laminates that only use materials that are not the subject of any such controversy. In addition, our Mutum ECO range includes products assembled using 100% recycled and recyclable materials. We therefore offer acoustic products with the lowest environmental impact on the market.
We thus use materials and techniques such as :
It all depends on the room in question. As explained in our tutorial on how to reduce noise in a room, the acoustics are influenced by different elements:
Thus, each room will require a specific acoustic study in order to determine the optimal treatment to be carried out in order to achieve the desired objective.
In the acoustic treatment of a classroom, voice frequencies will be the most important to be treated. Indeed, they are the ones that are disturbing for this type of environment.
Depending on the room, 3 types of treatment are possible:
Acoustics being a relatively complex science, we accompany you on your project according to different formats of acoustic services. In particular, we offer :
