The Importance of Good Sound Absorption in Schools

Acoustic Absorption in Schools

 

Improves Concentration

When students can clearly hear what the teacher is saying, they stay more focused for longer. This leads to students contributing more to class discussions and being more interested in the lesson. The pupils can also communicate easily with the teacher without the teacher needing to ask them to repeat themselves, which can undermine confidence.

 

Reduces Stress

Irritating background noise is very stressful for both the teacher and the pupils and it leads to tension and stress which is not conducive to a good learning environment. A good absorber will reduce this background noise by several decibels which is clearly beneficial for all. The teacher should be more relaxed and calm and this will reflect positively on the students. Also some students with learning difficulties get very tense in a noisy situation so very good sound absorption is critical in their learning environment.

 

Enables More Effective Group Sessions

Modern teaching methods encourage group work and this could lead to a very noisy classroom if noise is bouncing off all the room surfaces. It is natural in noisy situations to raise one’s voice in order to be heard and this just escalates when everybody raises their voice. A room with good acoustics will mean that much of this noise will be absorbed and so people will not need to talk so loudly. This should help prevent teachers from losing their voices too which can result in absences from work which increases the schools’ costs.

 

Enhances Good Behaviour

Students get bored and lose attention when they cannot clearly hear what the teacher is teaching. This often leads to bad behaviour which disturbs the whole class and will probably increase the teacher’s stress levels. The teacher will also lose valuable teaching time having to reprimand poor behaviour, and it can often be quite difficult to pinpoint the culprit in a noisy classroom.
