The acoustics in the classroom play a decisive role in pupils' learning success. Good room acoustics not only improve speech intelligibility, but also concentration and the well-being of everyone involved. But what exactly does good room acoustics mean, why is it so important and what requirements do classrooms need to fulfil in order to provide optimal acoustic conditions? Find out more in this blog post.

Effect of poor acoustics in classrooms

Poor acoustics in classrooms can have far-reaching negative effects on teaching and learning. In rooms with a long reverberation time and a high noise level, pupils have difficulty understanding the teacher clearly. This leads to increased cognitive strain as they have to work harder to follow what is being said. This is particularly problematic for younger children who are still learning to understand complex language structures, as well as for children with hearing impairments or non-German native speakers.

The consequences are reduced attention, faster fatigue and frustration, which in turn can lead to poorer learning performance. Poor acoustics can also put a strain on teachers' voices as they are forced to speak louder to make themselves heard. In the long term, this can lead to vocal problems and stress.

What are good room acoustics in the classroom?

Good room acoustics in the classroom are characterised by optimal speech intelligibility. This means that spoken words can be heard clearly and distinctly without disruptive reverberation or background noise interfering with communication. One of the most important acoustic parameters is the reverberation time, which should ideally be short enough to ensure intelligibility, but long enough to give the room a pleasant acoustic atmosphere.

The distribution of sound in the room also plays a role. Reflections from walls, ceilings and floors should be controlled in order to avoid so-called "flutter echoes", which make it difficult to hear. Acoustic measures such as absorbent ceilings, carpets or wall panels can help to dampen the sound and improve speech intelligibility.

This is where innovative solutions such as the Sonic panels from us come into play. These porous sound absorbers, specially developed for ceilings, effectively reduce reverberation times and ensure a balanced sound distribution in the room. By using these highly effective acoustic ceiling panels, classrooms can be optimally equipped to significantly improve both the learning conditions for pupils and the working environment for teachers.

Why are room acoustics important in classrooms?

The importance of room acoustics in classrooms lies in their direct influence on learning conditions. Good acoustics promote concentration, improve communication between teachers and pupils and contribute to a pleasant learning atmosphere. Particularly in schools where many pupils learn in a confined space, controlling the acoustics is crucial in order to avoid overlapping noises.

In addition, good room acoustics also have a social component. Inclusion and equal opportunities in education are closely linked to the ability of all pupils to follow lessons, regardless of their hearing ability or previous language skills. This applies in particular to pupils with hearing impairments or those whose native language is not German.

Basic acoustic requirements for classrooms

To ensure good room acoustics in classrooms, there are some basic requirements that should be taken into account:

• Reverberation time: The reverberation time in classrooms should ideally be between 0.4 and 0.6 seconds. This ensures good speech intelligibility and prevents the occurrence of disturbing reverberation.
• Noise level: The background noise level should be kept as low as possible. External noise sources such as traffic noise or loud heating systems should be minimised or shielded.
• Sound absorption: The use of sound-absorbing materials on ceilings, walls and floors can help to reduce sound levels and improve speech intelligibility. Sonic panels from Sager AG are an excellent solution to effectively fulfil these requirements.
• Room geometry and furnishings: The design of the room and the arrangement of the furniture can have a positive influence on the acoustics. Large, open areas should be avoided and instead complemented by a clever room layout and the use of sound-absorbing furniture.
• Sound distribution: An even distribution of sound in the room is important to ensure that all pupils can follow the lesson clearly, regardless of where they are sitting.

Conclusion

Good room acoustics in the classroom are not a luxury, but a necessity for successful teaching. It not only promotes pupils' understanding and concentration, but also contributes to teachers' well-being. Schools should therefore take acoustic requirements into account when planning and designing classrooms in order to create optimal learning conditions. With innovative solutions such as the Sonic panels from Sager AG can effectively solve acoustic problems and create a learning environment that benefits all pupils.
