How to achieve efficient sound conditioning in schools?


Noise reduction in educational facilities can pose a considerable challenge, depending on the specific conditions on site. Noise in the classroom doesn't even have to come from the pupils or students themselves. Other noise sources, such as activities in adjacent rooms, the schoolyard or the corridor, may actually be the main disruptive factor. And in schools located on a busy street, the noise generated by traffic or, as the case may be, a building site can massively disrupt lessons.

High noise levels in school facilities can negatively affect the ability to concentrate and the well-being of students and teachers. In addition, poor acoustics and/or high reverberation in the classroom or other rooms can prevent students from hearing the teacher properly, resulting in misinterpretations and confusion. Headaches, too, are a common effect of exposure to constant noise.

This shows that noise protection is an important factor that schools should definitely take into account in order to create an optimal learning environment. So what can be done to implement effective noise control in schools and improve the acoustic conditions in the classroom?

soni HEXAGON
soni HEXAGON is a hexagonal acoustic element for sound absorption and optimizing the acoustic conditions in buildings. It consists of a white polyester non-woven, laminated with a decorative felt layer in modern trend colors. Designed for wall mounting, the geometric noise-absorber shapes are available in two different thicknesses – for customized interior design in line with your concept and ideas. For a significant improvement of the room's acoustics, we recommend lining 30 to 50% of the ceiling/wall surface with sound absorbers, preferably evenly distributed across the room for the best result. By minimizing sound reverberation, soni HEXAGON lowers the overall noise level and improves speech intelligibility, making your office, call center, entrance area or conference room a much more pleasant place to stay.soni HEXAGON fulfills the fire safety standards set down in DIN EN ISO 13501 and DIN 4102 (flame-retardant) for the building sector. This means you can use soni HEXAGON absorbers as an attractive and functional wall decoration wherever you need to lower the noise level with materials that meet strict fire safety regulations.For fastening soni HEXAGON absorbers on smooth and clean surfaces, we recommend our soni SPECIAL ADHESIVE. If you do not wish to use glue on a large surface area, we suggest using our soni VELCRO TAPE as an alternative fixation method.

soni PORTA
Effective and comfortable door insulation with soni PORTA Earsplittingly loud music from your teenager's room, bothersome noise from the hallway, loud phone conversations from the adjacent office, lack of discretion in treatment rooms - wherever closed doors are supposed to provide undisturbed quiet, our door insulation kit is the ideal solution for effective noise reduction.Our soni PORTA solution consists of six precisely fitting elements that form an attractive pattern and are simply glued to the door using the two included installation aids and our easy-to-understand installation instructions. Thanks to our unique, protected self-adhesive solution, you can remove soni PORTA again from smooth surfaces without leaving any residue, if necessary, for instance when moving out.Elegantly shaped cutouts for the door handle, on the left or right as needed, complete the sophisticated design.Depending on the application, the material has to be mounted either on the inside or on the outside of the door. For this reason, soni PORTA has been designed in two standard heights. It is important to install the door insulation material always on the side of the noise source.soni PORTA is suitable for the sound insulation of any room door with rebate - in private homes as well as in day-care centers, kindergartens, schools, medical facilities, offices, hotels, banks, etc.The soni PORTA elements are made of a combination of two highly effective acoustic materials: a heavy layer and an acoustic foam layer. The heavy layer on the underside of soni PORTA is glued directly to the door leaf, increasing its mass and thus the overall sound insulation effect of the door. The visible side consists of an acoustic foam layer covered with an attractive felt material. The foam’s open cells absorb sound energy. The robust and dirt-repellent felt surface is available in trendy colors. The edges of the elements can be masked with our soni VLD adhesive tape, if desired.For ordering the soundproofing set that fits your door, you will need the outer dimensions of the door leaf. Please measure the width and height of your door leaf on the outside, i.e. on the side in the direction in which your door opens.Please note: If the gap between the door leaf and the floor is too wide, we recommend mounting a door sweep or a door bottom seal. Only when all gaps and openings around the door are closed, perfect soundproofing is possible. soni PORTA is also available in a version that is not removable without residue: soni PORTA Basic Important information on installing soni PORTA door insulation: Correct installation is crucial for soni PORTA to be fully effective: 1. unhinge the door before installation and place it in a horizontal position on a stable surface. 2. apply the individual insulation elements horizontally to ensure optimum adhesion of the adhesive. Do not apply when hanging! The weight of the integrated heavy film could cause the adhesive to come loose again (does not apply to soni PORTA Basic). 3. leave the door to rest for at least 24 hours after installation and only hang it up again the next day. This will ensure that the door insulation remains in place permanently and that optimum sound reduction is achieved!

What does efficient sound conditioning in schools look like?

Efficient sound conditioning in schools goes beyond simply reducing the noise volume during lessons. The aim of any acoustic measures in the classroom must be to create an acoustically pleasant atmosphere that supports studying. No two classrooms are exactly the same, every room has its own acoustic challenges that need to be taken into account when planning the right noise protection measures.

Regularly checking the acoustic conditions in your school can help you pinpoint potential noise issues as early as possible. A noise-control expert can help you to identify the causes of the high noise level and its sources.

Experts’ tip:
The newly developed room acoustics app from soniflex provides you with a helpful tool that allows you to take immediate action. Using your smartphone, you can easily measure the reverberation time in the classroom at various positions within the space. Once the measurements are completed (which takes only a few minutes and requires no acoustic knowledge) the app analyses the measured values and suggests suitable products in the required quantities. In the next step, you can put your favorite products in the shopping cart and order directly via our online store. Of course, we shall also be happy to prepare a non-binding custom-tailored offer. Simply contact us and tell us what you need.

Postscript: You can find the soniflex room acoustics app in the AppStore or in the Google Play Store, keyword "soniflex".

How to successfully implement acoustic measures in the classroom?

For the implementation of active noise control also in your school, the installation of sound-absorbing materials on walls and ceilings and the deployment of noise-absorbing objects are valuable and very efficient tools.

A recommended product for application to walls and ceilings is soni COLOR RD, for example. These square acoustic panels are available in different colors, they reduce reverberation and create a pleasantly quiet learning atmosphere.

Free-standing sound-absorbers such as soni CUBE can be a very practical addition to the classroom since they double as seating cubes. While they help reduce noise during lessons, you can also use them to create an inviting seating area for breaks or informal group work. Colorful shapes like our soni CIRCLE or soni HEXAGON or the cheerful soni ELEMENT animal shapes help improve the acoustic conditions and add to a warm and child-friendly classroom design at the same time.

With soni TRAPEZ you can not only create attractive geometric patterns on the ceiling, but above all ensure an effective improvement in room acoustics. The sound-absorbing elements are made of light-gray or white melamine foam and can be easily fixed to the ceiling using the special soniflex adhesive.
