As a learning place, the acoustic environment of the classroom will have an important impact on the teacher's teaching effect and students' learning efficiency. According to the requirements of the national acoustic standards, the ideal acoustic effect of the classroom should meet the conditions of having a higher language intelligibility, avoiding the occurrence of acoustic defects such as echo, multiple echo, and tremor echo.

In response to the main purpose of the school and the national attention and call for environmental protection, Guangdong Environmental Protection Engineering Vocational College plans to test and reform a classroom in the school, and the acoustic environment overall solution service provider TianGe Acoustics will customize the acoustics for the classroom Transformation plan.

According to the country's call, the talent strategy is a major, macro, and overall vision and arrangement for the cultivation, attraction, and use of talents by the state in order to achieve economic and social development goals and use talents as a strategic resource. As one of the main carriers of talent training, the acoustic construction of schools and classrooms cannot be ignored. TianGe Acoustics has always strongly supported the country's talent training strategy, and the implementation and cost of the classroom acoustic environment transformation program are strongly sponsored by our company!

The classroom is a medium-sized classroom in the teaching building of the college, with a building area of 96 square meters, a volume of 358m³, a floor height of 3.824m, 112 existing seats, and a brick wall structure. Mainly for teaching activities, and to meet the functions of large classes in class, class discussions, experimental demonstrations, holding competitions and class activities, so there are higher requirements for the sound quality environment of the classroom.

Tiange Acoustics combined with the actual situation of the classroom to formulate a transformation plan, with both good sound quality and space decoration as the starting point, and strive to make the classroom into a modern classroom that combines audio-visual enjoyment and beauty. To ensure that the decoration construction can be carried out quickly without affecting the normal classroom time of the classroom, the ceiling is regarded as the key acoustic decoration object.

As the largest complete plane in this space, smallpox has a high share of the entire surface area and has a great influence on the entire sound field. The arrangement of its sound absorbing materials cannot be ignored. Due to the low height of the original building and the low ceiling height, if additional sound-absorbing decorative layers are added, the height will be reduced, making the entire space too depressed. According to the size of the space and considering the acoustic effect, TianGe Acoustics directly hangs the Melamine Acoustical Foam on the ceiling, which will not pull down the height of the floor and will achieve better sound absorption.

The best installation method for on-site debugging of Melamine Acoustical Foam

Melamine Acoustical Foam is a patented product of Tiange Acoustics, the product has the following advantages:

1. Implement the current national industry standards

2. Good environmental performance, sanitation meets food grade hygiene requirements

3. The material burning performance level reaches B1 level

4. The quality requirements related materials meet the quality standards

5. Convenient processing, easy to cut, convenient construction and no dust pollution during construction

6. Volumetric weight: 8-20kg / m³

7. Compared with other sound-absorbing cotton boards, it has higher sound absorption performance, no dust pollution, no harm to human body.

The product sound absorption coefficient

After the acoustic transformation, the sound quality of the classroom has been significantly improved, and the decorative effect has also been significantly improved! The completion of this project has created a comfortable, beautiful and good sound quality learning environment for the teachers and students of Guangdong Environmental Protection Engineering College, and it has further strengthened Tiange Acoustic's determination to continue to help the national talent training strategy in the future!
