Installing sound-absorbing built-in ceilings in the classroom and laying carpets on the floor will give you good acoustics and reduce much reverberation time. This method is more economical for the construction of new classrooms and the renovation of existing classrooms.


For small and medium classrooms, if using a built-in ceiling whose NRC>0.75, its reverberation time is acceptable. Carpet has a certain absorption effect on high frequency noise, but mainly used to reduce the noise made by students. Unfortunately, this method has no effect on controlling the reverberation of the wall. However, if you deliberately arrange furniture such as cabinets and bookcases to divide the large and flat walls, it can also reduce the echo.


The best design for a lecture-style classroom is to move some of the sound-absorbing material from the ceiling to the wall, keep the center of the ceiling hard, To ensure that the teacher's words are reflected to the back of the classroom. This semi-absorbent, semi-reflective ceiling looks complicated, it can be built using standard compartments. You only need simply place the acoustic ceiling panel around the ceiling, and install gypsum board on the roof.


If you need to reflect more sound to the back of the classroom, the reflective surface of the ceiling can be set according to the position of the teacher at the front. This part of the reflective surface must be made of a sturdy material such as splint or gypsum board, and can be painted to harmonize with the entire house. Putting sound-absorbing materials into the wall also reduces reflections and eliminates echo.
