Acoustic decoration of multimedia classroom

The quality of sound insulation plays a very important role in multimedia decoration. Its quality fundamentally affects the acoustic effect of the multimedia classroom. Wall and wall construction treatment processes mainly include acoustic treatments such as sound insulation, noise reduction, and sound absorption. The current building thickness and sound insulation effect are generally difficult to meet the sound insulation requirements of the multimedia room, so the sound insulation treatment must be carried out on the basis of the sound insulation of the original wall, and then the acoustic effect treatment of the wall is carried out.
Acoustic treatment is to ensure the clarity of speech and the listening effect of the audience. When doing acoustic treatment, we must pay attention to the fact that the doors, windows, glass, seats, decorations and other facilities in each hall must not have resonance phenomena. Defects such as echoes, flutter echoes, standing room waves and acoustic focusing must not occur. The impact of reverberation time on acoustic quality is well known. If it is too long or too short, the audience will feel tired. Only an appropriate reverberation time can make the sound full and pleasant, and the language friendly and clear./
