The content of indoor acoustic design includes the selection of body size and volume, the selection and determination of the optimal reverberation time and its frequency characteristics, the combined arrangement of sound-absorbing materials and the design of appropriate reflecting surfaces to reasonably organize the near-reflection sound, etc.
Two aspects should be considered in the acoustic design. On the one hand, the effective sound reflection in the sound transmission path should be strengthened, so that the sound energy can be evenly distributed and diffused in the building space. loudness. On the other hand, various sound-absorbing materials and sound-absorbing structures should be used to control the reverberation time and specified frequency characteristics to prevent echoes and sound energy concentration. In the design phase, an acoustic model test is carried out to predict the effect of the adopted acoustic measures.
To deal with indoor sound quality in architectural acoustics, on the one hand, it is necessary to understand the influence of the shape of the indoor space and the selected materials on the sound field. It is also necessary to consider the relationship between the acoustic parameters of the indoor sound field and the subjective listening effect, that is, the subjective evaluation of the sound quality. It can be said that the quality of indoor sound quality is ultimately determined by the subjective feelings of the audience. Inconsistency in subjective evaluation is one of the hallmarks of this discipline due to differences in the individual feelings and tastes of the audience; therefore, architectural acoustics measures as research. It is also an important part of room acoustics to explore the correlation between acoustic parameters and the subjective perception of listeners, as well as the means of the relationship between the subjective perception of indoor acoustic signals and indoor sound quality standards.
