What Is an Architectural Acoustic?

Architectural acoustics is the science that studies acoustic environmental issues in buildings. It mainly studies indoor sound quality and noise control of the built environment to ensure good listening conditions indoors.

Architectural acoustics is a discipline that studies the propagation of sound, evaluation and control of sound in the built environment.

Architectural acoustics was first recorded in the "Ten Books of Architecture" written by Roman architect Vitruvius in the first century BC. Gucci

Investigate the physical conditions and acoustic treatment methods of indoor acoustic wave transmission to ensure good listening conditions in the room; study and control noise interference and hazards in a certain space inside and outside the building. ^[1]

Architectural acoustic environment generally has two components:

The combination of sound-absorbing materials is arranged and an appropriate reflecting surface is designed to reasonably organize the recent reflection of sound and the like.

Acoustic design should consider two aspects. On the one hand, it is necessary to strengthen the effective sound reflection in the sound transmission path, so that the sound energy is 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 prescribed frequency characteristics, and prevent the phenomenon of echo and concentration of sound energy. Acoustic model tests are performed during the design phase to predict the effects of the acoustic measures taken.

Building air sound

In the Middle Ages, European churches used large interior spaces and walls with low sound absorption coefficients to produce long reverberations and create a mysterious religious atmosphere.

The basic task of building acoustics is to study the physical conditions and acoustic processing methods of indoor acoustic wave transmission. Therefore, modern building acoustics can be divided into

The hall building space is relatively large, so ^[3]

The subjective and objective aspects of indoor sound quality have not been completely resolved. The reverberation process plays an important role in all aspects of room acoustics, and it is the evaluation standard with the least debate when judging the sound quality of various rooms. However, the classic reverberation time formula has limitations, so research on the reverberation process is still underway, such as studying the characteristics of acoustic signals, analyzing the delay and repetition of basic signals generated by indoor acoustic reflections to improve the performance of different styles of programs, and exploring indoors. The relationship between the subjective sensation of the acoustic signal and the sound quality standard of the room. Computer simulations of indoor sound propagation are studied. Electroacoustic technology, especially the stereo reverb system, is used to control the sound quality of room music.

Since indoor acoustics is closely related to the volume, shape and interior surface treatment of the building space, the indoor acoustic design must determine the solution from the architectural point of view. Achieving a high degree of uniformity in acoustic functions and architectural arts is the common goal of cooperation between scientists and architects. To improve the acoustic environment of buildings, basic research, technical measures, and organizational management measures must be strengthened. Although the focus should be on sound sources, it is often difficult or impossible to change the sound source. Therefore, more attention must be paid to the propagation path and receiving conditions. . Various control technologies involve economic issues, so comprehensive research must be carried out in cooperation with relevant professionals to obtain the best technical results and economic benefits.

Architectural acoustics, as a branch of the discipline of architectural technology, is receiving more and more attention. The reason why architectural acoustics is valued is that it has a great relationship with the content of its research. Architectural acoustics mainly studies indoor sound quality and noise control in the built environment. In general, on the one hand, it is necessary to study how to ensure a good sound effect indoors, on the other hand, Reduce and control noise. ^[4]
