Performing arts buildings include various types of cinemas, theaters, theaters, audio-visual rooms, exhibition rooms, studios, recording rooms, and other multi-purpose hall buildings.
With the rapid development of the economy and the continuous improvement of people's living standards, after meeting the basic guarantee of material life, people begin to pursue spiritual sustenance and aesthetic pleasure, which is called spiritual life. In the continuous progress of society, more and more middle and upper class members are emerging, many of whom belong to the group pursuing high-quality consumption. The development of performing arts architecture has enabled a large number of social groups to relax and enjoy themselves in today's fast-paced and high-pressure society.
To build a comfortable performing arts building environment, not only does it require a grand or gorgeous appearance, but also the indoor acoustic environment must be considered. The scope of performing arts architecture is relatively broad. Below, we will analyze the acoustic design of some of the main venues.
A recording studio, also known as a recording studio, is a specialized recording venue built by people to create specific acoustic conditions for recording. It is a recording venue for movies, songs, music, etc. The acoustic characteristics of a recording studio play a very important role in the quality of recording production and its products. People can classify it according to their needs, for example, according to the basic characteristics of the sound field, it can be divided into natural reverberation recording studios, strong absorption (short reverberation) recording studios, and active quiet end (LEDE) recording studios. It can also be divided into white recording studios, music recording studios, sound recording studios, mixed recording studios, and so on from a usage perspective.
The acoustic design specifications require that the sound quality of the recording studio should mainly be "high language clarity and intelligibility, followed by good fullness". Under the main usage conditions, it should have corresponding reverberation time and frequency characteristics to the pickup requirements, and suppress sound defects that affect the pickup audio, such as echoes, trembling echoes, low-frequency buzzing, etc. According to the above requirements; The design standards for the recording studio are:
The recording studio uses short reverberation, and the appropriate reverberation time should be selected based on the indoor volume. The frequency characteristics of the reverberation time should be flat. Acoustic technical indicators:
Recording room acoustic indicators
The noise in the recording studio comes from multiple sources. The noise from outside the recording studio can be mainly divided into two categories: one is the traffic noise generated by passing vehicles, airplanes, etc. outside the recording studio building; Another type of noise comes from inside buildings but outside the recording studio, such as loud conversations and noise during commuting; There is also internal noise from the recording studio, mainly from the air conditioning system, lighting control system, and the movement noise of the camera and the walking noise of the staff during the operation of the recording studio.
Noise enters the recording studio mainly through three ways. Firstly, noise acts on walls, floors, and ceilings, causing vibration and radiating sound energy into the recording studio; The second is to transmit sound into the recording studio through air through gaps and unsealed holes left during construction; The third is to enter the recording studio through solid sound transmission through the rigid connection between the wall, roof, or ground of the recording studio and the outside world.
The sound insulation problem of the recording studio mainly involves the surrounding walls, windows, and entrance and exit doors.
The following methods are mainly used for sound insulation of the above issues:
Mainly lies in the use of multi material composite sound insulation walls with different sound insulation levels (multi damping lightweight wall sound insulation) and external window sealing, which can basically isolate the impact of external noise on the recording studio; The entrance and exit doors should use composite material national standard soundproof doors.
