Background
Theaters are special buildings for performances such as dramas, create excellent performance environments for actors, create excellent auditory effects for audiences, and have very high requirements on acoustic effects.
Noise is classified into two major categories, fluid noise and mechanical noise. A large number of mechanical devices and pipelines with strong power, such as fans, air conditioning units, water pumps and the like, are generally installed in the building engineering, the noise generated by the operation of the devices contains the two types of noise, and the sound intensity of the noise is higher. Noise propagation is divided into air sound propagation and structure-borne sound propagation. The carrier that the air sound spreads is the air, and the ability of insulating the air sound mainly depends on the sound insulation volume of wall or wall, follows the law of quality, and the bigger the surface density is, the better the sound insulation effect is. The structure-borne sound transmission is a transmission mode in which a vibrating object directly impacts structures such as floors, walls and the like to generate vibration and transmit noise into a room along the structures. The theater building also comprises special equipment such as stage machinery, a car platform system, a scene system, a lighting system, a sound system, a curtain machine system, a control system and the like on the basis of possessing general building equipment, and if special silencing treatment is not carried out, the watching experience of audiences can be greatly influenced.
