Noise reduction parameters are metrics used to evaluate and describe noise reduction effectiveness. The following are some common noise reduction parameters that can be used to evaluate the noise reduction performance of live streaming silent cabins:
STC (Sound Transmission Class): STC is an indicator that evaluates the sound insulation performance of a material or structure, indicating how well the material or structure blocks sound within a specific frequency range. Higher STC values indicate better sound insulation.
NRC (Noise Reduction Coefficient): NRC is an indicator that evaluates the sound absorption performance of a material, indicating its ability to absorb sound. Higher NRC values indicate better sound absorption, helping to reduce echoes and noise reflections.
CAC (Cost Acoustic Class): CAC is an indicator that evaluates the performance of soundproof doors, indicating their ability to resist sound penetration. Higher CAC values indicate better sound insulation.
NC (Noise Reduction Class): NC is an indicator that evaluates the noise level of a specific environment, indicating the noise level. Lower NC values indicate lower noise levels.
RT (Reverberation Time): RT is a metric that assesses the speed of sound decay within a space, representing the time it takes for a sound to decay from its peak to the background noise level. A lower RT value indicates a shorter reverberation time, which helps reduce echo and provide clearer sound.
These noise reduction parameters can be determined by testing and evaluating the performance of the materials, structure, and equipment of the live broadcast silent room. Specific noise reduction parameters should be evaluated based on the design and usage requirements of the live broadcast silent room to ensure that the noise reduction requirements are met.
