Sound Insulation Effect And Material Selection Of PVC Panels

Sound insulation effect and material selection of PVC panels

Quiet in the chaos, this is the life that many people yearn for. Both the convenience in the urban area and the quietness in the suburbs, so how can we achieve this? my country's regulations: The environmental noise limit of five types of urban areas: sanatorium, villa area, hotel area, 50dB (decibel) during the day, 40dB at night (referring to 22:00 to 6:00 the next day, the same below); for residential, cultural and educational institutions The main area is 55dB during daytime and 45dB at night; residential, commercial, and industrial mixed areas: 60dB during daytime and 50dB at night; industrial zone: 65dB during daytime and 55dB at night. But in life, we often can't really avoid these decibels. At this time, the appearance of PVC panels has solved this trouble for us.

The so-called PVC panel sound insulation, there are several situations: if the average sound insulation of the objective volume is less than 30 decibels, but the normal conversation sound next door can be heard clearly and the content of the conversation is easy to understand, then the sound insulation effect is very poor. If a loud conversation at 30~35 decibels can be heard quite clearly, normal conversation can be heard, but it is not easy to understand, then the sound insulation effect is very poor.

In the case of 40 to 45 decibels, loud conversations can be heard about, but not fully understood, and normal conversations cannot be heard. The sound insulation effect is better. If you can't hear loud conversations at 45~50 decibels, but you can only hear loud shouts and loud radios, then the sound insulation effect is good. Can score a 60 points. If you can't hear loudly yelling at 50~55 decibels, and you can't hear the loud sound of the radio, then the sound insulation effect is considered to be excellent. It can be used as a standard to judge the sound insulation effect of PVC panels.
