How to Determine the Quality of Lightweight Soundproofing Board?
 In schools, residential dwellings, commercial office buildings, and other structures, there are high demands for sound insulation, fire resistance, and earthquake resistance. Creating a quiet environment is a pursuit for many. Xinjiang lightweight partition board manufacturer states that lightweight sound-insulating boards are "a must." So, how can one judge the quality of sound-insulating board's soundproofing effect?
If the average sound insulation level is objectively measured at less than 30 decibels, yet the conversations taking place in the adjacent room are clearly audible and easily understandable, the sound insulation is very poor.
If loud talk can be heard quite clearly at 30 to 35 decibels, and normal conversation can be heard but is not easily understood, then the sound insulation effect is poor.
At 35~40 decibels, loud speaking can be heard but not particularly clearly; normal conversation is very faint when heard, and the sound insulation effect is average.
At 40 to 45 decibels, loud conversation can be heard but not fully understood; normal conversation is inaudible. The sound insulation effect of lightweight隔音wall panels is quite good.
If loud talking is inaudible at 45 to 50 decibels, and loud shouting or a radio turned up to a high volume can only be faintly heard, the sound insulation is good. You can give it a 60 out of 100.
6. A loud shout is inaudible below 50 to 55 decibels, and radio at a high volume is also inaudible; only then can the sound insulation be considered excellent.
