When choosing sound insulation panels, check if the product has a testing report. Different materials have varying sound insulation effects, and their performance is difficult to assess visually before construction.
When purchasing, pay attention to whether the sound insulation panels have a testing report issued by an authoritative laboratory. For domestic sound insulation testing, verify the testing organization's qualifications. Reports issued by testing institutions and laboratories authorized by the China Metrology Accreditation (CMA) and the China National Accreditation Service for Conformity Assessment (CNAS) are more reliable. The China Building Materials Testing Center and the Tsinghua University Building Environment Testing Center are considered authoritative in the testing field. When purchasing, also pay attention to quantitative indicators of sound insulation performance, such as sound insulation coefficient (STC), and note the impact of material density and installation sealing on the sound insulation effect.
If the sound insulation panel only provides a principle description without an authoritative testing report, careful evaluation is necessary before purchasing.
Damping sound insulation panels are a type of constrained damping structural panel, consisting of two building panels sandwiching a polymer damping material. Their sound insulation principle mainly relies on the conversion and consumption of sound energy by the damping layer, thereby reducing transmitted sound energy and increasing sound insulation. Meanwhile, this composite structure helps to reduce the fit effect of the panels.
The market price of sound insulation panels varies depending on factors such as materials, performance, and brand.
For different application scenarios, such as residential partition walls, KTV rooms, or hospital wards, appropriate sound insulation materials and construction solutions can be selected.
When purchasing, combinations of sound insulation felt and sealant can also be considered, and the long-term durability of the materials should be taken into account.
