In industrial production, noise pollution that affects nearby residents often leads to complaints, rectification efforts, and even work stoppages.
Today, we’re sharing a real-life case from a machinery factory in Sanshui, Foshan: Faced with resident complaints, the factory used Shangcheng 50mm thick sound insulation panels (single-sided double-row perforated panels) to directly soundproof the inner walls of the workshop, and the results were well-received by all parties.

Project Background: Residents complain about equipment noise.
The machinery factory, located in Sanshui District, Foshan, primarily manufactures mechanical equipment. The workshop contains several high-noise machines such as punch presses and cutting machines.
Due to the factory’s proximity to residential areas, the noise generated by the equipment has drawn numerous complaints from nearby residents, putting the factory under pressure to implement environmental regulations. The factory manager stated, “We don’t want to shut down or relocate, and we hope to resolve the noise issue as soon as possible to give the residents an explanation.”

Solution: SAMZOON 50mm Thick Sound Insulation Board, Directly Adhesive to Walls
At the recommendation of the engineering company, the factory selected Shangcheng sandwich panel’s 50mm thick sound insulation board (single-sided double-row perforation), which was directly adhered to the inner wall of the workshop.
Why choose this product?
- 50mm thickness: Sturdy structure, providing sufficient sound insulation.
- Single-sided double-row perforation design: Enhances sound absorption, especially effective against mid-to-high frequency noise from equipment such as punch presses and cutting machines.
- Direct wall application: Does not occupy extra workshop space, simple and quick installation.
- No need to modify existing walls: Reduces the difficulty and cost of renovations.
Construction method
The factory does not alter the original building structure; instead, Shangcheng sound insulation panels are directly adhered to the inner walls of the workshop, forming an additional soundproof enclosure layer.
The engineering company is responsible for material procurement, while Shangcheng provides the products as the raw material supplier and does not participate in on-site installation.
Project results: Noise levels significantly reduced, and resident complaints ceased.
After installation, noise transmission from the workshop’s exterior walls was significantly reduced.
The factory manager reported, “After installation, we specifically went to the residential area to listen, and the sound was indeed much quieter. We haven’t received any further complaints since.” The engineering company also stated, “SAM ZOON’s 50mm thick sound insulation panels are of uniform size, making installation directly onto the wall very convenient, and the client is very satisfied with the results.”

Key product parameters (for engineering companies’ reference)
- Product Name: 50mm Thick Sound Insulation Board (Single-sided Double-row Perforation)
