Pain Point Analysis of Acoustic Insulation

According to the survey released by professional organizations, the current complaints about poor noise-proof effect accounts for about 35% of the total number of complaints from star-rated hotels. Appropriate acoustic design will create a comfort hotel environment and enhance the customer experience, thus directly affecting the rating and pricing standards of the hotel. The acoustic insulation design and sound leakage prevention of the rooms are the focus of the entire acoustic design. The ordinary Sauerland-board products cannot meet this standard.
