This project was the ceiling acoustic transformation of the outpatient hall of a large general hospital. The original mineral wool ceiling had poor sound absorption effect and was easy to sag and deform after long-term use. The outpatient hall has a large flow of people and many equipment, with noisy environment, which is not conducive to patient rehabilitation and medical staff work. As a high-standard medical place, it also has strict requirements on fire protection, moisture resistance and hygiene of ceiling materials.
After full demonstration, fiberglass acoustic ceiling panels were selected for overall ceiling replacement. Made of inorganic high-density glass fiber, the panels have inherent Class A fire resistance, low smoke and non-toxicity, fully complying with the strict fire safety codes of medical buildings. The interconnected porous structure has an ultra-high NRC of 0.90–0.95, which can effectively absorb the noisy crowd and equipment background noise in the outpatient hall, and create a quiet and peaceful medical environment.
At the same time, the panels have excellent moisture resistance and mildew resistance, are easy to clean and disinfect, and adapt to the high-hygiene use requirements of the hospital. The dimensional stability is strong, and it will not sag or deform after long-term use, reducing later maintenance costs. After the project was put into use, the ambient noise of the outpatient hall was significantly reduced, the patient’s medical experience was improved, and the work pressure of medical staff was also relieved. It has become a typical application case of high-performance acoustic ceilings in the medical field.
