A closed corridor, stair hall and classroom building between the ceiling NRC = 0.4. The hospital entrance hall, registration hall, pharmacy waiting hall and branch waiting hall, room floor, outpatient building corridor ceiling noise reduction coefficient NRC = 0.4. medicine Hospital health requirements, recommended micro perforated metal plate. Shopping malls, shops, shopping center, exhibition center, corridor ceiling NRC = 0.6 (high absorption standard) / 0.4 (low acoustic standard). Restaurant, fitness center, entertainment ceiling NRC = 0.8 (high absorption standard) / 0.4 (low acoustic standard). The cinema main speaker behind the end wall group NRC = 0.6. The hotel corridor sound absorption material NRC = 0.4. A large office ceiling decoration materials should be combined with sound absorbing material with NRC = 0.4. The meeting room wall and ceiling should be combined with the sound-absorbing material decoration materials using NRC = 0.4. |
