Noise Reduction in Hospitals: Safeguarding Tranquility and Recovery
2025-11-04
During hospital construction, high-quality soundproof materials and doors/windows were used to effectively block external noise. The hospital provides "noise reduction education" for medical staff and patients, reminding them to speak softly and handle items gently in the hospital environment, especially in wards and rest areas, through training and public awareness campaigns. Community...
How to control noise in industrial workshops?
2025-11-04
Noise generated by mechanical equipment can be reduced through the following measures: 1. Select low-noise equipment: When purchasing equipment, priority should be given to equipment with lower noise levels. 2. Optimize factory layout: Plan the factory layout rationally, keeping noisy equipment as far away as possible from workers' work areas to reduce the direct impact of noise on workers...
