Taking stock of the sound environment designs in hospitals

1. Spatial Planning and Functional Zoning

Reasonable space planning is the basis for creating a quiet environment. It is recommended to adopt a "three-level zoning" model:

1. Level 1 zoning: Completely separate the outpatient area, emergency area and inpatient area, and set up independent entrances and exits
2. Secondary zoning: Divide the nursing units within the inpatient department, with 40-50 beds per unit being appropriate
3. Level 3 zoning: The ward area adopts a single corridor layout, with the nurse station located in the middle to shorten the nursing distance

Scientific zoning can effectively reduce noise disturbance caused by the flow of people. Data shows that reasonable zoning can reduce noise in ward areas by 10-15dB(A).

2. Building sound insulation design

Building sound insulation is a key technical measure to ensure a quiet environment:

1. Wall: 200mm aerated concrete block + 50mm rock wool + 12mm gypsum board composite wall, weighted sound insulation RW ≥ 50dB
2. Floor: Floating floor is laid, and 5mm elastic pad is used to reduce the impact sound by 18dB
3. Doors and windows: Use professional soundproof windows with sealing strips, with a sound insulation RW ≥ 35dB, preferably with ventilation function

3. Indoor acoustic environment optimization

Improving indoor sound environment through acoustic design:

1. Sound absorption treatment: Mineral wool sound absorption panels are installed on the ward ceiling, with a sound absorption coefficient of α≥0.8
2. Background music: Play soothing music below 45dB in public areas to mask sudden noises
3. Sound field adjustment: Use adjustable sound absorbers to optimize the sound environment according to usage requirements

4. Intelligent noise control

Use modern technology to strengthen noise management:

1. Install a noise monitoring system to display the noise level in each area in real time
2. Use intelligent calling system to reduce the noise generated by manual calling
3. Equipped with mobile sound insulation screens to temporarily isolate noise sources

V. Management system construction

Perfect system protection is the key to maintaining a quiet environment:

1. Formulate a hospital noise management system and clarify noise limits for each area
2. Establish quiet hours (e.g. 12:00-14:00, 21:00-7:00) and strictly control visitation
3. Carry out training for medical staff to enhance awareness of noise prevention and control

VI. Humanized Service Measures

Reduce noise generation through humanized services:

1. Provide electronic calling service to replace traditional manual calling
2. Set up independent conversation rooms to avoid discussing the patient's condition in the ward
3. Use silent equipment, such as silent wheels, shock-absorbing devices, etc.

The above six comprehensive measures can effectively improve the hospital acoustic environment. For example, in a renovation project at a Class A tertiary hospital, the implementation of the above solution reduced daytime noise levels in wards from 65dB(A) to 45dB(A), and nighttime noise levels from 55dB(A) to 38dB(A), resulting in a 40% increase in patient satisfaction. We recommend that hospitals adopt appropriate noise reduction measures based on their specific circumstances to create a positive recovery environment for patients.
