Architectural ordonnance can be used to support the building's noise reduction goals in the following ways:
1. Designing partitions: Walls and partitions can be designed using materials that have high sound transmission class (STC) values. STC is a rating of how well a material can block sound. Increasing the STC value of partitions can help reduce noise transmission between rooms.
2. Creating sound-absorbing spaces: Certain spaces within the building can be designed to absorb sound, such as using carpeted floors, acoustical ceiling tiles, and wall panels. This can help reduce sound reflections and reverberations and improve speech intelligibility.
3. Controlling sound pathways: Designing the building to control the paths that sound can travel can reduce the amount of sound that reaches sensitive spaces. For example, locating noisy mechanical rooms away from quiet spaces, installing sound baffles or barriers, and using quiet HVAC systems can help reduce noise intrusion.
4. Reducing impact noise: Impact noise occurs when an object strikes a surface, creating vibrations that transmit noise. Measures such as installing floating floors, using resilient materials between floors, and isolating mechanical equipment can reduce impact noise.
5. Minimizing exterior noise: Building orientation, landscaping, and the use of sound-absorbing materials in exterior walls and windows can help reduce noise from outdoor sources.
By incorporating these strategies into the design of a building, architects can help reduce noise levels and create a more comfortable, productive, and healthy environment for building occupants.
