As an AI language model, I do not know all the possible ways that landscape architecture addresses noise pollution, but here are a few:
1. Planting: Planting trees, shrubs, and other vegetation along roads and highways or around buildings can help absorb sound and reduce the level of noise pollution. Vegetation with dense, broad leaves, such as evergreens, can work especially effectively.
2. Fountains: Water features or fountains in public spaces or gardens can help to mask unwanted noise pollution with the sound of moving water. The sound of the water will make it more difficult to hear, or better to say, less intrusive to hear external sounds.
3. Walls and barriers: Landscape architects may use sound barriers made from materials such as concrete, wood, or earth berms in urban areas to help block the sound waves from entering the area. These walls not only absorb but deflect sound waves in other directions away from the place.
4. Creating quiet zones: In urban areas, landscape architects may create quiet zones. These zones prohibit loud music and other noise pollution, creating peaceful areas for people to relax and unwind.
5. Design of outdoor spaces: With noise pollution being factored into the design, landscape architects may use specific materials or designs that absorb sound, reducing the effects of unwanted sound on people who use or reside in the area. For example, landscape architects might strategically use bushes, earth berms, and other sound-absorbing materials to help prevent sounds from traveling into a space.
Of course, a landscape architect's approach to noise pollution may vary depending on the specific project at hand and the type of area where the project is located.
