Construction Site Noise Assessment
Conduct noise monitoring at a commercial complex construction site using the MT-91 sound level meter to ensure compliance with urban area environmental noise standards.

Project Background
The commercial complex is located in the city center, surrounded by residential areas and schools. Construction noise may trigger complaints, requiring strict monitoring of noise levels.
Facing Challenges
- Multiple construction phases with frequent changes in noise sources
- High density of sensitive points in the surrounding area
- Balance construction progress with noise control.
- Strict restrictions on night construction
Solutions
Set up monitoring points at the construction site boundary. Use MT-91 to conduct regular inspections and record noise data. Issue timely alerts when noise approaches limits and adjust high-noise operation schedules accordingly.
