Soundproof and sound-absorbing material testing

Noise Detection Methods

1. Standard Outdoor

Measure at least 3.5 meters from all reflective objects except the ground, and at least 1.2 meters from ground level. If necessary, position it in high-rise buildings to expand the monitoring range. When using monitoring vehicles, the speaker is mounted at a height of 1.2 meters on the vehicle's roof.

2. Outdoor areas of buildings sensitive to noise

Outside of buildings sensitive to noise, at least 1 meter from walls or windows, and 1.2 meters above the ground.

3. Noise-sensitive building interiors

At least 1 meter from walls and other reflective surfaces, about 1.5 meters from windows, and 1.2 to 1.5 meters above the ground.
