Noise monitoring devices are arranged at different positions in the residential areas, and the noise monitoring devices with different densities can be flexibly erected according to the severity of noise pollution. Aiming at the noise pollution serious disaster area, a larger number of noise monitoring devices can be arranged; for the region with occasional noise pollution, a certain number of noise monitoring devices can be arranged.
A noise monitoring device includes a plurality of noise receivers, see fig. 2, for example, eight noise receivers, which are uniformly spaced in eight directions on a horizontal plane of the noise monitoring device, namely, eight directions, namely, true south, true north, true west, true east, west north, east, and south east.
In this embodiment, the direction indicated by the noise receiver with the highest sound intensity may be selected as the transmission direction of the noise. Of course, other existing ways of detecting the noise transmission direction may be fully employed. Optionally, the transmission direction may also be verified by using the time of reception of the noise, and the receiver with the highest sound intensity usually receives the noise signal at the earliest.
S102, aiming at two groups of noise signals detected in the same time period, the sound similarity between the two groups of noise signals is calculated.
The same noise source may be monitored by a plurality of noise monitoring devices nearby at the same time, and in this embodiment, for the noise signals detected by each noise monitoring device within the set range, if two or more sets of noise signals exist in the same time period, the sound similarity between every two sets of noise signals is calculated. The method for calculating the sound similarity may adopt any existing method, which is not limited in this embodiment.

And S104, determining the target space position corresponding to the noise source by combining the space positions of the two noise monitoring devices which detect the two groups of noise signals and the transmission directions of the two groups of noise signals by utilizing a triangulation positioning principle.
Referring to fig. 3, the spatial coordinate positions of the noise monitoring device B and the noise monitoring device C are known and can be marked on the map in advance, so that the distance a between the two is clear; for the same noise source, the noise monitoring device B can detect the transmission direction relative to itself
