Closest noise sources
Description
This method returns the distance (in meters) to the closest sources of noise of the following types: road traffic noise, rail traffic noise, aircraft noise, emergency vehicles (A&Es, fire stations, and ambulance stations), ringing church bells, and bars/pubs/clubs.
For road traffic noise, rail traffic noise, and aircraft noise, if the postcode/coordinate is located within the noise boundaries, then the method will return distance = 0, and noiseClass will contain the noise level in decibels. Otherwise, if the postcode/coordinate is located outside the noise boundaries, the method will return the distance to the closest point of the area affected by noise.
For other sources of noise, the method will return the distances to the objects if they exist within the following radius:
- A&Es, hospitals, fire stations, church bells: within 483 meters, or 0.3 miles;
- Bars/pubs/clubs: within 161 meters, or 0.1 miles.
