Rain at night in Blackburn
We count a noise night whenever an hour between 11pm and 7am brings 0.5 mm of rain or more, the Met Office's moderate band. Blackburn had 87 a year, more than the 65 of the average town, and 7 nights with a heavy hour over 4 mm.
In the lab, heavy rain on 25 mm polycarbonate measures 64.6 dB against 52.0 dB for double glazed roof glass. Nobody has published the same test for aluminium panel roofs, so we will not put a number on ours. How loud rain is on each kind of roof sets out what is measured.
- Light (under 0.5 mm an hour)681 h
- Moderate (0.5 to 4 mm)668 h
- Heavy (over 4 mm)39 h
