Some guy with a motorbike has recently moved into the area and its incredibly noisy. I had a police officer friend recently stay with me and when he heard it go past, he commented 'that doesn't sound legal'...and he's a motorcyclist too. I was just in a video call with work colleagues and had the office window ajar for some air. This guy roars past and I could not hear what I was saying, some of my colleagues asked what the noise was. To say his exhaust is loud is a bit of an understatement. One time he went by, my hand on the window sill felt the vibration. Clearly, he must have an 'official' exhaust pipe for the MOT, and then puts on his 'listen to my motorbike' one to deafen the neighbourhood. How should one go about reporting this as it seems to be a violation of noise pollution levels?. By contrast, other motorbikes in the neighbourhood sound like purring cats compared to this thing.
