Neighbours have a full live band in the back garden, parents included. Sadly they are not very good and incredibly loud. The sessions are completly random, sometimes in the evening. We have asked them if they can turn the amps down as its deafening and very annoying but they are the kind of people who are simply unreasonable and claim they can do whatever they want in their garden. There is never any notice that they intend to have a party or a practice session.
Does anyone know what the guidance for such things are? Are we being unreasonable having to wear earplugs in our own home?
