you live in a house and you essentially DJ all day long at volume and you want to ask if this is ok?
I doubt anyone is that daft they need to ask tbh.
as for the Barbies and the conversation – it all depends can my kids still play in the garden or is the smoke and conversation enough that I cannot let them? Imagine I let my kids blast into your garden with water pistols to stop you enjoying your activity.
Basically you do as you please and dont really care if it impacts on anyone else. You dont actively try to annoy them you certainly dont try not to.
Like the roads it is shared space and you can be fair or not fair
