My immediate neighbour is always drilling, sawing and hammering, and many of my neighbours have parties and barbecues. They don't bother me. I play my piano flat out at all hours. It is scarcely audible from any of the neighbours' houses, even if they stand outside. I asked them all if it bothered them and they were surprised I played the piano because they had never heard anything. However, years ago, when I lived with my parents all the neighbours used to remark about my playing (fortunately they liked it). I think it's something to do with bricks. A brick house shuts in the noise much more than a wooden one.
