i want to insulate my bedroom from the noise coming from my upstairs neighbours . the construstctor advised me of using rock wool density 100 and then gypsum board underneath it (false ceiling). my questins is : is it useful to stop the heels sound and banging and moving furniture sound coming from above ?
i will try it in my bedroom only but would the noise coming from upstairs spread to my room through the other rooms not sound proofed in my home e .g . setting room or corridor between rooms and if , yes, would it be lower after sound proof ?
