HELP… noise from the stormpipe

Hi there,

I think the problem I have is kinda of impossible to be fixed, but I am hoping for a miracle.

I live in a residential apartment and am on the ground floor. When the building’s storm pipe gets to the lower ground floor, it has a 90 degree bend near the ceiling, then goes along the ceiling and gets to the basement after another 90 degree bend. My bedroom is being very close to the bend (pretty much just above it), whenever it rains, the water coming straight from the top roof hits the bend and makes loud noise. I’ve had the bend wrapped up by soundproofing material but the change is little.

Is there anything else could be done to minimise the noise or I have to put up with it? Please help me….

Thank you very much!
