Rain makes an obnoxious tapping sound??

I had new eaves installed three years ago. Every time there is heavy rain I can hear a thudding noise coming from over the roof into the second story bedroom. It sounds like water dropping into a bucket. I wonder if there is a design or installation flaw with my new gutters/eaves? One contractor suggested I put a thin sponge into the elbow from the second story that feeds into the main floor. Before the eaves were replaced there was no elbow at this point and the water had a clear drop. I wonder if this could be creating the annoying thudding noise coming from the roof. Or is possibly something else? We never had this issue before the gutters were replaced. Any help would be appreciated. My sincere thanks in advance.

There are little strainer inserts' you can get to put in the holes that go from the trough into a downspout, typically too catch debris. I am thinking as these also break up the flow a bit to slow it and maybe stop any extra noise further down system. Just an idea otherwise it is likely very normal for the sizing of the new system as installed. Sponge idea sounds interesting too but then obstruction in line will collect debris over time and clog it? Eavestrough supply companies are best places to get odds and ends as opposed to a hardware that only carries limited products.

Thanks so much John. Appreciate your help. Another person suggested putting a pot scrubbing pad or plastic scrubbing pad into the elbow to help with the noise issue. I'm no engineer but I find it hard to believe that the bottom of this elbow could cause a noise at the top of the roof. We have a two story split and the noise is right at the peak of the roof over the bedroom. Someone else told me it could be the flashing or the soffit or roof leak. But we had a new roof installed 7 years ago. I'll try anything to minimize this noise.

Not my area of expertise, but I hear the same thing with my neighbours house. Sounds like somebody tapping on the downspout.

I don't think it is a design flaw per se, but you probably got larger spouts installed and the with no obstructions the water can basically fall and hit the elbow.
