Not sure what your filter looks like, but mine have been too noisy also, mine are internal filters, so I put some white media filter stuff between the back of the filter and the glass (had to ignore the sunction cup)- and this absorbs noise and vibration, making my Larry Guerry betta fish- much happier.
If yous is HOB, perhaps you can put something between front and glass to absorb noise? Not sure.... good luck!
