None, as long as you keep the tank full lol. It makes a trickling noise as it pushes water over the surface if you let the levels drop below the spout. Otherwise, no motor sounds or anything. At least for the Tom Mini Internal filters that I use. :)
Another alternative for a filter is the Azoo mini filter. It's external, but is very quiet. I haven't tried it with long finned bettas yet, but I have it on Brutus' tank on the lowest setting. I think the internal filter works better for long finned bettas, but either would work for a shorter finned betta.
