Theme parks are usually full of noise from people on rides and music, but Alton Towers has been told to quieten things down.
The Staffordshire theme park has fitted gadgets to its loudspeakers to make them quieter after a court case.
A couple living nearby complained Alton Towers made their lives a "nightmare", and wanted it made quieter.
Now that's happening, but the park owners say it won't make a day out there any less fun.
There are other ways the park can make things even quieter, but they're on hold until an appeal against the judge's decision is heard.
The couple who complained live in a cottage in a hamlet called Farley which is only 90m from the entrance of the park.
The appeal will be heard on 11 April.
