Rats don't' tend to run on wheels as much as hamsters and mice but can be just as boisterous. My rats are running around, wrestling and chewing each night but I have grown used to it except when they have a fight and start banging around..or an 'elbow' PVC pipe section ends up close to the side of the cage and bangs against the side as they run through or wrestle inside of it.
The nursing babies though, are the noisiest...yet for some reason I find it soothing...
