MP3s are, by definition, lossy, meaning the sound was changed from the original in order to make it fit into a small amount of space. The changes are made in ways that are meant to fool the ear, but if there's not enough space, sacrifices have to be made. There are also just some sacrifices that are made as part of the MP3 conversion process, changes which occur regardless of the available space. Sometimes the various changes made to the audio can be heard as audible artifacts/noise. There's really no practical way to "clean up" this audio and remove the noise; if there were, the MP3 encoder would've done so. Anyone who says they have a "noise reducer for MP3s" is selling snake oil.
