Was the noise before the new belt or after?
Is the new belt properly tensioned? Proper size belt.... (length, width, number of ribs)?
Trying spraying belt dressing on belt with engine running... careful!

Do you hear the noise when the engine is running without the belt?
Try another belt.

Any excess lateral play in pulley bearings, water pump shaft, etc.?
