engine noise while accelerating

Hello,

There are multitude of reasons for an engine can make noise.
Today's car engines are designed with more complexity and moving parts than ever before. When you hear abnormal noises there is something wrong.
It could be a worn wheel bearing that makes humming noise as you got down the road, and it just appears to be coming under the hood.
