Hi, if engine noise, you can up the rpms in park. Turn on some accessories, see if you can hear the noise under the hood. Sometimes I use a long shank screwdriver to hear better, place the tip against the alternator body or whatever, the other end of the shank, I place against the side of my head. My hearing is no good, listening that way helps, me. You just have to be careful not to get anything caught in a belt or pulley, anything.
If you only hear it going down the road, maybe a u-joint-- wheel bearing, something of that nature?
