As someone earlier suggested, have you checked the power steering reservoir, and made sure it’s not low ?
The alternator might be struggling – either it’s broken or because the battery needs to be replaced.
Also rev specific noice might be caused by the aircon. compressor (broken or low fluid level in the aircon. system) or even a broken power steering pump or a water pump.
If the noise also changes when you turn the steering wheel it’s most likely caused by the power steering pump.
