Please mention the model/year of the Mac.

Are you able to distinguish if it is from internal speakers or fan noise.

Please see if safe mode helps to troubleshoot.

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
