rushing sound in pipes by sink

Hi, the sink in our master bath is making a rushing, white noise sound. It sounds just like after you flush the toilet and the tank fills up, but this sound is going on all day. It seems like it is back in the pipes in the wall or in the cabinet. The sink is working fine and there is no sign of leaking. The sink is about 8-10 feet from both the bath and the toilet, on totally separate walls and there is nothing above it. Any ideas?? Thanks!

A little more info would help.

Are you in a single home, apartment, condo, etc?

Is the home on a slab?

Are you on a well or city water?

Water noise

Try shutting the water off and listen to see if the sound goes away.
You may have a slight leak under the slab.
Check your water bills.
