No, main bearing noise is a rumble Throw out/release bearing for the clutch will only be heard when the clutch pedal is depressed. If you hear the noise without the clutch pedal being depressed, it is most likely the gearbox first motion shaft bearing that is at fault. First motion shaft bearing noise usually goes away when the clutch pedal is pressed.
Sound waves are carried throw the air. But sound waves can also travel throw liquids, such as water, and even through solids.
When the clutch is adjusted properly the throw-out bearing is COMPLETELY disengaged as soon as you take your foot off the clutch. A throw-out bearing that is lightly touching the pressure plate can often make noise, especially if the bearing is getting ready to go. Make sure the clutch is properly engaged. There should be about an inch of play at the top of the pedal throw. Also make sure all of the springs are in place, pulling the clutch forks off the bearing.

It may. It may also be a pulley or bearing going bad.
Typically.... Connecting rod bearing / crank bearing. But it could also be piston slap, or flywheel.
Your clutch throw-out bearing may need replaced.
When a TO bearing starts to go bad you will hear noise when you push on the clutch. Also shifting will be more dificult when at slower speeds.
The throw out bearing usually snaps in place on the clutch folk. There is a alignment tool you can use to align the clutch disc with the pressure plate. Also note the correct torque when mounting pressure plate to flywheel.
When the wheel bearing or hub assembly goes bad in any car, you will hear a moaning sound from that wheel which will increase/decrease with speed. Also if you jack up the car, you might feel play in that wheel.
When you push in the clutch if it rattles that is not the transmission but the clutch throw-out bearing. not necesarily the throw out bearing it could also be bad springs or fingers on clutch pressure plate could be cracked or loose fly wheel or could be one or more bad bearings in the gearbox
You replace it. As long as you have the transmission out, you might as well put the clutch and pressure plate in also.
Mine (2002) does it when the traction control comes on when I hit a bump hard, etc. Also could be wheel bearing going bad.
