Rattling Noise (clutch?)

I have a 2001 Honda Civic with 66k miles on it.

I've recently noticed a rattling sound that I can hear when the car is idling. Upon depressing the clutch, the noise goes away.

I've also noticed that the car makes a bit of a similar noise as I'm accelerating and decelerating.

My budget is somewhat tight so I don't want to make any unnecessary repairs, but at the same time if something needs to be done, I want to take care of it as soon as I can.

Check the heat shields attached to the exhaust pipes (and both sides of the exhaust manifold). They rust loose with distressing regularity,

Get under the car (exhaust cold) and tap away with a finger until you find the shields that rattle. If you find any, you can use worm-type hose clamps to snug them up.

If there are surely no heat shields loose, THEN start blaming other parts of the car.

Thanks, Tegger.

If it is a loose shield, why would the noise stop when the clutch is pressed in?

I'm no auto genius, so I'd like to know as much as I can before I head into a repair shop.

'Cause the engine's vibration frequency changes.

There are several things that are different when the clutch is depressed. If everything is working correctly, when you press down the clutch the shaft into the transmission and the clutch disk should stop turning and the throw-out bearing should be turning (with the clutch out the throw-out bearing should stop and the tranny shaft and clutch should turn). That change might cause something innocent that is rattling to stop rattling. But that could be a sign of something not quite right with your transmission or clutch if it is causing a vibration that is showing up elsewhere. Or the sound could be coming directly from one of those components (throw-out bearing clutch or tranny shaft). Or it could be that just the change in mass of rotating parts changes the frequency enough to make the rattle disappear. No one is going to be able to tell you what the noise is without more info. Are you having any problems with the shifting? When you press the clutch just lightly what happens to the sound? More than likely it is going to take someone observing directly at the parts with the car running to find where it is coming from.

This could be the transmission gears vibrating against each other because of excessive play and/or thin oil. This usually occurs after the oil heats up and thins out.

This could be another problem, such as the common vibrating heat shield.
