depends on what the surface looks like but wood would most likely absorb more sound and therefore muffle it because it is more porous then smooth plastic or metal

It is about how closely the particles are packed. As they are all solids they will allow more sound to pass through them compared to liquids and gases. The metal will have closely packed particles but also free electrons which will move around the particles to spread the sound. Plastic as in plastic bottles (hard plastics) are more brittle which would again suggest the particles are packed closely together but without the free electrons. Therefore i think the wood would be best at muffling the sound. It does depend as someone already mentioned what type of wood it was.

Non of these three materials are very good at favorable acoustics. However, the wood would be the best due to porosity. In this category, pine would work better than a hard wood, again because of the porosity. Plastic and metal cannot absorb water, gasses, light, etcetera. Therefore, cannot absorb sound either. Wood can. If only marginally better.

Density is the key!!!
It does not depend on the material as much as the density of the material. For example a hard dense plastic will transmit sound much better than a soft balsa wood, but a hard wood (oak) will conduct sound much better that soft plastic foam.

This is a basic physics question. It has to do with the ability of the various substances to transfer heat/cold. Metal is a good conductor of heat; wood is not. (Early insulators were made of wood, both for electricity and heat insulation. In fact, when you buy insulation, the "R" value of insulation is based upon the equivalency of wood. An "R" value of 1 means it has the same insulating value as 1" of wood; R15 means it has the same insulating value as 15" of wood.) Because metal easily transfers heat, it feels cold when the weather is cold, and it feels hot when the weather is hot. (Or the room, etc. This is also why a cat loves to be on concrete on a sunny day in winter; the concrete, like metal, transfers heat. And, of course, it is also why concrete cracks...)

The denser a material the better blocking . Lead is best to block out sound. Foam is OK for absorption if you are in a recording room. It will not block sound traveling to the next room.

Of the three, wood is best, then plastic, then metal. Neoprene foam rubber is better than all, though.

Wood absorbs more energy than plastic or metal. I believe it is due to molecular structure.

Rough cut balsa was once used inside hi-grade speaker systems cabinets. Metal is used for bull horns. Plastic is used for boom boxes.
