Is it true that the aluminum foil bonded in home insulation materials also reduces sound transmission?
I find hard to believe that something as thin as the foil, will significantly reduce noise.

It is not for sound insulation
It is used in HEAT insulation and is quite common building practise.

Not really. The ability to attenuate sound energy is found in the fact of dampening devices. Sound energy must be absorbed. Since itis propagated through the air the best way to do it is to capture it. That is done in many ways but themost common and economical way is to PLUG all holes to seal out the entrance of sound energy carring air (a single sheet of alumiinum foil will not do that) and then to INCREASE the mass of any material that will retransmit or amplify the sound energy, like a metal car door panel.
By placing a self adheasive high mass material (like lead) onto a sheetmetal panel you increase the mass of the panel and its ability to attenuate the noise. The sound energy is dissapated into the mass and is converted into heat energy and dissapated into the surrounding metal panel and eventually into the air where the heat is carried away.
Lead is a good, but NOT practical material for sound attenuation. There are products available at auto stereo stores that will make for a good sound dadned using the principals I outlined here.

If you grind aluminum into fine powder it get explosive & makes rocket fuel.
I don't think it would make very good sound insulation, but ya never know.

it i a Little thicker in home insulation but yes it will reflect sound waves

that ain't true. You cannot use aluminum for insulation in that form.
