Best conductors of heat are also the best conductors of sound. Agreed?Sound and heat, both are forms of wave energies. An energy is distributed through a driving force,I.e..; disturbance in molecules.
Velocity of sound is the fastest in air, but it's intensity is the lowest in air.
Velocity of sound is lowest in solids, namely metals, but it's intensity is pretty high.
Heat too, has solids, that too metals, as it's best conductor.
We are only talking about conduction. Don't bring in radiation or convection in between.
So can we agree that the best conductors of heat are also the best conductors of sound?
A practical approach is, your hearing efficiency grows rapidly if you use headphones than listen to something in speaker.
Solids conduct sound better by minimizing the losses.
Then can viseversa be true too? Bad conductors of heat muffles the sound.
I bet it is true. Wood, bones, plastic, sponge, gums..etc..; are poor conductors of heat. And guess what? They are also the materials used in sound-proof walls,to absorb the sound.
Are you in unison with my observation?
