The least resonant/reverberated material is ?
« on: 01/02/2008 14:50:04 »
Dear Sonic Scientists,

D'ya like my Beethoven clock ?



Available at all good Beethoven Clock and Beethoven related stores in a country near you !!



As ewe may know....Beety or Ludy (as he liked to be called) went 'well-death' and stuck a stick in his gob and used this to hear things by placing the other end of the stick on his piano, drum kit, synth amp !

Say, you wanted to deny Beety this pleasure ?  apart from demonstrating poor gamesmanship...what solid material is the best at NOT conveying sound through itself ! ?


I don't know....I really don't !!..

Lead is good and widely used but I don't know which material is best (also it depends on the range of frequencies you want to damp); I would say something like gelatine maybe.

For a material not to convey sound, it must be capable of converting it to something else (commonly to heat).

The best way of doing is at the boundary between two bits of solid that would rub against each other - so the best things to use are not single lumps of solid material, but lots of little bits of material (e.g. grains of sand).  Cardboard is ok, because it has lots of fibres that can rub against each other, but cardboard egg boxes half filled with sand is probably better (half filled so that the sand is not packed tight, and can have room to move).

Ofcourse, arguably the best thing for stopping sound is a vacuum.  The problem is that most containers that stop the outside air from flooding into a vacuum can be very good sound conductors, so allowing the sound to pass around the vacuum.

Foam can provide acoustic insulation, (as used in recording studios)...

But again, foam, by its nature, is composite (at least insofar as it contains bubbles of air, and so lots of internal surfaces where it can dissipate sound).

I would have to agree with a vacuum- I didn't think any sound could pass through it- as it contains no particles for the sound energy to pass through...

So, it seems the best way to deny Beety his sound is to stick a hoover in his gob. :D




Thank you all for your wonderful answers

Opus,George,RD and Alberto...

...oh and Eth (for his hand of friendship...awwww [:I])

You can also use some very new tiles that can be bought.. kind of like a dry wall stuff but different.. I will find out what it is! There is also better yet some fairly new spray in insulation they spray into your walls and ceiling. It is a sound proofer also.. one of its selling points for people who are musically inclined to blast there music! LOL!
