Aerogel

Post by sel53 » 11 Dec 2019 03:29

Hello All,

This is my first post, so sorry if it is weird.

What about aerogel as a material for a turntable mat?

Compared to entering the atmosphere, groove vibrations are nothing.

Experiment freely. If you try aerogel, please let us know the results.
I have tried a number of materials, but never aerogel.

Cheers,
Alec

what is required is a material that has the same mechanical impedance as the record, but very different mechanical impedance compared to the platter material. It must have excellent damping qualities, too. This may mean changing the platter mat depending on density, stiffness and thickness of the record!

Aerogel might be a good isolation material, but the factory mat may still be required to silence and dampen the platter.
