Arizona is full of "flocked" ceilings (asbestos mixed with plaster)
with excellent thermal and acoustic insulating properties. It is
easily 'neutered" by spray-painting it, but you lose some of the
acoustic noise reduction in the process.

Any idea why spray-painting reduces acoustic insulation? Interesting,
intuitively it would seem the opposite (what was that earlier comment I made
about common sense? :).

Seems to me it would tend to stiffen and add mass, particularly if it's a
kind of paint that tends to make a crunchy, hard coating.

As such, it should reduce high frequency attenuation the most.

Keerect! The paint makes the once-soft surface to smooth and somewhat
hard.

Oh, bullshit and bullshit. Unless you're so young that to you, "10 years
or so" is a "long time". As recently as 30 or 40 years ago, whole theater
curtains were made of asbestos, and they were proud of it - if there's a
fire in a crowded theater, you don't want the curtain contributing!

The asbestos hysteria has the same roots as all the other boogeymen,
like global warming, the ozone hole, smoking, terrorism, drugs; anything
they can scare children with.

But it has nothing whatsoever to do with common sense.

Here is a quote from a paper which is written to _support_ the continuing
uses of chrysotile asbestos:

"All types of asbestos, if inhaled at sufficient doese, can cause the three
main serious health disorders: asbestosis, lung cancer, and mesothelioma."

But it IS/WAS hysteria. INSTALLED asbestos poses virtually NO threat.
However it is potentially dangerous to mine workers and installers.

And removers.
