Asbestos tests

The buildings I work in have asbestos and we had an inspection last week. 

I was fascinated to hear the testing undertaken with a tap to identify the denser asbestos panels from the lighter masonite ones. The former have a higher pitch than the latter.

The bloke testing them described the asbestos panels as "sharp" while the masonite panels were "flat" and this got me thinking about musical terms.

It's not really accurate description unless panels have a consistent key but did convey the audible differences.
