That is because you can't walk into a hi-fi shop and say "I'll have 50

Yes, I suspect you are correct. However the curious thing is that shops
sell things like 'Stones' and wiggly pipes, etc, to improve the sound on a
quasi-mystical basis, but the same shops do not seem to sell more basic
acoustics materials.

For those living in the UK, the Association of Architects (or whatever the
revered body is called) have a list of those specialised in acoustics.
