The Black Hole......

To completely change the subject, I am working on the acoustic characteristics of the very common US roll up vinyl window blinds. Are these common elsewhere?
Not common here as we usually use fabric blinds but are available for bathrooms.


The interesting characteristic is that the primary mode of sound absorption is diaphragmatic unlike thin drapes.
not suprising. Especially if they are fitted inside the window frame.

Anyone using them to control acoustics?
no, as I don't have a system in the bathroom. Have heavy curtains in the living room but as the sofa to volume ratio is high I don't need to absorb bass (oh and the piano stuffs the acoustics anyway).
 
Many years ago it was noticed that Madeira was very tasty in a cold, damp, English drawing room, but nausea-inducing when consumed at the semi-tropical source. The Brits concluded that Madeira benefitted from shipping, something to do with salt air and the rocking of the ship. A wealthy American architect purchased a cask of Madeira every year and paid to have it shipped twice around the world on slow freighters, so as to have the best-aged Malmsy available. Had there been audio equipment around back then I bet he would have had killer cables!
 
I have been at diplomatic lunches where bottles of Petrus were opened with casual ease. So no, it gets drunk.

Between 1970 and 1972, Cru Classé prices increased by a staggering 400%, before crashing back to 1970 levels in 1974. Many of the top négociants were simply wiped out, whilst, in 1975, one particularly unlucky Londoner sold 2,000 cases of Mouton 1970 for £74 per case. Five years later it was £990 per case.

It was fun to be into wine in 1975.
