onBlackheath meeting: Bad Tempered Bongo Drums

Below are a tonne of interesting tweets from yesterday’s onBlackheath meeting (which I couldn’t attend). Mostly from BitOClass and Darryl1974 who write the SE13zure and 853blog blogs respectively.

I wish I’d managed to get there, looks like it was an interesting night. Regardless of your opinion on whether the festival should go ahead, I think it’s worth pointing out a few aspects of sound perception:

Sound pressure levels decay over an inverse square law with distance. So if you are very near to the source of a sound, and move a few metres away, the sound gets dramatically quieter. However, if you are a hundred metres away, and move another few metres back, the level barely changes. Another point to make is that decibel readings are fairly pointless as way of describing irritation from unwanted sound. For example, a continuous sine tone or burglar alarm can be very irritating even if it is at a low level, whilst a spread spectrum of pink noise at an equivalent total energy level might be barely noticeable. Music is in the ear of the beholder, so sits somewhere between the two. Finally, anyone who thinks that erecting a few soft temporary walls in the free field will make any difference frequencies below about 1kHz should really think again.

Tweets are below in chronological order. Don’t miss the bit about bongo drums.

Blackheath Fireworks 2010 Roundup

So yet again, Bugle-Dad-birthday (and a wedding to attend) meant that Mr & Mrs Bugle could not, and possibly will never manage to attend the biggest and best fireworks display held in their back garden (almost). So instead, to compensate I have re-lived the event by tragically staring into my laptop screen, whilst waving a sparkler. More below:

Lovely high definition video of the fireworks, from a Nokia phone (youtube user macintoshmorrisson)

An historical perspective on bonfire night in Blackheath from Andreas Moser, with links to more youtube videos.

“As far as I am aware, this is the only country that annually celebrates the failure of an assassination attempt on its head of state.”

When you put it like that, it does sound a bit odd…

Another HD video of the fireworks (no point in watching them at a lower rate!)

Great photo by Liam Hayter. Makes me wish I’d been there.

Blackheath fireworks were great. Lewisham Council showed Greenwich how to do it: big, not too long, no awful music. http://yfrog.com/eqt1hfj

All of Blackheath is engulfed in a thick low-lying smoke. Quite amazing, feels like a film set.

Blackheath fireworks. The best thing Lewisham Council does. http://twitpic.com/34joan

Apart from, you know, the schools, hospitals, GPs, libraries, etc etc :)
