Have just spent the morning hanging a twenty-thousand-dollar sound meter off the edge of a top floor balcony at the Docklands Hilton. Not exactly “fun” but definitely interesting–I was helping my mate Ben who is in town record the noise of a Eurocopter ec145 (as it landed on top of the Docklands café society). In the end, it was surprisingly quiet, not that I’d want a heliport in my neighbourhood…
