Now I’m commuting I’m fed up of how noisy the tube is compared to the newer trains, was BREL just crap?
I’ve taken to using an audio spectrograph app on my phone to watch the white noise, and the band of resonances.
Quite interesting in probably far too geeky away, I’ve not been called up for suspicious activity whilst innocuous I’m not sure how I’d be able to explain it.
I’ve also been thinking about tracking the sound of the bath filling to gauge how much is in it, just to track not to use. I guess air pressure, and water temperature play key parts.
