A mile along the towpath I encounter the noise that has been keeping me awake at night. One of the battleship grey industrial sheds that stand between my house and the canal has sprouted a trio of stainless steel silos which emit a low hum, as of an out-sized extractor fan. It's not a loud noise, but I'm sensitive to low frequency vibration and the hum has been disturbing me. Maybe it will bother me less now I know what it is. But if it does this to me, with my not-so-acute human hearing, what does it do the local wildlife?
