Sir – Last Saturday night I was kept awake until way past dawn by non-stop bass drumbeats. They would occasionally fade, only to start up again with the same monotonous rhythm.

About 5.30am I got up, dressed and went out with my imaginary shotgun to try and find the source.

I walked pretty far, back and forth, but it kept disappearing, then reappearing. Very strange. Returned to another hour or two of drumming (double-glazed windows closed, solid brick house on the Banbury Road), even tired and with earplugs, the low beat kept longed-for sleep at bay.

Was I in Guantanamo Bay? Was Britain under attack from a new kind of long-distance low-resonance warfare?

I discovered on Sunday, from a passing conversation by Osney Lock, that those on Osney Island were also affected, that being about a mile from where I was not sleeping.

The noise must, therefore, have affected a good swathe of the city's population. It turns out to have been an all-night rave near Eynsham, and it hit Oxford, since the wind was blowing our way.

Am I the only person to think there must be a way to make the organisers of such events responsible for this kind of disturbance?
