A mysterious background hum has led Kingston Council to issue noise diaries to Surbiton residents.

The noise has been an irritation for weeks, but the source of the noise itself remains unknown.

One Surbiton forum user said: “I can only describe it [as] white noise and quite low frequency.”

Another added: “The noise is very low frequency and is a humming, whirling motor sound. You can hear the sound in every room of our flat.”

Glenbuck Road and Avenue Elmers residents reported hearing the hum throughout the day and night.

Forum users speculated it may be emanating from within Surbiton station, or behind McDonald’s.
