The decades-long search for the Bristol Hum
The Bristol Hum – a mysterious low-level noise that only some in the city can hear – is back in the headlines on the BBC. But did it ever go away? As far back as April 1980, Bristol’s environmental health officers were using noise monitoring equipment to try to track down the source. More than 100 complaints were logged, according to the archive from April 1980 and the BBC Points West records.
Now in the latest flury of interest, the BBC has been able to uncover further explanations, including one from MACH Acoustics’ Director Ze Nunes – who tells us hearing can be subjective and not a black and white matter.
