TfL Ref: 0222-1920

Thank you for your request received by Transport for London (TfL) on 20 April 2019 asking for the highest noise level in decibels on the Jubilee line as it travels between Bermondsey and London Bridge stations in either direction and if this falls within safe guidelines.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy.  I can confirm that we hold the information you require. The data is as follows:

Bermondsey to London Bridge WB – 01 April data – 114dB Peak (C)

London Bridge to Bermondsey EB – 11 March data – 110dB Peak (C)

TfL are obliged to comply with The Control of Noise at Work Regulations 2005. These regulations stipulate noise thresholds which are enforceable with regards to employees, but can be taken as a guide to noise exposure to members of the public within our workplace environment.

The regulations set the following thresholds:

(1) The lower exposure action values are—  a peak sound pressure of 135 dB (C-weighted).

(2) The upper exposure action values are— a peak sound pressure of 137 dB (C-weighted).

If this is not the information you are looking for, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely
