Dear Mr or Ms Gregory

 

TfL Ref: FOI-0041-1213

 

Thank you for your email received by Transport for London (TfL) on 10
April 2012 asking for information about noise levels on Central line
platforms at Bank Station.

 

Your request has been considered in accordance with the requirements of
the Environmental Information Regulations and TfL’s information access
policy.  I can confirm TfL does hold the information you require. You
asked for:

 

Details of the recorded noise levels on the Central line platforms at Bank
underground station.

 

London Underground carries out noise monitoring at Bank station at least
every 6 months to ensure compliance with the Control of Noise at Work
Regulations 2005. The below table shows the last three sets of results.
Two types of measurement are in the table, ‘dBA Leq’ and ‘LCpk’.

 

dBA Leq is the Equivalent Continuous Level. It is useful to think of it as
a type of average, where noisy events have a significant influence. LCpk
is the C frequency weighted peak sound. The Noise Regulations contain
action values and limits that London Underground adhere too. Staff work in
the centre of the platform for a maximum of 1 hour per day to ensure noise
exposure is as low as reasonably practicable.

 

The noise at Bank is caused by trains, so staff and customers are only
exposed to loud noise when a train approaches or leaves the platform.
Customer exposure is typically less than 5 minutes whilst they wait for
their train, therefore the level of noise they are exposed to is
significantly reduced.
