London Underground (subway) measured noise levels

Not sure quite where to post this, so admin please move it if necessary.
Got this from a freedom of information request on the internet about the noise levels at Bank station (one of the London Underground stations). Seriously loud at times, highest recorded 123.1 dB. Not continuous but still ...
No wonder I got tinnitus since starting to commute into central London! I'll definitely be wearing ear plugs for all tube journeys.

"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.

Not to mention the loud speakers on the platforms. Argh.
