Noise levels within London Underground's network is becoming a nuisance for tube drivers, passengers and residents along certain sections of the Northern, Victoria and Central lines within the network.

This footage shows a tube departing South Wimbledon on the Northern line and heading to the terminal station Morden where the noise is still highly audible long after the train has left the platform.
The second part was filmed inside a tube carriage along the same section of track where the excessive noise levels continue for a minute.

The filmer has noticed in the past six months that this section of track between South Wimbledon heading towards Morden becoming so unbearably loud that she has observed other passengers covering their ears.

Academic, Dr Joe Sollini, of UCL's Ear Institute, interviewed by the BBC explains that damage to hearing is accumulates over many years and excessive noise over long journeys could contribute to hearing loss.

Testing of noise levels carried out by Transport for London says the loudest sound recorded between these stations was 113 decibels, a similar level to a live rock concert or standing next to a helicopter while it takes off.
An acceptable working noise level is under 85 decibels.

Some commentators suggest the increase in noise is down to TFL's new concrete sleepers that are less able to absorb sound causing misery for residents living close to stations offering Night Tube services.
