Its owner, Tussauds – recently acquired by Merlin Entertainments – faces new action from Stephen and Suzanne Roper, who claim that noise levels are still too high despite the restrictions the park has introduced.

The park’s lawyer told the High Court that the 40-decibel level was ‘rational’ and residents could not expect ‘tranquillity.’

He said that World Health Organisation guidelines said noise levels of 50-55 decibels were acceptable "below which the effect of noise should be negligible."

If the Ropers lose this new case, it is possible Tussauds may seek to overturn the original noise abatement order.
