Piccadilly Line the noisiest Tube line

摘要

Travellers using the northern section of the Piccadilly Line suffer the noisiest journey on the Tube network, it has been revealed. A study undertaken by Antony Gregson as part of his MSc dissertation at London South Bank University showed passengers endured a noise level of 87 dB dBL_(Aeq,T) between Bounds Green and Southgate. Close behind were the Northern, Central, Bakerloo and Victoria Lines where between station noise levels reached 85 dBL_(Aeq,T). In comparison, noise levels on the overground sections of the Tube were between 68 dBL_(Aeq,T) and 75 dBL_(Aeq,T).
