As Network Rail have stopped the sounding of train horns as a matter of routine between 11pm and 7am, will London Underground do the same at those stations on the Northern Line where it can be heard in houses and flats in the surrounding area?

Answer for Underground Noise

The whistles on a London Underground (LU) train are quite different from the horns of an overground train - as are the regulations around their usage. LU trains may need to sound whistles when moving about in the depot as an alert to staff in the vicinity and when going in and out of tunnels when overground to alert anyone who may be on the track or in the tunnel. Existing requirements are already in place at LU that limit the sounding of train whistles between 2300 and 0700 hours. Measures have been taken at key sites such as the overbridge south of West Finchley station to minimise unnecessary noise at other times.
