However there is a byelaw which says that
no-one is allowed to use equipment for the reproduction of sound "to the
annoyance of any person" - which is slightly different.

I wonder if this bylaw would outlaw the use of mobile phones! I certainly
get annoyed by use of phones on trains and buses. Does anyone know of any
organisation campaigning for reduction in use of mobiles.
