the worst are

* bells from catholic churches (when they play early Sunday morning they just invite you to blaspheme)

* muezzin shouting from the mosque (aggravated from the fact that they talk Arabic, were in many countries, e.g. Turkey, nobody talks arabic, so nobody understand!)

and the worst of the worst is that in both cases sound comes from tapes (no live at all, and very bad taped).

Any national new legislation must face this issue: as to say it will be very hard deal with, without touching religions' susceptibility.
