The St.Trudo church has the strongest bell among the churches belonging to the St.Joris Parochie in Eindhoven. Four microphones are planned to be placed in the area on the east of St.Trudo – in the church tower, and preferably in The Passaat Archipel, Lindenlaan and Keerweerstraat. The distance between the farthest microphone and the church tower would be around 515 meters.
