The Minaret

In the past a man called a muezzin climbed to the top of the minaret to call the azaan, (the call to prayer), five times a day. This is now done using loudspeakers - these can only be used at some times in the day, and not early in the morning here in Bradford.
Q. Why is the loudspeaker system not used for all prayer times?
