I have a few thoughts on church bells and calls to prayer. First and foremost I think loudspeakers, recordings or any thing like that should be banned - for all places of worship. If you haven't got real bells, that's too bad, and if you haven't got a man with a loud enough call, that is too bad also.
Church bells are quite marvellous in my view, and ringing them is a skill - a tradition that should be preserved until it dies out. Also I don't think Church bells are rung twice a day anywhere. My personal experience in a city is that they ring a few times on a Sunday and there is bell ringing practice one evening per week. Other than that it is for special nationwide occasions, and locally for weddings and funerals. Twice a day would be overdoing it - as it is for mosques. Also there is nothing traditional about technology for calls to prayer. So I am rather biased towards church bells, because I like them.
As an aside, if you ever find yourself in Liverpool Anglican Cathedral [
well it's possible that you might] then take a trip up the tower. Near the top you will find yourself on a walkway encircling a vast drop down the middle of the tower. This walkway is above the bells and you can look down on them and see their workings and how enormous they are. Wonderful sight.
