Koran on use of loud speakers in mosques

[chound]

I live near a mosque, I've had no problem so far regarding the use of loud speakers to pray. But since the last month they've cranked up the volume so high it's unbearable. So I want to know if the Koran asks 4 people to go on the minarets and shout and pray or 4 loudspeakers?

لْقُرآن

The human voice is used to announce the times of prayer to the community. The adhan ( ذَان ) is the call to prayer itself, and the person who calls it is called the muadhan (muezzin).

Modern mosques use loud speakers - so this is a new development. I doubt the Qur'an addressed the volume since individuals would have limited volume. Likely the procedure(s) for adhan are in the Hadith, perhaps by al-Bukhari.

Perhaps one can ask the Imam.

I want to know whether the Qur'an specially asks for humans to sing the prayer or vaguely mentions a voice?
