issue is finger pointing at Muslims. Guru-dwara and Temples do this noise pollution as well. Infact Gurubaani runs for hours together and so does keertan in temples. A Jaagran --literally means keeping awake-- during durga pooja is very very loud. I challenge anyone to sleep during that time if you are near a place where they have set up the idol and they are doing the Jaagran. Its a 9 days of high decibel madness.
Mosques ALL OVER INDIA use loudspeakers.
I am not aware of Temples ALL over India using loudspeakers. (Not the cement concrete make shift temples)
