I stay in Sir M.V. lay out 3rd block, near sonnenahalli bridge, ( near Amma ashram ) Bangalore -56. Here, the temples use loud speakers from early morning. There will be night Harikatha in one of the temples (it starts after 9.30 pm & ends the next day around 7 am) on some days of the week. In the morning,we hear some 2-3 loud speakers disturbing the sleep & peace. Hope the concerned authorities will look into this. Was this information helpful? | 
Btw, was your problem solved. I am very sure, no one might have approached you. As i see a list of such complaints since last 5 yrs continuously :D
