India has more places of worship than schools and colleges combined. Each one is acoustically unique: stone mandapams that ring for seconds, domes that swallow speech, and courtyards where thousands gather on festival days. Most still rely on a single amplifier and a pair of horn speakers that are too loud near the entrance and inaudible in the hall. At the same time, noise rules mean loudspeakers must be controlled after 10 pm. UBM helps trusts and committees get every word heard inside, without disturbing the neighbourhood outside.
