Amplified noise control vs. hubbub
Controlling amplified music at a wedding venue can be relatively simple when implementing the correct acoustic design and management mitigation steps, because recorded amplified music in general, is constant when you have a fixed volume level.
Controlling the hubbub (loud noise or many voices talking at once), however, presents more of a challenge. Wedding guests can be raucous or meek in equal measure and a hilarious best man/women speech can raise the laughter and applause levels without warning.
