How can we reduce the echo in auditorium?
 Change the flooring of the auditorium. Changing to a soft surface like carpet absorbs sound waves.
Place rugs on top of hard flooring. If you do not want to replace the entire floor of the place, you can just add rugs to the floor to get the same echo muffling effect.

Install acoustic panels on the walls. These upholstered panels absorb sound waves before they can bounce off the solid surface walls.

Use soundproofing insulation. If you are building or remodeling a church, use special soundproofing insulation behind the drywall. This negates the need for acoustic panels.

Utilize hanging baffles. These are similar to acoustic panels except that they hang from the ceiling and are used in areas where there are severe noise problems. They are made from cotton fibers that absorb sound waves.
