Best option for reducing reverb in large rooms....

I have a few business' that I go into that have a good size room for me to record video in that I'm always trying to reduce the room bass/reverb of. The area size used, not room, is at least around 10x20. I'm trying to 1)contain sound and reduce room reverb/echo 2)reduce office/traffice noise if possible

I figured I could go with one of these $160 options:

Just hang up the sheets around on light stands. Probably one on each side and the other on the most problematic area. Might need alot of stands though?

Figure out a way to attach the panel to a light stand. And then just set up in different spots.

Any suggestions?
 
But WHAT are you recording? Are you talking about a person delivering a presentation? Are you talking about a group discussion of 100 people?

Quite often the solution is to improve the direct/ambient ratio by using an appropriate microphone and getting it MUCH closer to the sound source (the presenter's mouth).
 
There are three ways:

1. Get the mic closer.
2. Use a mic with more directionality.
3. Use absorbing material.

If you are already using a quite directional mic as close as you can, then there are several methods of sound proofing a space. Make a search - it's been discussed. Don't forget the floor and ceiling.
 
'Moving blankets' is probably the best 'cheap and easy' solution. The 'soundproofing' sheets may be heavy, especially if lined with lead, which is common for sound 'blocking'.
In a large room presentation with an audience, a headset mic on the presenter would be a good choice.

BTW, HarborFrieght has 72" x 80" Mover's Blanket on sale this week. 9.99, on Sale 7.99, only $4.99 with coupon.
 
What Richard said. First thing you do is get the mic as close to the speaker's mouth as possible. S/N uber alles.

If you are going down the road of hanging sound absorption, don't fall into the trap of placing it right up against the walls, unless it's designed for that. Sound blankets and the like often work best if a foot or more off the wall.

Audiophiles are often praising Tube Traps. Good stuff, does a good job killing off reflections.
 
Any room with multiples in the dimensions........BAD. 10 by 20 jumped out at me. It sets up massive nodes and antinodes and can inject comb filtering through first order reflections.
 
The OP never returned. We don' really know whether it is a recording problem and/or a reinforcement problem.
You can get away with less expensive solutions if reinforcement isn't involved.
