What is a cost effective way to create a sound barrier?
I manage a hotel that has a restaurant attached to it. The Restaurant is leased out to a separate entity but they plan on having live entertainment. The problem is that music always ends up disturbing the guests that are closest to the Restaurant. The previous leaser did not care but the new leaser does and we are trying to come up with a cost effective way to create a sound barrier effective enough to keep from disturbing the hotel guests. The sound proofing sites I have been to are too expensive for a start up business. I've been doing a lot of searching and come up with the idea of building a Plexiglas shield to deflect the sound away from the hotel. Is this idea going to work or do I need to go back to the drawing board?

Soundproofing is expensive. There is simply no better way to say it.
If the adjoining wall is a hollow drywall based wall, then add drywall to it. A two inch thick layer of drywall will kill a lot of sound.
It is hard to say what would work the best without seeing the situation. A shield could block sound traveling through air. But a connected building will receive most of the sound through the woodwork. Remember two things 1) sound travels through solid material better than air. 2) Sound just like anything else requires energy to move through things. The more mass in the way, the more energy is required. Where there is no mass, sound can't go. Vacuum window panes are soundproof.

I've been faced with the same issue a few times, and here's what I've learned. Plexiglas is a membrane that is rigid. This would act as a diaphragm, transferring the sound wave to the other side. I have seen people use that 4' x 8' sheets of hard styrene from home deephole to soundproof with no luck because of the same transfer scenario. The idea is to loose the sound wave. There is a few brands of drywall that have a membrane of gel that deadens sound waves. I used one brand a while ago that I think was named "Quietrock", which worked quite well. I installed it between two bathrooms, and if you tap it with your knuckle, it sounds like solid rock. The drawback, of course, is that it cost around 90.00 a sheet! Another cheaper solution, which would be better if you have a large wall to deaden, would be a 2x6 wall,with regular fiberglass insulation (non-transferring), then add as many layers of drywall to one side, at least 4, and at least 2 to the other. Even better if you can find a rubber sheet membrane that you could sandwich between a few of the drywall layers. Good luck with your noise.
