I commonly like the work of Grimshaw, even though they appear to be missing too important of a detail at Patsaouoras Plaza at LAX by removing the multi-cultural dome in a proposed design. ETFE has an interesting characteristic of transparency with a membrane volume less than kg/m2 (1). Designing with ETFE can include invisible baffle layers to trap sound in a pillow on the sound side and absorb on the design side.

Grimshaw used that at the Eden Project in Cornwall
Don't know about the acoustical properties, though.

John Hayes,
It sounds like your hypothetical situation really needs a pneumatic band stand out of ETFE pillows.

On traditional city blocks that are ringed by four or five story townhouses, the back yards of the houses are usually separated by six foot high wood or brick walls.
if your neighbor has a party in their backyard, you will hear people talking and moving around. It doesn't matter whether the wall is wool or brick, the sound just comes over the top. And if your neighbor has a house near an inner corner of the block, the sound will be reflected toward you from the backs of other houses. You put up with it as just one of the trade offs for living in the city. If a neighbor has a band in once or twice s year for s birthday party, you accept that too as long as they shut down at a reasonable time.
But if s band bought s house and started playing in their own backyard every night, you and your neighbors would complain to he city to get it stopped. Short of moving them inside or enclosing their whole backyard in soundproof structure (if code permits) I don't see how outdoor music and neighbors in a residential visit could coexist
Now, none of us has seen your site That's why I suggested getting an opinion from an acoustical consultant right away. Paying for a few hours of an expert's time now may be the most economical way to get ahead.

Hi Kathleen,
I know from having worked at IBM in Poughkeepsie, that mass best stops sound. The heavier the material the better the sound deadening. When we built an isolation room to test radio frequency, it had to completely soundproof from the outside. The walls, floor and ceiling were lined with lead sheets, then anechoic foam on top of that. The anechoic foam consisted of about 3' deep spikes. It was in this anechoic chamber that they could test their equipment. You could not hear a thing outside.
In a restaurant a heavy wall, along with shrubs would act in a similar fashion. Of course agreeing to limiting db of music also wouldn't hurt. In my opinion they ruin it for me when we have to shout to hear each other, so we just avoid those places even if the food is great.
Best of luck with your project!

Hello-
Scene- Small restaurant in old mixed use DT has its rear yard butt up to a pocket of single family homes. New owner of restaurant wishes to add outdoor seating at the rear. Neighbors expressed concern about noise- owner will work out hours of operation and if or when music might be played outside- will work with neighbors and village government.
However, we have been asked to present noise control options. We showed a wall that was 6-6 high. The planning board would like to see some back up for the material choice.
Before going to an acoustical engineer, has anyone had experience in this type of question. Recommendations for a product? A place for guidance that is DIY?
Thank you
