Sound Proof Movable Partitions


Guy Tec

Recommended Posts

Hi not sure if any one can help but I work at a college as a P Arts Technician and have been tasked with the job of finding a reasonable soundproof partition between a studio theatre space and a dance studio .The plan is to cut down on sound bleed during lessons but if we want to we can open up the wall and use the dance studio as an auditorium the opening is about 4m high and about 8m wide

 

any thought ??

Guy,

 

you need a retractable acoustic partition. You'll also need to check the level of flanking transmissions in the site survey, as these can seriously reduce the noise reduction capability of the partition.

 

The best devices can achieve around 50 - 55dB reduction, which looks very good, but would mean a rock band would still be audible on the other side.

 

Cost wise, a 4m x 8m sliding acoustic partition could easily cost £10k to £20k, more if a support structure has to be fitted.

These Guys have alot of good products.

 

Like Simon said though, Flanking sound transmission is a huge problem, cause the sound will just find the weakest path, (ie over the wall, through ceiling tiles or via joints or something) and take much advantage of it.

 

I don't like these sorts of partition, but I guess there're other practical reasons to use them.

Yeah, don't expect total silence. I once worked in a room that was fitted with an acoustic partition that we divided up to form two venues - the only way anything near an acceptable amount of noise reduction was achieved was by buiding another dividing wall, filled with insulation, which was then lined with acoustic foam. Even then, we had some problems with things like loud PAs.

Thanks Nick ,

I am a realist and if I can just reduce the transmition of sound between what we have, which is a dance lecture in dance studio which has a small Pa 100W per Ch in a room with 6 hard reflecting walls.The one I hope to change at the moment has floor to celing glass pannels in an aluminium frames which has glass on both sides but there is no vacum between the glass so there fore not much sound attenuation .On other side a studio theatre which has stage curtains around so better with sound and also only a 70w per Ch 4 Ch system but using small rig mounted speakers but the long term plan is to open up space so that dance studio can be the auditoriom we have a prosc arch theatre space on other side.

 

Thanks for everyones input on this post Guy Douglas

At TV Centre we had concertina-type folding walls in the VT areas, so they could be divided into individual pairs of cubicles or large open-plan areas for the big sports programmes, which provided quite reasonable isolation. We didn't have 6 hard surfaces to deal with though.

 

A few years ago I put in sound & comms for a new sports & performing arts building in a big school. The music & studio suite were ok, being on a separate floor, but the leakage between the ground-floor drama studios, & between them & the sports hall was horrendous. The main culprit turned out to be the metal trunking carrying all the electrical services, which ran through all the spaces, with no attempt to control either air-borne or structure-borne sound.

You realise you're replying to a thread from 12 years ago...

 

 

I do now :( :( :(. Must go back to Specsavers !!

 

 

To be fair to Sandall, he was probably replying to the two, now hidden, spam posts which resurrected this topic.

Indeed so - as there was no note from a Mod it just looked like a reopened thread.
