Suze Posted January 27, 2005 Share Posted January 27, 2005 Hi, I need help! I am writing a dissertation on how to acoustically design a space and how to improvea bad acoustic space. I wondered if anyone out there ahd any information that could help me or suggest any one I should talk to. I've arrange to go and talk to people at the National, The Albert Hall, Orbital and I'm trying to get info out of the people that are doing the redesign of the Sydeny Opera House and the people that built the sage concert hall in Newcastle. Any more ideas? Or ideas of books I should read? :) ;) Link to comment Share on other sites More sharing options...

Orchytech Posted January 28, 2005 Share Posted January 28, 2005 LSO St Luke's (where I work) has an adjustable acoustic so that we can rehearse a full Symphony Orchestra in the morning and then record a piano recital in the afternoon. The building is a converted 18th century church. The system was designed by Kirkegaard Associates in Chicago who also designed the Barbican's acoustics and who are now finishing on the Festival Hall. http://www.kirkegaard.com/about.htm Triple E built the adjustable banners and there was an article on them last year in Lighting and Sound International. It might be of some use if you can find it. Let me know if you want anymore info or a demo Orchytech. Link to comment Share on other sites More sharing options...
ljstevens Posted January 28, 2005 Share Posted January 28, 2005 Hi look into brigdewater hall manchester thats ment to be one of the most advanced acoustic spaces in the country and I think wigwam acoustic did the install and design so it could be worth giving them a bell Link to comment Share on other sites More sharing options...
Modge Posted January 28, 2005 Share Posted January 28, 2005 You could try the birmingham Symphony Hall, they apprantly have the ability to vary there accoutics - accoutic chambers with mechanical doors in front of them controling how open they are. Another usefull source might actaully be the academic department in which I'm currently doing my degree: www.eee.bham.ac.uk, they do some research into accoutics Link to comment Share on other sites More sharing options...
paulears Posted January 28, 2005 Share Posted January 28, 2005 The subject is in the archives of the theatre-sound list, gets a bit deep sometimes when someone is discussing the finer points of a 300K desk, but good on quality.

Jivemaster Posted January 28, 2005 Share Posted January 28, 2005 No-one likes their space to be assigned Bad in terms of acoustics. There are many norms and definitions of good, some conflicting, hence the adjustable spaces of today. A reverb decay time of 2 secs is fine for choral music in a big church or cathedral but a recording studio will have a reverb time more like 0.2 secs. Radio and TV studios use reverb times to suit the programming made there some radio drama studios have a live end and a dead end for differing dramatic purposes. -- and reverb is only a small part of acoustics! The late CLS Gilford was a acoustic specialist for the BBC at Kingswood Warren and wrote books on both auditoria and studio acoustics sadly all out of print but searchable as second hand. They are 50s to 70s technology but the acoustics are the same only the equipment is dated! They were imprints of the IEE so there is a copy in their library stack available for visitors to study there ( Savoy Place London ) There is a book called The Master Acoustics Handbook available in libraries and I think Terralec sell it Link to comment Share on other sites More sharing options...

Mr.Si Posted January 28, 2005 Share Posted January 28, 2005 May I ask what sort of acoustic space you are trying to create? - what is it now?- what do you want to use it for?- what are your main problems? - High RT's? Poor Speech intelligibility? Specific frequencies problems? What are the surfaces of the rooms? and their areas etc - plus, volume of room? If you're wanting to produce a normal kind of room, there is something called the "GOLDEN RATIO" - the ratio of the length to the width to the height. it is supposed to provide the volume with the least room modes. It is defined as 1 : 1 1/3 : 1 2/3 But that is for cuboids and I have a hunch you're not dealing with such a space, but if anyone has a situation like that, it is a useful thing to remember.

Suze Posted January 30, 2005 Author Share Posted January 30, 2005 Orchytech-thats great - thank you! I went on the Kiregaard web site, do you have an email address of anyone there so I can get some more information on the design - and a demo would be great if it woudn't be too much hassle Link to comment Share on other sites More sharing options...
