Useful Links - Acoustics and Room calcs

Postby Digipenguin » Fri Sep 03, 2004 3:49 pm

Here are some useful links I have put together over the span of the last couple studio constructions. There are a ton more but I found these the most helpful. There is no definitive website for acoustics as there are so many facets, many of which are still debated. I would have liked to link to a site about proper measurement procedures specifically but alas I have not uncovered such a site during my studies. Perhaps an SOS article is warranted? Most of the information I have obtained pertaining to proper measurement is through forums such as this and, invariably, through trial and error. (Mostly error )

Enjoy!

Excellent. I'll add a link from the page you just posted up in the MRT forum.

There are some good explanations on room acoustics, along with some nice online acoustic calculation programs, and also some of the whys and wherefors on speaker placement (the latter of which comes up a lot around here) in this site:

http://www.mhsoft.nl/RoomAcoustic.asp

A bunch of calculators for acoustics, speaker design, digital recording time, etc. here:

Thanks guys, some good links there and the making of a good reference list. I've made this a sticky topic so that it doesn't get lost when things get busy.

Some of the references on that web page are out of date, although the technical content appears to be correct.

I used it last year Martin As I mentioned in another thread today, for fine-tuning the acoustics in my studio

Haven't got around to reading your item yet, the mag only turned up a few days ago...

Yes. Excellent software. I should have put in my post, though, that all the links are for either freeware or shareware.

I should also add that while Ethan's 'Modecalc' is small and quick and does not does not require Excel as many of the other room calculators do, that it does not do tangential or axial modes.

i just downloaded this and its GREAT

its a real-time spectrum analyser for Pocket PC.

so if you have a PDA you can turn it into an RTA. demo version works for 60 seconds at a time (you can run it again after 60 seconds are up) and full version is £20.

If you need reliable sound insulation and absorption coefficient data, you can download the BB93 database, published by the government , the acoustic standard for schools.

http://www.teachernet.gov.uk/docbank/index.cfm?id=5794

and a calculator for RTs and sound insulation from BRE using this data (Building Research Establishment ) from here; again funded by the government (dfes)

http://www.projects.bre.co.uk/envdiv/school_acoustics/

should hopefully be able to trust the government

Macintosh Room Analysis and other Software

Postby DanDan » Thu Mar 04, 2010 2:05 am

Looks like someone needs to stand up for Macintoshs here....

FuzzMeasure Pro is one of the few Mac Room (and other) Analysis programs. Typical Mac style, it is very easy to use. However it is extremely competent and stable. Very reasonable pricing also.
http://supermegaultragroovy.com/products/FuzzMeasure/

SignalSuite is another very useful Mac offering. As well as every imaginable type of noise and signal, it can generate sines and sine sweeps without the frequency jumps and glitches that DAW plug-ins often have. Useful to zero right into those room modes. http://www.faberacoustical.com/products/signalsuite/

LabMeter, a realtime frequency meter, also instrument tuners and lots more at http://www.rustykat.com/

Best Regards, DanDan

I've been looking for calculators for diffusers, QRDude seem's (from forum comments) to be quite good but PC only.

http://www.subwoofer-builder.com/qrdude.htm


Anyone know of any that'll work on a Mac?

I'd really like to know how far away a diffuser needs to be from the listener (I assume this changes with depth of the diffuser?).
