micmic, 28 April 2009Hi John, Maybe I'm blind 8) but I can't find any information about your acoustic hangers...??? What dimensions are they and what kind if wood and wich kind of…
Soundman2020, 13 May 2009I seem to recall similar comments from Eric Desart on another forum, about there not being much research on hangers, and the little bit there is being inconclusive. If I…
Soundman2020, 14 May 2009Now there's an idea! Oyster-cage acoustic bass traps! :) :yahoo: The aesthetics might be a bit strange, though.... :shock: Seriously, that sounds like a good…
John Sayers, 14 May 2009Stuart - as I see it there are two ways to use them, thus mount them. In the model I gave the corner hangers is the corner trap method where the sound goes into the…
Soundman2020, 14 May 2009Thanks John! That makes a lot of sense, and gives me a first "empirical" rule about hangers: If they work best at modal points, then they must be velocity-based, not…
Soundman2020, 15 May 2009Yeah, I guess I wasn't to clear about that! I'm thinking out loud about my room, but not explaining my thoughts too well... What I mean is this: Imagine a bunch of…
Soundman2020, 15 May 2009Thanks John! That makes sense. OK, so I guess I'll see if I can re-figure how to make my hangers as large as possible, but a depth of 3-4 feet at the back would be…

micmic, 19 May 2009Hi John and all of you. A attached some pictures of the hangers I made for the studio I designed. There are seven on each site. 2.5 Meters high and the width varies from…
micmic, 29 June 2009Hi All, I've placed my acoustic hangers and diffuser in the back. (See above.) But when I'm on he mix position, I have (too)much sub low and when I listening in the back…
micmic, 6 July 2009High John,Ro and the rest... Getting back to my standing wave problem. Can I treat the front wall(that's a blind wall) and side walls, instead of the back wall where the…

John Sayers, 26 July 2009doesn't look like it Lief. this is what the stuff I use looks like homosote.jpg It's also called tack board or pin board and is used as a backing for notice boards..

Soundman2020, 12 June 2013Depends what part of the room you are talking about. If you are talking about hangers under speaker soffits, then hang them close so you can get plenty in, with just a…

John Sayers, 12 January 2015Anton - hangers take up a lot of space - they typically are either in the ceiling above a false ceiling or in a rear wall behind a cloth wall. I'm now using a new design…
Soundman2020, 2 February 2015As John said in the post, they are slot resonators, tuned to the range 30 to 100 Hz. I think John's point was that, whereas he used to use hangers almost exclusively in…
Soundman2020, 13 May 2015Hi "garysjo". Please read the forum rules for posting (click here) . You seem to be missing a couple of things! :) That said, it sounds like you have the typical…
Soundman2020, 25 July 2016It's always good to update a thread based on empirical results, with actual theory and laboratory testing! It turns out that in 2009 a group of acousticians actually did…
Soundman2020, 16 February 2017Hi Keith. Please read the forum rules for posting (click here) . You seem to be missing a couple of things! :) John already did share! He gave you the exact dimensions…
Soundman2020, 16 February 2017:thu: You fixed it! Location in profile is The Big One! :) It's fairly easy to tell the difference in most cases. Modes are standing waves related to room dimensions,…
Soundman2020, 23 February 2017Here's how it works: Each "mode" is just a frequency where the wavelength fits in perfectly between some dimension of the room. So each time the wave completes a circuit…
Soundman2020, 24 February 2017OK, I took a look at your data, and you have both! You very definitely have an SBIR problem of some type, clearly visible in the sequence of readings with the speaker at…

Soundman2020, 31 August 2017Hi Fred, and Welcome! :) And they work! This comment comes from one of my customers who recently installed hangers in his new room: "Wow these hangers are amazing. I…
Soundman2020, 9 September 2017Excellent! As soon as you have your new thread, please place a link in your first post there back to your first post here, so people can follow things better, and also…
Soundman2020, 25 May 2018WRONG! The article does NOT even mention the type of acoustic hangers that this thread is all about!!! And that is pretty darn obvious, just from looking at the last few…
Paulus87, 14 July 2018Cork is a really expensive way to go, it would work well but unless you can get it for really cheap (such as a job lot of notice boards from an office clear out or…

Paulus87, 17 December 2019I actually think we can get better results if we construct hangers with a much denser core, such as 12-18mm plywood/MDF. Philip Newell even builds them from varying…

Paulus87, 14 March 2020For my hangers I used very fluffy low gfr insulation @150mm thick. I attempted to glue it on to the homasote at first but it was a disaster... I can imagine it being…
Paulus87, 29 May 2020Use mdf if you’re going to hang them at an angle - the fibreboard will bow unless supported with some barren supports on each hanger, and will require more fixings so…
Paulus87, 29 May 2020They will work whether angled or not but Philip Newell and Tom Hidley (pioneer of the hangers) angle them towards the speakers on the ceiling, so the ones closest to the…
Paulus87, 1 October 2020I have a couple of academic papers on hangers which contain a lot of info and data, as well as how to construct them properly. Please PM your e-mail and I will send it…

Paulus87, 29 October 2020OSB is ok, chipboard is what Newell recommends. The way I do it is use large circular washers and screws to attach the insulation to the boards, it doesn't matter too…
gullfo, 4 March 2021technically "hangers" are a type of broadband absorber - the low density fiberboard provides both absorption and waveguide functions. the waveguide effect lengthens the…
Paulus87, 21 August 2021Homasote is not needed or even advisable (despite the numerous claims on this forum of it being some sort of acoustic gold dust) the way which the hangers works means…
Paulus87, 21 August 2021There is a paper done on the hangers, it tells you how to approximate the frequency range of absorption, I've posted this numerous times:…
