  1. Room absorption test with Rockwool and REW 5.18

    REW Forum
    I have a kind of dice living room (5,4m (width) x 5,04m (length) x 3,7m (high) with a lot of hard reflections. And a wife that don’t like to convert it to a studio :) I did some tests with rockwool solids in the corners to create a DIY bass trap with a global absorption. The result however is...

  3. Built my first absorption panels

    Home Audio Acoustics
    Nothing fancy but built a few panels today. I won't need too much more absorption but this will do for now. I'll start building some diffusion stuff next. Time for trial/error on placement.
  4. Front wall/Rear wall absorption ideas

    Home Audio Acoustics
    I have a 16'x26' room. Using AT screen. Going with 7.2 set up. One sub will initially be placed behind the screen slightly off center and the other in the rear of the room (not in the corner) about 8' off of rear wall and 2' off of wall. (next to front row of seats). So, that's the set up so far...
  5. Building my own 2'x4' absorption panels... is 8LB density too dense?

    Home Audio Acoustics
    Have a local company where I can buy 2x4 slabs of 2" thick 8lb density minwool panels for $0.52sqft. They come 6 panels to a box of 48sqft total and the price is phenomenal at $24.96 a box. Gonna pick up 3 or 4 boxes tomorrow depending on the verdict here. is 8lb density too thick to absorb...
  6. List of absorption coefficients

    Home Audio Acoustics
    Hi, i am looking for an extensive listing of absorption coefficients to be used in a simulation program. What i have found so far are these (2nd one is in german, sorry): http://www.acousticalsurfaces.com/acoustic_IOI/101_13.htm...
  7. Translucent curtains with ~0.65 noise absorption - too good to be true?

    Home Audio Acoustics
    Hi all, I have a large living room that has full height sliding glass panels on one and a half sides, marble floor, plaster ceiling. It has very bad reverberation, very poor speech intelligibility even if it's just 2 persons trying to have a normal conversation. I plan to cover some walls with...
  8. Absorption of HT seats question

    Home Audio Acoustics
    In a theater, the sound decay characteristics should remain stable, whether one or all the seats are occupied. Although it is less important in a small room with a limited number of seats, we must take into account the sound absorption of the chairs. Reflective surfaces such as leather, or more...
  9. Tackling Acoustic Treatment

    Home Audio Acoustics
    Hi, I'm Oswald. This is my first post so let me briefly introduce myself. I've been doing everything on my own for about 8 years (writing music, playing instr., rec vocals, DAW composing/sequencing/engineering) and currently, I am majoring in music composition. I have worked with a basic setup...
  10. using REW to measure absorption in a room

    REW Forum
    Hi guys, I've been using REW for a while, but have recently done some research into room absorption, and the concept of measuring overall absorption in a room as a target for applying treatment, and I'm keen to use REW to assist in my measurements. Applying appropriate treatment based on the...
  11. question about absorption material

    Home Audio Acoustics
    I run the equalizer/mixer at my church we have a 100ft long X 60ft wide X15ft tall room i am having a hard time with mid to high rand frequencies echoing off the back wall i wont to put sound absoption material in I herd you can use ac duct building material but what kind is the best for...
  12. The distribution of absorptive panels

    Home Audio Acoustics
    I need advice on the distribution of absorptive panels in rooms that need a very low reverberation time (rehearsal rooms for pop/rock music that is very loud). I work at a music college that has just got use of four new rehearsal rooms. They installed absorptive panels that are very large -...
  13. Absorption- Quality vs Quantity?

    Home Audio Acoustics
    or maybe it's NRC vs SQFT of coverage? I'm looking to adventure into treating my movie room and like many have a budget, with so many options out there I guess I was looking for some guidance. I know... it always "depends on the situation". But is there any kind of general rule with setting up...
  14. Building some DIY absorption panels. Need help with questions.

    Home Audio Acoustics
    I have decided to build some absorbtion panals for the first reflection points and possibly some more for the front wall. I have some questions that I can't seem to find the answer for, so if anyone can give me some answers to these questions, then I will be greatful. First, is regular roxul...
  15. My DIY absorption panels

    Home Audio Acoustics
    After a lot of reading and "listening" here on HTS and the GIK website, and a couple others including Rives Audio, I have begun the journey of room treatment. I understand that measurement and analysis is important to this process, and do intend to do that at some time in the future, however...
  16. Absorption above flexible ceiling tiles

    Home Audio Acoustics
    I am treating a small mixing room and need to cover the ceiling to conceal air ducts and plenums primarily for aesthetic reasons, but also to prevent the soft-side ducts from acting like high-Q traps - the 1/4 wave narrow-band suck-outs I measured were exact 4x multiples of the duct diameters of...
  17. Finally added some absorption

    Home Audio Acoustics
    Well I finally got around to it and made some mini-chunks (12x12x17) in my front corners and a couple 2" 4x2 panels for the side wall first reflection points. I used 6 lb/ft³ mineral wool. I faced the corner chunks and backed the wall panels with some left over laminate underlay that's made from...
  18. Absorption coefficients

    Home Audio Acoustics
    I thought I saw a link to a chart from this site, but now I can't find it--- does anyone know where I can find an audio-treatment focused chart of audio absorption coefficients for various materials and thicknesses. There's something similar easily found on Google, but that's more focused on...
  19. Front Wall Absorption

    Home Audio Acoustics
    So my second listening room, aka the bedroom, was in dire need of treatment. Not much placement options available, so I decided to just stick things where they had to be, Took a series of measurements, added a 50"H X 80"W X 12"D absorber behind the speakers and then added a 50"H X 24"W X 18"D...
  20. calculating absorption coefficients

    Home Audio Acoustics
    I have purchased three different materials: a high density rock wool, owens-corning 703 and 705. I have also acquired a measurement mic and downloaded room EQ wizard. I am planning to put together these materials in different combinations of 4" panels and compare measurements (for example, 4"...
