Title: Room Treatment
Post by: cyberdraven on Jul 28, 2015 at 09:49 AM
Guys, lets have a thread to exchange info and practices that you actually done with your room.  Of course, there's a lot of reading in the net on how to, but let us deal with pdvd style in room treatment.

Please share how you treated the room and what was the results.  What are your room restrictions and how did you deal about it?  What type of acoustic treatment did you use and why?  How did you evaluate effectiveness? 

Picture builds are much much appreciated.

Thanks

Paeng

bro.

listening area around 20 sq. mtrs. height is about 3 mtrs. 

problem: comment of one auditioner before was the echoing. 

adjustments made: 

1) vertical banners using thick center table top, two at the back and three at the front.
2) carpet at the center of the listening area.

I do not have bass absorber and sound traps, not into it yet.  it collects dusts, requires detailed cleaning and occupies space. 

vertical banners requires a few dusting only while the carpet requires some vacuuming, it's also a space saver since you just have to hang it on the wall and the aesthetics of the banners (these are hard to find weaves by our tribes from Zambo).

you have first hand experience on the result of the adjustments.   ;D

Would like to seek help from those who have experience in sound treatment. This is my first time to use sound treatment. Before it was just curtains, carpets etc since I co-exist with my better half and she has a say in the decor.  This time around I was allowed to use sound treatment since the room is solely for that purpose alone...watching movies, playing games, PC productivity etc.  My main stereo rig will not be used here.

I looked around for noise absorbing material and I would like to avoid Rockwool due to the health hazards that it imposes. 

My question to you guys would be this: can these be used as DIY sound absorbers?  Bought 2 boxes from Home Depot clearance sale in the US and had it shipped here.  That's about 50 panels measuring  24" x 24" x 1.5".

(https://s-media-cache-ak0.pinimg.com/originals/3c/67/74/3c67748e04db53e495ec7fd580aeb708.jpg)

I plan on adding the sound control treatment inside my HT/Media Room which contains my 6.1HT  and my DJ/productivity/gaming rig PC. Same PC is used by my wife during evening since she works from home.

Any help will be appreciated....specially from who have already experienced DIY'ing their rooms and of course from the pro's like Ricky, Froot etc.

Sir I think those are designed for in ceiling, meaning sa loob ng gubida ba tawag dun? Sa 1st floor or basement lagay para mablock ang sound galing sa floor sa taas. Plus I doubt the thermal insulating purpose, sa heating inside the room naman block nya makalabas para tipid sa electricity during winter, pero kung heat at cold temp sya applicable then ok na seguro.

yup they recommend this for the ceiling however it also has good sound absorbing characteristics (see below) and for the price I got it...its a steal.  Health friendly to boot. SRP of this is around $225.00 for a box of 25 pcs (24" x 24" x 1.5"). I got it for clearance  (damaged box nga lang).

    Size: 2 ft. x 2 ft. x 1.5 in. (Nominal)
    Color: White
    Material: Thermal-Bonded Polyester
    Weight: 0.80 lbs.
    Odor free, moisture-resistant, does not promote mold or fungi growth
    Dust free, itch free, fiber glass free!
    Thermal-bonded polyester that will not lose body over time like fiberglass
    Coverage: 4 sq. ft. per Soniguard piece
    Noise Reduction Control: 0.50 with 0.013" tiles, 0.30 with 0.030" tiles
    Sound Transmission Class: 13 with 0.013" tiles, 18 with 0.030" tiles

Just an update. 2017 was when I "upgraded " my system by re-allocating a dedicated and treated room to house my HT/Music system.  Fast forward 2020 and in hindsight its the best upgrade that I made in all of my audio and HT journey and its not even the most expensive upgrade.  Now that 6 months na ako WFH, I have so much time enjoying the system daily.  Started this journey in the mid 90's and now looking back, I should have prioritized a treated room to house the system a long time ago.

The best thing to do in a dedicated stereo/cinema mancave & as Master Nelson said cheaper in the long run. But this will be the hardest thing to do if we make this our last priority especially if those HAEVY METAL gears are already in place  ;D
Title: Re: Room Treatment
Post by: synchro_01 on Aug 10, 2020 at 12:51 PM
Very true. it took me years to finally realize the possible performance jump in my gears by way of acoustic treatments and allocating a dedicated room to house the system. Siguro 99 out of 100 Audio/HT hobbyists buy the gears first and then embark on the endless upgrade path trying to find incremental performance jump on every upgrade not knowing that the general environment in which the component plays to affects the outcome tremendously.

Interesting. If only I had a room available to use for dedicated listening/HT.

Anyway, any recommendations for broad-band bass traps that are locally available?

Which product do you recommend for corner bass traps?
Title: Re: Room Treatment
Post by: Nelson de Leon on Aug 11, 2020 at 01:53 PM
Which product do you recommend for corner bass traps?

Sir I'm really not a fan of bass traps in its capability to significantly reduce the low frequencies. For home theatre application I believe most watchers would watch the movies with slightly boosted low frequencies to make the experience more immersive. And if there are rattling issues, i would recommend fixing the rattling issue so you can have a better "bass". Or lower the sub gain if you want to "trap" the bass. Or perhaps EQ the lower frequencies.

But for 2 channel applications, that is a different topic. Instead of bass traps I would recommend treating the corners with custom made thick absorber panels or thick sound absorbers. It would have the same effect as the bass traps.

Master Nelson,

Do you think buying the right sized speaker for the room (2 channel) will altogether avoid the use and necessity of bass traps?  I think bass is harder to tame than mid and high frequencies so if one buys the wrong size floorstanders and puts it in a room where it can over power the room itself then it becomes an issue.

It can sir but not necessarily a guarantee... In my experience the benefits of the correct speaker size would be proper imaging in relation to the room, more balanced tonality, yes tonality also includes the low frequencies. It's not a general rule because there are also speakers that are bass heavy to begin with. Plus room modes pa din.

Thanks for the info. Best siguro to really test the speaker in the room prior to purchase.

Thank you for the solid advice. I'll definitely look into it.

My main purpose is for 2-channel music and I wanted to get rid of the occasional boominess by attenuating some of the bass frequency peaks and dips while preserving overall bass levels. So basically I want to flatten the bass frequency curve with EQ as a last resort.

If you only have 1-2 frequencies you want to control, you can make helmholtz resonators.

Talking of speakers in relation to the room, I wonder what are benefits if the stereo speaker drivers are installed in the front wall i.e. the front wall itself is the baffle.

Benefits? stealth look. Malinis tingnan because in wall speakers are designed really to blend in the decor however you probably will lose the sonic illusion of depth. Sa US uso yang set up na yan.  pre built in wall speakers are available from many reputable speaker manufacturers. Madali for them to install those because their walls are normally not concrete unlike here.

IN-WALL good for HT use if we like to have clean look w/out those bulky speakers all around the room. I think ok lang yung IN-WALL para sa HT coz usually it just for effects but for stereo they aren't capable of high-quality sound. Just my 2 cents.

Title: Re: Room Treatment
Post by: at_sunset_blvd on Aug 12, 2020 at 07:33 AM
Cars in the 80's usually has those infinite baffle system making the entire baggage compartment as the box. I don't know if that will ever work w/ home systems. Maybe if there's a basement & the under flooring is made of wood then possibly install the sub speakers in the basement then the bass flow to a duct/vent towards the intended area. parang pangit siguro ang sound nito & very tedious to do but maybe at least uni-directional ang bass waves  ;D
