beeros05, 2 February 2012I edit my first post here in order to be in accordance to the rules properly and also because anyone that reads this topic, must read it ALL OF IT! FROM THE START UNTIL…
Soundman2020, 2 February 2012Hi "beeros05". Welcome! I'm wondering several things about what you did there: 1) Why did you build THREE_LEAF walls ??? :shock: Are you not aware that a three-leaf wall…
beeros05, 2 February 2012Hi Stuart. The guys that made the drum room guaranteed 100% good result. I am not familiar with some terms you use i am Greek... The guys that made the drum room…
Soundman2020, 2 February 2012I hope you got that in writing! I'm just wondering: What is the purpose of this build? Do you need to isolate (soundproof) the room so that your drums can't be heard…
beeros05, 2 February 2012I wanted to make a drumroom basically in order to play and not to disturb. I went to several acoustic companies but they were asking 10-15.000€. I couldn't afford that.…
Soundman2020, 3 February 2012Yes it is: that is a three leaf-wall. The concrete is the first leaf, the first two layers of gypsum board is the second leaf, and the other two layers of gypsum board…
beeros05, 3 February 2012OK, so if i understood right you say to me that: 1) In the existing concrete walls (1st layer) to add rock-wool 2) Then leave air-gap, frame and put rock-wool again 3) 2…
Soundman2020, 4 February 2012Yes! Exactly! That's the correct way to do it. And 4 layers of gypsum board would be excellent. Probably it would be more than you need, but if you really wanted to do…
beeros05, 4 February 2012OK I got that, the rubber acts in a similar way as suspensions work in a machine vehicle. If You have a Fiat Punto you cannot use a suspension system from a Scania…
xSpace, 4 February 2012It's guaranteed in writing. I find it hard to believe that 1. those guys screwed it up this bad and 2. that you will have it torn down and rebuilt. The builder of this…
Soundman2020, 4 February 2012Exactly. Good analogy, since that's exactly what it is: A shock absorber. Maybe your best bet would be to hire a contractor who will obey your instructions, and do it…
beeros05, 4 February 2012I called the subcontractor I told him to come here because we might have problem with the construction. He came immediately I told him the things you told me. He said…
Soundman2020, 4 February 2012To be honest, I don't see how that makes any difference. Those seem to be some type of footing for the foundation, but that isn't relevant to how the wall is built. All…
beeros05, 5 February 2012Yes this is the footing of the foundation Recovered from web.archive.org — originally hosted at…
xSpace, 5 February 2012""All of the weight of the wall rests on the concrete floor anyway, and the floor rests on the foundations."" Typical wooden framing called platform framing might be the…
beeros05, 5 February 2012How is this possible? I mean will the framing be capable of carrying the load of 3-4 layers of gypsum-board? All the studio ceilings i have seen are being hanged from…
beeros05, 9 February 2012UPDATE! Some (maybe) good news... I called the subcontractor to make a new deal. I had with me a good friend who has studied Music Technology & Acoustics Science. He has…
beeros05, 11 February 2012And some not so good news. The subcontractor called me and said that he can give me written guarantee about the results only if i was going to use wooden custom doors…
Soundman2020, 12 February 2012Man, I'm really sorry to hear that. (I guess the contractor wasn't so confident about his build anymore, once he started looking into it.) It's not surprising that you…
beeros05, 12 February 2012The subcontractor came this morning to chat. I told him that i cannot work with such an unreliable person and the he should be ashamed cause he was introduced by another…
Soundman2020, 12 February 2012I hope he's willing to sign that in writing this time! That would be a reasonable deal all around. Fair enough. Then let's stay with metal framing on isolation hangers.…
beeros05, 13 February 2012It does not matter any more. I am taking the responsibility of the design/construction Fair enough. Then let's stay with metal framing on isolation hangers. So what's…
Soundman2020, 13 February 2012Actually you CAN have 100 dB! You'll just need a few million dollars to do it... :lol: Seriously it is possible: Eric Dessart (he posts here on the forum occasionally)…
beeros05, 13 February 2012So space-wise i cant make a construction that can absorb fairly bass guitar frequencies. But I could make a bass guitar amp "riser" like this drum riser (after i make…

beeros05, 28 February 2012Update... The room has been dissembled in order to be rebuild. I went today in a acoustic company which also manufactures anti-vibrating suspensions, pads etc. I…
Soundman2020, 29 February 2012Once again, we get back to the original question that you have not yet answered: WHY DO YOU THINK THAT YOU NEED TO FLOAT YOUR FLOOR? There are very, very few valid…
beeros05, 29 February 2012Yes i've read the document, more that once. It is all clear to me but when i went to this company the guys there told me that making a drum riser with…
beeros05, 1 March 2012Mate, i really appreciate your concern and Stuart's and that's why i keep posting here with you guys, because your opinion is important for me. I don't doubt you or…
Soundman2020, 1 March 2012Let me try to understand this: You are taking the word of a salesman who really wants to sell you his product, even though his specifications defy the laws of physics,…
beeros05, 1 March 2012If i would not take your words guys i would not post here. I do take your word because you saved my ass and my pocket! And i REALLY appreciate it! But we must place in…
Soundman2020, 1 March 2012Right here, paragraph 13: viewtopic.php?f=2&t=17363&start=7 Here's the paragraph: Then I'm confused once again, because things keep on changing here! Are you trying to…
beeros05, 1 March 2012I probably missed that... A floating floor needs mass i got that its ok. The purpose is to have a more "proper" decoupling floor. He proposed me to put double pads 2…
xSpace, 3 March 2012So is the goal now, Antonios, to construct a decoupled floor (of wood damped underneath) and floated walls that do NOT sit on the wooden floor? While I would still have…

Soundman2020, 8 March 2012Hi Antonios, and welcome to the forum! Thank you for joining in, and explaining your point of view. And please do stick around! Occasionally we do get people from Greece…
Soundman2020, 8 March 2012That's sort of the idea, yes, but the tube doesn't need to go in the box. Here are a few examples of how to do HVAC silencers:…

Soundman2020, 10 March 2012Thanks for the translation! That makes sense. And once again, we see that they specify concrete... The floated floor in this case is 5cm of concrete with tiles on top.…
beeros05, 10 March 2012You cant imagine what i have been going through, how much stress and disappointment i felt because of this guy! I have to supervise this guy all the time. Its worse than…
beeros05, 10 March 2012Update, Sound-check No 2 So i brought a friend to play some drums. I went to the ground floor at my parent's apartment. Clearly there were no vibrations AT ALL on the…
Soundman2020, 11 March 2012I can imagine... But think of it this way: At least you are on the right track now, you can see that what you are doing is working already (even though it isn't finished…
beeros05, 11 March 20126*6cm, 2.5cm height but 2 layers. That makes 6x6x5. It is the same pad shown in the case study i translated. You think so? Why not! Plus i am i good salesman as well if…
Soundman2020, 11 March 2012OK, that's what I suspected. That's normal. You normally can hear low frequencies (bass) better when you get close to walls. This is sometimes called "bass build up". It…
beeros05, 13 March 2012Hi again, i uploaded a drawing that has to do with the elastic pads placement. According to Antonis 5.5 pieces / m2 should be placed approximately but at the drum-kit's…
beeros05, 16 March 2012Floor Elastic Pads Vibro EP RED 6x6x5 and rock-wool 75kg/m3. The distance between the pads is 60cm approximately and 5.5 pieces/m2 are placed approximately. In the…
Soundman2020, 21 March 2012I reckon that he means you need to use a sound level meter to find out how much isolation you are getting! Objective numbers, not subjective opinions. And if you are…
beeros05, 21 March 2012Ok got that but i have not installed doors yet and i do not know when i will do that 'cause i am out of budget. The "best" i can do right know is to use some left over…
beeros05, 29 March 2012We did the measurements roughly 'cause my friend saw and used the program at the same time. He proposed me to do the measurements again in a couple of days 'cause he…
Soundman2020, 29 March 2012It means you have a problem and need some acoustic treatment!!! Yes, you should really use an omni mic, and yes your friend needs some more time to learn the software a…
beeros05, 29 March 2012Yes, no treatment at all. I have not even installed doors! I have some left over gypsum-boards and i will use them by making 3 layer "covers". One inside one outside I…
Soundman2020, 29 March 2012Exactly. In English, those are called "standing waves" or "modes", and they are a direct result of the dimensions of the room. Certain frequencies, where the wave fits…

beeros05, 29 March 20122.85 L, 2.45 W, 2.05 H. Damn, i thought so...how deep? 30-40cm would be OK? Sorry...forgot to mention it. The classic panels with wooden frame, rock-wool covered with…
Soundman2020, 30 March 2012OK, so your first three axial modes are at 60.4 Hz, 70.3 Hz, and 84 Hz. Then you have three tangential modes at 92.7 Hz., 103.5 Hz, and 109.5 Hz. And yes, those are all…
beeros05, 30 March 2012I tune all of my drum-heads in medium-low tension I did this room mostly for practicing and rehearsing but in the near future i will do drum tracking as well IF i have…
Soundman2020, 30 March 2012OK, it's good that you mentioned that, as there are some things that you can do to make it a bit better for tracking. It won't be fantastic for tracking drums, due to…
beeros05, 30 March 2012Things like what? Or it's too early to talk about these stuff? No one in the band is a "perfect" musician. NO-ONE! We are Motorhead-style band and it is going to stay…
beeros05, 4 April 2012Stuart! I made a mistake...i hope it is not a huge one! The dimensions of the room are 3.85 L x 2.45 W x 2.05 H. Hence, the room ratios change...hence i might not be…
Soundman2020, 4 April 2012Yes, the 1 m DOES drastically change the ratio! Even a few cm can make a difference. So your ratio now gets far away from the good one you had. But fortunately, it gets…
beeros05, 11 April 2012Some friends proposed me to install "Hormann" Doors. Hormann is a company that makes garage doors and industrial doors. Their industrial doors are soundproof rated and…
beeros05, 7 July 2012Hey guys, long time... I made some bass traps and installed some panels here are some pics Image not preserved: IMG_2041.JPG Image not preserved: IMG_2038.JPG Image not…
Soundman2020, 7 July 2012Good to see you back again! :) There's a program called "REW" ("Room Eq Wizard") that you can download for free, and use to run a complete acoustic analysis on your…
beeros05, 7 July 2012Good to find you back here bro! I know the program, i had done some tests remember? But we didn't have omnidirectional mic. I dont know if i will run the tests again, we…
beeros05, 20 October 2012Regarding the doors... I will make (probably) 2 solid core doors triple plied MDF. The basic core will be 4cm thick, after that 3cm layer and another layer of 2cm. I…
beeros05, 26 November 2012I am going to order next week aluminum doors with triplex laminated glass. The glass on the exterior door will be 1.5cm thick and on the interior 1.3cm thick. The…
beeros05, 29 January 2013Hi guys! Today I installed the doors. I just came from the drum room. My brother was outside the room and told me that there is sth like 80% noise reduction. I have not…
Soundman2020, 29 January 2013Excellent! :yahoo: Congratulations! I'm SO glad it is all working out for you, after all the problems, heartache and expense you have been through! And also glad we…
beeros05, 29 January 2013:D :D :D I have placed bass traps on all corners plus ceiling/wall corners. I have also placed broadband absorbers. It is a bit "damped". I placed some panels but i had…

beeros05, 30 January 2013These are custom order Stuart. You can order them from any company with aluminum profiles for doors/windows etc The most important is to order a profile with…
beeros05, 31 January 2013Sound Reduction Measurements OK, so I called a drummer friend of mine, heavy hitter, in order to do some measurements. I used the SPL iPhone app. Here are the results…
Soundman2020, 31 January 2013Great! iPhone apps are not very accurate, since the mic and circuitry was never meat to be used for acoustic measurement, and most likely don't cover the necessary part…
Soundman2020, 1 February 2013OK, so assuming your buddy was playing typically, and your snare hits 110, then lets' call his level 110 (conservatively). So, 110 inside, 43 outside.... That's 67 dB of…
beeros05, 1 February 2013Why are iPhone apps inaccurate? Because they are "apps" or because of the built in mic? There are apps that you can use external mic. So maybe I should find a way to…
Soundman2020, 1 February 2013The mic is not an omni with flat response from 20 Hz up to 8kHz, it cannot handle very loud sounds without clipping, and the pre-amp is not meant for acoustic work…

Soundman2020, 28 November 2015And what I perceive is that you are nothing but a lousy spammer, who did not bother reading even one single word of this thread! Therefore you will be banned and blocked…
Soundman2020, 4 January 2016Very nice Spiros! Finally, a YouTube video about isolating a room, that is correct and truthful about the acoustics. There's a couple of problems with the soundtrack on…

beeros05, 4 January 2016Thanx !!! :) :) :) Stuart these are sound effects… I have synced some effects as noises examples. @5.33 it is an example of loud music (from our neighbour) @5.43 its…
Soundman2020, 26 February 2019It would be better to ask that in your own thread, probably... But the simple answer is: it depends what aspect you are trying to look at! For example, if you want a…
