These 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 circumferential sealing mechanism. There are 2 types of this mechanism. One is for security (and more expensive) and the other one is for thermal insulation and sound insulation at the same time. Mine is the second one. The triplex laminated glasses were ordered by the aluminum company after I gave them my specs.Nice! Where do you get those doors? Very neat.
Just hold it out at arms length, chest height, pointed upwards at an angle. Measurements are normally taken 1m from the wall, door, window, instrument, speaker, mouth. etc. - Stuart -I had no idea how to use it or calibrate it properly
I am a heavy hitter, but not for 2 hours...my average measurement where maximum 100db My snare reaches 110db But these numbers are average. I am around 90+ dbHow loud was it inside the room while your friend was playing? It would be very useful to know that, to get a rough idea of how much isolation you are getting.
Why 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 connect a mic with my iPhone, what type of mic should i use?Even assuming that the iPhone app is very inaccurate, and off by 10 dB, 57 dB is still really, really good, and something to be proud of.
Yeap, sth like this... I have noticed since I installed the doors that the bass drums sound MUCH better! Why is that happening?In fact, you have achieved the "holy grail" of home studio building: effectively isolating a drum kit, in a small room, and it still sounds good inside!
Good idea, and thats because this "case study" is not only "what to do" but also "what NOT to do" :P You cant see me, but Im laughing :yahoo: I recall one year ago these days...I was so unhappy and disappointed and now I can play 24/7 !!! And here comes the BEST part... I bought a Zoom R16 Recorder / USB Interface and a used MacBook with Logic Pro and a set of budget mics. The interface is pretty good, value for money product, but still doesnt have very good preamps. The mics are also "budget" I have started recording and mixing 2 months now, I am very newbie. I called some friends, sound engineers, to hear some mixings of mine. FLAT, no EQ, compressions etc. They couldnt believe what they were hearing! One of them told me to use my room for his drum recordings :shock: When I find a job and get some money I'll buy better mics and a MOTU Interface...I'm going to ask John to make this thread into a "sticky", as it is a shining example of the correct way to build a drum room.
The 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 either. It is a very cheap mic on a very cheap pre-amp.Why are iPhone apps inaccurate? Because they are "apps" or because of the built in mic?
Well, you could do that, yes, with an external mic and pre-amp..... but you'd spend more money than by just buying a meter on e-bay or Amazon.com! A decent meter costs around US$ 75 - 100 (don't go for the ultra-cheap US$ 25 Chinese junk), and that is NEW! You can often find used ones for about US$ 50 or so.There are apps that you can use external mic. So maybe I should find a way to connect a mic with my iPhone, what type of mic should i use?
I'm not 100% sure, and just guessing here mainly, but I suspect that it's because the room is now air-tight with the doors closed, so that is keeping the very low frequency pressure in: so the room is "pumping" now, with the low frequency over-pressure from each kick hit, instead of that over-pressure being able to "leak" out through the doors. Just a guess... Do you have both heads on the kick? Does the front head have a hole in it, for the mic? In general, I find that in small rooms, drums sound better with the front head removed, or at least with a decent sized hole for mic'ing. Also, how are you mic'ing the kick? It depends on the mic and the sound you are looking for, but I find that a good place for the mic is about 2" away from the back head, a bit below the spot where beater hits the head, and pointing right at that spot. That's where I normally start with mic'ing the kick, then move it around a bit to see if I can improve on that. Mic'ing drums is part science, part art.... Everyone has their own technique!I have noticed since I installed the doors that the bass drums sound MUCH better! Why is that happening?
Is that what you used to record the You-Tube track? If so, that's not too bad at all. Sounds quite decent, actually. - Stuart -I bought a Zoom R16 Recorder / USB Interface and a used MacBook with Logic Pro and a set of budget mics.

Read the thread from the start: it's all explained in the posts. - Stuart -You guys did a great job! But I'm just wondering: What is the purpose of this build? Do you need to isolate the room so that your drums can't be heard outside? Or are you trying to keep out some noise from the outside?
Congratulations!!!! :thu: :yahoo: :yahoo: :yahoo: A long hard road, but you finally got there! I'm glad we were able to help you out a bit along the way. This is actually one of my favorite threads!!!! - Stuart -
Thank you everybody, I am so grateful to ALL of you! The credits belong to you guys and the forum. Here are some more pictures Drumkit Mixer Front Mixer BackGood to see that you have such a great place to work in Beeros. You deserve the credit since you made all the right decisions. And now this thread may stand for a long time and be read by many, many others and you can teach them with your efforts. Good luck,
And 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 if you don't man up and prove your claims. In reality, this room is one of the best isolated studios on the entire forum, which is already full of many, many well-isolated rooms, all of which are vastly superior to what might be expected of a third-rate urban-planning outfit with no background in studio design. This room provides absolute isolation from the people in the surrounding areas (as you would know if you would have bothered to read the thread). Even those right outside cannot hear the bad at all. If you really did have this same problem in the past, and if an "urban planning" organization really did "satisfy" you, then please do go ahead and document that studio build in your own thread. We will be happy to critique it for you... 8) Finally, Beeros actually did "take assistance of some good planner", meaning all of us here on the forum who gave him solid, sound, precise acoustical advice, which he then used to build this excellent place... as you would know if you bothered to read the thread! And we already did "sort out this problem completely" ... as you would know if you bothered to read the thread! Now either provide the proof that substantiate your claims, or shut up. And either way, stop harassing people like Beeros who have done an outstanding job building their rooms, and stop hijacking the threads of other people with your inane "advice". - -Hi, what I perceive and judge that this room is quite small and difficult to accommodate so many musical equipments inside it...and so far you want perfect isolation and non-reverberation so that a good sound quality can be produced without disturbing the people in surrounding area...as same sort of problem I faced in past and I took help from [SPAM LINK DELETED BY MODERATOR] who made me satisfied and they have very talented and laborious staff who can do anything...however you can take assistance of some good planner or constructor who can sort out this problem completely....
