Hi, next september my friends and I (all at music college) are moving into a house which has 3 rooms in the basement which we have been told we can do whatever we want with. I already do a fair bit of bedroom recording, mostly of drums (I'm a drummer) and we thought it would be cool to turn the rooms into a studio. There are a few potential problems with the basement though.
Firstly, The ceilings are very low (probably about 7 feet, I don't have exact measurements). One of the rooms has a fire place shaped hole in the back wall. all three rooms are pretty big apart from their height, again I couldn't take measurements but if they would be helpful I can see if I can get some.
the second problem is that there are small grills between each room, I guess some kind of ventilation (there are no pipes or anything they are literally just holes between the rooms). I thought these could be made useful for running cables between the rooms without having the doors wedged open, but I assume I would need to cover them in some kind of rock wool? The floor at the moment is just some kind of concrete or cement or something, but we plan to cover it with rugs and old carpet. The walls are just painted bricks, as is the ceiling (but with areas of hardboard and a lot of pipes and things). Do we need to cover the ceiling pipes with something? and is it worth buying proper acoustic foam pads for the walls or can we just put up wall hangings?
we are all students so budget is pretty limited, but we're prepared to spend enough to make it useable.
The final problem is damp. We're based in Manchester, UK which as you may know is a pretty wet place. The landlord said that it had only flooded once in the last 10 years, so we're not too worried about that as long as we keep an eye on the weather forecast, but the floor does look kind of damp. There are currently various bits of building materials being stored in there and they don't seem to be too damp, but I was worried about keeping nice instruments and equipment down there. We are going to get some kind of humidity reader and dehumidifier down there, but does anybody know what kind of humidity levels are safe for drums/guitars/studio equipment.
any help you could give would be very much appreciated as I know very little about acoustics.
 
Hi Matt,

What's your budget?

If you need to sound-proof, you will need mass and seal. Rock wool doesn't help.

It will require considerable construction to make studio rooms that will enable you to rehearse, record, and/or mix without bothering neighbors. Yes, please post the dimensions and some photos too so that we can give educated answers to your questions.

Humidity is a real concern and should be fixed at the source - i.e.; repair the basement walls/floor. ;)

Cheers,
John
 
Hi, next september my friends and I (all at music college) are moving into a house which has 3 rooms in the basement ....

Next September? Can you work on it now? Or do you have access now?

...which we have been told we can do whatever we want with

Thats good. Unfortunately, what one wants and what the building inspection department says is ok are two different animals. :D Especially if this a habitable space. I don't know how the permitting process works in your area, but most contemporary urban residential structures are usually within the jurisdiction of a Building Inspection Department. Reason I mention this is "soundproofing" implys significant construction which "may" conflict with common local regulations. And to get permits, "usually", for un-common construction, one usually is required to submit a set of plans showing what you are planning on building. However, at this point I was just pointing this out, as John mentioned "soundproofing". Although..you didn't say anything about it. Frankly, since you are asking questions in regards to 3 different rooms, this suggests you are planning on using one as a control room and the others as recording spaces. If so, then yes..you will need to isolate the various spaces from each other by virtue of "bleed" and what's known as "transmission loss" through building assemblies. Not to mention "flanking paths"...ie..structural transmission and or air pathways between the spaces. Hence mass and seals like John said.

Firstly, The ceilings are very low (probably about 7 feet, I don't have exact measurements). One of the rooms has a fire place shaped hole in the back wall. all three rooms are pretty big apart from their height, again I couldn't take measurements but if they would be helpful I can see if I can get some.

Absolutely. Like I said, IF you have access, and or IF you can start building soon, it may take from now till September to actually complete a project like this. Reason is, like I said, you may have to submit plans, depending on the scale of your intent. And that usually takes time, first for the design process, and then for the submittal process. Of course, even once approved, soundproofing construction is not easy nor intuitive, and will take time as well.



we are all students so budget is pretty limited, but we're prepared to spend enough to make it useable.

That's the reason John mentioned BUDGET first. Without a significant budget, all else is moot...sorry to say, but it's the truth. At least in regards to "soundproofing". Even correct "treatment" is not without significant cost as well.

the second problem is that there are small grills between each room, I guess some kind of ventilation (there are no pipes or anything they are literally just holes between the rooms). I thought these could be made useful for running cables between the rooms without having the doors wedged open, but I assume I would need to cover them in some kind of rock wool?

This all falls back on "soundproofing" and whether or not you can afford it. Look, the whole purpose of having a separate control room from the recording spaces is so the engineer can "hear" over the monitors what the mics are picking up in the other rooms. IF, sound bleeds through the walls etc then what the engineer hears is a combination and can NOT make accurate "judgements", as the sound coming through the walls will alter his perception of what he is hearing from the monitors. That is why soundproofing is important. Not to mention driving neighbors crazy, picking up environmental noise while recording notwithstanding:D

The floor at the moment is just some kind of concrete or cement or something, but we plan to cover it with rugs and old carpet. The walls are just painted bricks, as is the ceiling (but with areas of hardboard and a lot of pipes and things). Do we need to cover the ceiling pipes with something? and is it worth buying proper acoustic foam pads for the walls or can we just put up wall hangings?

The ceiling is brick?:eek: hmm, never seen that before. What was this..a dungeon?:D Well, at this point, without knowing a whole bunch of details it wouldn't be wise to speculate on solutions, as we don't even know the real problems yet.:facepalm: That doesn't mean we arn't willing to help. It just means we need a TON of info before we can really help you. As to pipes etc, no, usually it's not really required to cover them unless your soundproofing criteria requires it, as pipes can be a flanking path in some respects. Especially large ones. Again, we don't know at this point.

The final problem is damp. We're based in Manchester, UK which as you may know is a pretty wet place. The landlord said that it had only flooded once in the last 10 years, so we're not too worried about that as long as we keep an eye on the weather forecast, but the floor does look kind of damp.

I'd submit that's a red flag. How damp is the question. And where it's coming from? The walls? Or weeping up through the concrete floor. This could be an easy fix or it could cause a complete abandonment of the project. It all depends on..you got it...KNOWLEDGE. Frankly, if it were me I'd be all over this one ..in detail. This is where LOOK LOOK LOOK comes in. A thorough examination would be prudent as it could come back to bite you later should you ignore it.

I have a question though. How is this space HEATED?

I'll be back.
 
Like you said, we're not going to be able to afford huge construction projects and full scale sound proofing. What I was really trying to ask I suppose is where we can make cheap improvements on what we have, rather than aiming unrealistically high. For instance, would sticking up small bits of rock wool or something similar over the grills I mentioned actually make much of a difference? We have the lease from the beginning of july, before then we can arrange further viewings but I doubt we'll be able to start any work (although the current occupiers don't seem to be using the space at all so it might be worth checking). I'll post more details about dimensions and such as soon as I can.
I know that this won't end up being an ideal space with fully isolated control room and tracking room and amazing acoustics etc, but I'm hoping it can be an improvement on what I have at the moment which is just my computer and monitors etc in my bedroom along with drum kit and any other instruments being recorded in the same (completely untreated other than a blanket over the drums when they aren't being played) room. The basement is only under our own house and we are all musicians and happy to put up with the noise,
 
My thoughts.

If it's only you guys living in the house and noise is not an issue, then don't even concern yourself with isolation or sound-proofing or whatever you want to call it. Think in terms of acoustic treatment; getting the space to sound good. Ideally you want a nice sounding recording room and an awesome sounding mixing room. They don't necessarily have to be separate rooms. On a budget, you can make big compromises in construction with a little bit of creativity and a lot of DIY and not make big compromises in results.

Now for that red flag Chronicle mentioned.

You do know electricity and water don't mix, right?? This is a HUGE RED FLAG to me.

thanks guys. regarding the damp issue, we'll have access to the house from the beginning of july but won't actually need to use it for recording and practice etc until september, so my plan was to start getting dehumidifiers in there along with a humidity reader just to see what the situation is actually like (at the moment I'm just guessing) and get some real numbers to think about. do any of you know what humidity level (as a percentage) is "too high" to keep this kind of gear in?
"On a budget, you can make big compromises in construction with a little bit of creativity and a lot of DIY and not make big compromises in results."
could you give me some ideas of what kind of things I can be doing? I'll get measurements and pictures to you as soon as I can
thanks
 
'hasn't flood in 10 years' doesn't mean squat. The basement in my house hadn't flooded in 15 years. Then we had a lot of rain - enough for the river that's 100 yards away to flood the road half a mile away. The ground saturated everywhere in the valley. Water was coming up through the floor, through the walls .... 8" deep at one point.
Only thing I lost was a tub of Xmas decorations that got knocked over and got wet (unknowingly until opened months later - YUK!), but furnace needed new burner and servicing.
I would not even consider putting equipment down there permanently. From your description its going to take a ton of acoustic treatment to sound half-decent.
