Truth be told, room flutter and instantaneous sound reverberations can occur at many different points in a room, and ceiling soundproofing most likely will not be the "cure-all" that will fix this problem. But before we get into that, it's important to take a closer look at the (somewhat interpretational) differences in how acoustics are defined as either good or bad for recording purposes. Afterall, you'll need to evaluate what it is exactly you want to change acoustically in your recording area, whether that's through ceiling soundproofing or by some other means. (Apologies if some of this material was covered in other articles, but some of these points need to be reiterated.)
and Ceiling Soundproofing Options |
Home studio recording is usually done in one room, so it's a given that the room you'll be using should be tailored to the needs of recording if you want the reproduced audio to be flattering. So what does make a good sounding room? In general, the ideal recording room is one that has a clean and even sounding acoustical ambience. Ambience is more or less a modest reverb inside the room that enhances sound throughout the various frequencies that are produced by the instrument or vocalist. Think of an instrument as the paintbrush, and the room as the painter's canvas. You can have the most beautiful pallette of colors at your fingertips, but if you're painting those colors onto a weathered and wrinkled canvas, the end product will have a lot less life and vibrance in it than it would if the canvas were in pristine condition. Everything goes hand in hand..
So just to be clear, the ideal multi-purpose room is one that maintains relative neutrality; there shouldn't be a lot of depth to the sound reverberations, and at the opposite end of the spectrum, the room shouldn't be totally wallpapered with ceiling soundproofing or wall soundproofing materials so that it's completely deadened and unnatural sounding. What you want is balance. And remember, we're talking about a multi-purpose recording room. There may be times that you want to record a song with completely "organic" elements like natural delay, or reverb. It's in those instances where professional recording studios have the upper hand because of the amount of rooms they usually have to spare. And since most home studios will never have an echo chamber or mini concert hall with marble walls, you'll just have to rent out another space for those kinds of projects.
Now moving right along, let's define perhaps the most frequent acoustical problem for home studios- room "flutter." The term sounds more self-explanatory than it actually is, and it'd probably be best to just leave it at that. But since we just love making simple things sound way more complicated than they are, we'll define flutter as the end product of sound traveling around (and reacting within) a room's angularity. You learned in your high school physics class that every action has a reaction. Well, the same goes here obviously. There's most definitely a more accurate way of describing the technicalities of acoustical reactions, but it'd be a waste of time going into that since the root of acoustical problems virtually have no bounds and therefore a solution for one person may bring about completely different results for another person. The bottom line is that you may have to go through some trial and error before you find what works for your room.
Ceiling soundproofing can however be utilized (along with several other soundproofing options) in order to reduce flutter. Where ceiling soundproofing comes especially in handy here is when you have arched (or "V") ceilings. Sound will bounce off these parallel angles quite a bit, and effective ceiling soundproofing can subdue that considerably.
Your ultimate goal isn't to deaden your room, or even dampen it really, but simply to control the sound being produced within it. What you should try to aim for is a room that will accurately portray your instrument or voice so that when it's printed to tape or sent to your DAW (digital audio workstation,) you'll be hearing just the instrument or voice, and not a lot of excess baggage produced by the room's acoustics.
And that basically sums up creative soundproofing in general, whether it's ceiling soundproofing or wall and window soundproofing.
