Acoustical Treatment AutoCalc
This calculator automatically suggests the amounts of our line of AcoustIQ absorbants, bass traps and diffusers needed to lift your room to the next acoustical level!
Although the best approach is always to actually measure you room on-site and carefully adding treatment to approach the desired RT, normally optimal in the 0,4-0,6 level for a home cinema room. RT is short for Reverberation Time and basically depicts how much reflection is left within the room. In a studio environment, you´d want a very low RT, typically around 0,1-0,2. However, in a home cinema, you would want to keep some of the acoustical reflections "alive" for a bit longer, so that the perceived size of the room is better maintained.
Our approach when AutoCalcing your room is simply to keep the absorbers at a minimum around where you´re seated, while adding quite a lot of diffusion which is basically impossible to overdo. Using filtered and/or hybrid absorbption such as our Dfusors or filtered BassTraps, you also reduce the risk of overdampening the far more sensitive mid- and upper frequencies.
Please use this AutoCalc as a basis. After you receive the panels, our recommendation is that you install the purchased acoustical elements stepwise, measuring your RT-level using for example a miniDSP UMIK-1 calibrated mic (can be purchased directly at minidsp.com or through us) and the freeware REW-software. Please remember that a number of factors also also apply; type and amount of furniture and even the number of people seated.
In short, when acoustically treating your room, the goal is to ease the acoustical reflections - without killing the feel of space and roominess at the same time. If the sound waves are allowed to bounce back and forth, up and down, side to side - too much - the result is less clarity. However, placing the room full of absorbers and bass traps is certainly also quite risky as it potentially removes the acoustical feel of space at the same time, giving you the perceivance of being placed inside a smaller room than actually is the case. This poses a potential big problem for (home) cinema rooms that acoustically speaking is considered quite small to begin with.
At DreamScreen, we have carefully made out a line of acoustical treatment panels that combine absorption, bass-trapping and diffusion very effectively while still maintaining the acoustical feel of space; AcoustIQ.
The front absorbants, preferably placed all around the screen, at sidewalls and ceiling, effectively treats the first reflection from the speaker setup, reducing the energy of the remaining sound waves throughout the room.
For placement above your seating position, we have carefully designed Skyline diffusers based on well established QRD principles that have been tuned in to be effective at even very short distances.
The hybrid Dfusor panels, meant for placement directly to the left and right of the listening position, effectively combines both diffusion and absorption in the same panel.
Although diffusers are not as effective as absorbers, they do a lot of work nonetheless, but even more important; they do not steal the same amount of acoustical energy and thus potentially damaging the feeling of space like absorbers too close to where you are seated may do.
Bass traps are a challenge though. The back wall of your room is actually a primary reflective surface and although you use an acoustical transparent screen, preferably ours, and absorbers behind and around that screen in front, it is definitely an advantage to dampen these primary reflective sound waves hitting your back wall as well. However, since you are often seated quite close to the back of the room you do not want the regular bass traps that also kills the higher hertz levels. Our bass traps are equipped with a specially designed filter that cuts the absorption down to a minimum once 500Hz is passed. As such, you will not "muffle" the sound although you are effectively treating the lower frequencies of your first reflections close to where you are listening.
