We offer a series of product videos designed to provide information on the full line of GIK Acoustics products. We've also created a series of helpful Educational Videos which demystify the science of room acoustics. At GIK Acoustics, we offer quality, Eco-friendly products and provide our customers with custom acoustical advice. We take a holistic approach in helping customers understand the acoustical issues in their space and then present a practical approach to addressing the issues.
The noisy background music here, combined with the presenters speech impediment makes it very difficult to understand what the hell he is trying to say.
The background music playing is very annoying, and competing with your voice. It takes away the quality of your video. Please take my comments as constructive, thank you.
The best advise is to place speakers close to the front wall as much as possible and the minimum for rear ported speakers is actually the diameter of the port. Everyone can mesure with REW and check it. That is why I like the example of flush mounted speakers in studios. The low frequency interference from the front wall is the worst effect in sound. “Audiophiles” did not understood this yet for some reason.
Interesting take to say "in smaller rooms, it is best to place speakers close to the wall and focus treatment around the monitors" I can see why...I thought more distance was generally better so I'd manage what I could.
Alright, im new to this so be gental. Im a bit confused and im lookibg for a bit of clarity. I have a pair of Kef Q350's, a Denon X1800H and will be adding a Rythmik 12 inch sub very soon. If I use the USB mic, this program and my laptop to get my room measurments to correct any issues what content am I playing for play back from my AVR in order to get said measurments? Am I missing something in this video?
I have 4 panels very similiar to one on the left near the window at 3:43 and I still get quite a lot of room sound when placed next to walls at early reflection points. The other day I got an idea, to put them instead of next to the wall as close to speakers as possible... the listening position feels a lot less verby now, which I like a lot more. But I'm wondering if I might have created some other problems with this solution... can anyone let me know if this is somehow wrong?
If the air gap between the side wall and the panel is more than 2x, theoretically, you may create dips in the absorption coefficient in certain frequencies. Porous absorber calculator by acousticmodeling shows this. But if it sounds good, than no worries, enjoy!
Thin panels reduce high end.. thicker deal with low. a 6" panel with a 2" gap that is sealed in the frame & mounted flush to the wall the will isolate the lower end making the best option for trapping low end. defusion behind you absorption in front & to the sides. you can defuse on the side also depending on the room! This is a summery from the last 3 years of interviews with studio designers & builders.
Much of the information here is spot on, with one big exception. The human ear is not sensitive to the type of diffusion when the diffuse sound is coming from behind the head (front and sides are different). So it doesn't matter if you're fussing about exact formulas. What matters is "visual irregularity" and that you don't cover more than 50% of a module or 30% of your entire back wall with diffusion for a control room. And in fact many types of back wall diffusors can create problematic hot spots. Source: Master acousticians and control room designers Philip Newell and Tom Hidley.
"The human ear is not sensitive to the type of diffusion when the diffuse sound is coming from behind" - there's no such a type of diffusion "coming from behind". The aim of diffusion is phase grating, and no matter where the diffusors are located in the areas of the first reflection points -- they can improve the acoustics of your room if they are properly designed. The rear wall is the most important for the midfrequency range as far as the rear wall receives the most of the energy from the front mounted speakers and the rear reflections can be a big problem if the wall is not properly treated.
Is it best to just get as many monster traps as you can afford and forget thinner panels (especially if you make music with heavy sub and kicks)? Or should you always mix them with 244 or 242? Might as well go full range no?
I want to measure all 5 ear level speakers, how do I get the Center and side surrounds? You just did the left and right front speakers? Should the receiver level be set at reference level? Should speaker levels in the AVR be set at 0.0? I need details!
