Dr. Lars-Johan Brännmark, Research Fellow and Chief Scientist at Dirac, has given a glimpse into what he believes will be the next generation of room correction. Spatial room correction is a concept that goes beyond correcting each speaker individually in the frequency and time domains. Instead, all speakers work together to correct each other, allowing the user to manipulate the spatial qualities of a system and overcome acoustical problems that are usually left unaddressed.

The quest for the “perfect” room all depends on your expectations, why you are listening (business or pleasure), what program you are listening to, and the condition of the ears you are listening through. This article and recently added YouTube discussion focuses on the topic of early reflections in small room acoustics and how to deal with them based on listening preferences and the accuracy of your loudspeakers. The portions of side walls responsible for first lateral reflections are specified as “optional areas: absorb, diffuse, reflect.” It is a decision to be made by the customer and/or the installer.

This is a question that for too long has been shrouded in mysticism as if there were some ephemeral magic that touched some systems and not others. But, the truth is this question can be approached objectively, and indeed that is what Dr. Floyd Toole has been doing with over a lifetime of scientific research. The results of his research is presented in a clear, concise third edition of his book 'Sound Reproduction,' which makes for an enlightening read for neophyte audio enthusiasts and long-time audiophiles alike.Mon, 11 Dec 2017 18:00:00 -0000 https://www.audioholics.com/room-acoustics/sound-reproductionRoom Acousticshttps://www.audioholics.com/room-acoustics/history-of-multi-sub-sfmThe problem with the small rooms we listen in is that they so often present us with offensive bass booms, and the bass is different at different seating locations. The traditional solutions for taming room resonances have relied on low-frequency absorption (a.k.a. bass traps), system layout, and manipulating room dimensions. In homes these may or may not be practical. So my team and I investigated alternative solutions, leading to multiple subwoofer strategies and a sophisticated DSP process called Sound Field Management (SFM). This article describes the evolution of these methods, that can replace or supplement bass traps in some situations.Mon, 21 Mar 2016 21:45:00 -0000 https://www.audioholics.com/room-acoustics/history-of-multi-sub-sfmRoom Acousticshttps://www.audioholics.com/room-acoustics/bass-the-physical-sensation-of-soundHave you ever watched a bombastic movie in a theater with a heavy-duty bass system and felt as battered as the film's hero afterward? Ever wondered how a kick drum sound could cause that 'chest punch' sensation? Did you know that at a low enough frequency, high-amplitude sound may even be able to breath for you? In this article we look at how bass is felt rather than heard, and, after reviewing some of the research that has been done in this area, we investigate the points at which low frequencies go beyond sound and become a tactile sensation in an experiment of our own with willing volunteers. We caution readers NOT to try these experiments at home.

But there are fundamental differences and objectives between the two and thus they should be handled differently accordingly. Small rooms are dominated by room modes at low frequencies which needs to be addressed either with passive room treatments or a multi-subwoofer approach. It has been shown that early reflections can be beneficial for perceiving ambiance and spatial cues in the music. This article and accompanying YouTube video discusses these topics in more depth and gives recommendations for consideration of sound reproduction in small room acoustics.Thu, 17 Sep 2015 04:00:00 -0000 https://www.audioholics.com/room-acoustics/small-room-acousticsRoom Acousticshttps://www.audioholics.com/room-acoustics/early-reflections-in-home-theaters-a-different-perspectiveEarly reflections may or may not be major problems in home theaters. Addressing them through the use of heavy absorption should be pursued with caution and recent research indicates it may not be needed at all for lateral reflections. I believe the issue of early reflections and their relative merits (or lack thereof) in any home theater should never be ignored.

Some do it with cables, while others employ more aggressive measures like bass and treble controls. As time progressed, our technologies advanced and we've come up with more sophisticated tone controls such as Graphic and Parametric Equalizers to offer more finely tuned adjustments. A/V receiver manufacturers and companies such as Audyssey and Dirac have also developed their own EQ systems that measure your room response with a microphone to further tune your system. But are these auto setup and EQ systems to be trusted? Are they really useful in helping setup and fine tune your home theater system?

One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale. Being aware of the relationships inherent in this scale is important for a variety of reasons, which will hopefully become clear by the time you reach the end of this article. We also discuss how the human hear perceives double loudness differently depending on frequency so +6dB increase in SPL may not seem like such a big deal at 1kHz but at 20-30Hz it certainly is.

If you are a theater enthusiast and want your system to sound better, don’t throw money at the equipment, put it into an HAA certified professional. The same goes if you are a two-channel stereo audiophile. Audiophiles always seem ready to purchase better and better equipment to perfect their sound system, which I am not trying to discourage, but they tend to disregard the proper room setup and calibration. Whatever place you take in this ever-changing audio world the one thing that stays the same is the physics of acoustics and HAA is the avenue for optimizing small rooms.

Indeed, most people opt for expensive, top of the range sound systems in an attempt to reach the best-possible sound quality. But they often ignore one essential thing: the acoustics of the listening room itself. As a sound system is used in an enclosed space ‘a listening room’, the acoustical conditions of that room will inevitably take control over the sound quality.

You love audio, are passionate about your system and are always searching for a better experience, a more accurate response. You’ve heard the term “room correction”. You’ve heard speakers in various rooms, you are aware of acoustical treatments and active room correction systems (ARC). You know that your dedicated audio system is not in a purpose built room. You would like to make the room as “correct” as possible; however you have no clear idea what approach is best for your room. This article explores the 20 questions you should ask yourself towards building a great room along with feedback from leading industry experts within their own respected disciplines on this topic.Sun, 09 Dec 2007 00:00:00 -0000 https://www.audioholics.com/room-acoustics/twenty-questions-toward-a-correct-roomRoom Acousticshttps://www.audioholics.com/room-acoustics/building-great-bass-response-in-your-home-theaterIf you are searching for the utmost listening experience in your room with your system it is time you consider how your space is constructed. It is the purpose of this article to show you how the construction relates to your audio experience. There is an inverse relation between sound isolation (STC) and sound absorption (NRC). The greater the isolation of a surface the more sound energy is going to remain in that space. This applies directly below 200 Hz where the resonance of room modes is a primary factor of your systems character. It becomes compounded when you add multiple sound sources with low frequency information…you got it, your room.Mon, 21 May 2007 02:47:22 -0000 https://www.audioholics.com/room-acoustics/building-great-bass-response-in-your-home-theaterRoom Acousticshttps://www.audioholics.com/room-acoustics/better-sound-through-active-room-correction-a-primer-to-audyssey-multeq-proAudyssey's Sound Equalizer is the company's first branded, flagship statement product.

Or perhaps they'll report that stereo imaging is poor, most likely due to early reflections off the side walls and ceilings. Indeed, everyone "knows" that to test the acoustics of a room you simply walk around and clap your hands while listening for reverb and echoes. But to my way of thinking a far more important problem occurs at low frequencies, and you'll never hear that with hand claps.

Truth is there are today microphones that can, with ease, outperform the human ear. Where the ear may, however, lay claim to the ultimate mic award is when it's considered in combination with the post-processor to which it is hard wired, namely, the human brain.

We are often asked questions like: "What can I do to this wall to stop the sound going through to the bedroom on the other side?" It's almost incomprehensible to people that the wall may not be (and probably isn't) the only part that is leaking sound to that bedroom. The other parts might well be the floor, the ceiling joists and other shared walls. You could make changes and increase the STC (Sound Transmission Coefficient) dramatically for that wall, but the result might be marginal because the majority of the sound is getting through elsewhere.Sun, 27 Mar 2005 00:00:00 -0000 https://www.audioholics.com/room-acoustics/a-guide-to-sound-isolation-and-noise-controlRoom Acousticshttps://www.audioholics.com/room-acoustics/room-acoustics-isolation-noise-controlOur first three courses in the CEDIA Seminars series covered proper system calibration after installation and set-up was complete, followed by two complementary courses on room acoustics.

This minimum five hour job was a step-by-laborious-step of set-up and reconfirmation of settings done months before. Inevitably, recalibration accompanied by more fine-turning was always required to make each channel of the Norris Theater system perform optimally.

There are so many facets that go into the listening room, and the most important is the desires of the client. I have a pretty good idea of what my perfect listening room would be like, and I can almost guarantee that it would not the same for many clients. Most people are surprised by my answer.
