Floyd Toole has become a figure not entirely unlike PWK: he represents a knowledge base in sound reproduction and identification of relevant measurements that correspond to listener preferences. This stands in contrast to what I consider to be a general wasteland and land of confusion and folklore memes filled with pseudo-science and belief systems not backed up by fact. His newly updated and very recently released 3rd edition of his notable book: Sound Reproduction--The Acoustics and Psychoacoustics of Loudspeakers and Rooms has been largely rewritten and somewhat refocused.
Read times. Loudspeakers, Rooms, and Subwoofers - Audiophile Articles. Together again for the first time, eleven white papers written by Floyd E. Toole, Ph. Due to the fluid nature of the web, previous links to these papers no longer worked. Though still available on the Harman web site, these papers are hard to find so I consolidated them in one location. Excellent reading for beginners and seasoned audiophiles.

Toole, Harman International Industries, Inc. Designing a dedicated listening room? This white paper will get you started with formulas to determine the perfect room including sections on room proportions, background noise, reverberation time, and control of early reflections.
Floyd E. Controlling reflections can optimize imaging and spatial effects. Multichannel audio should be shared, so we try to get good bass at several locations. Acoustical knowledge is essential, but EQ can help.
This idea has potential where there is not a single listening location, but rather a listening area. Standing waves within the room cause large frequency-response variations at the listening locations. Furthermore, the frequency response changes significantly from one listening location to another; therefore the system cannot be equalized effectively.
However, through the use of multiple subwoofers the seat-to-seat variation in the frequency response can be reduced significantly, allowing subsequent equalization to be more effective. Getting good sound in a room. How is it done? The better the stereophonic reproduction system, the less trouble we have with room acoustics. The result is intriguing. It turns out that some of our common practices are less than optimum, and some popularly held notions might need to be revised.
Part 2 of "Maximizing Loudspeaker Performance in Rooms" has detailed information on how to interpret the graphs. The calculator uses Microsoft Excel or compatable spreadsheet for the calculations. Member Posts: Thanks very much! Those are great articles. Being that I'm a multichannel fan and am interested in trying multiple subwoofers in a small rectangular room, I'm appreciative of these articles. Thanks a lot! Cheers, Robin.
Apparently, it isn't available on the Harman website anymore, but if you PM me with your e-mail address, I can send you a copy. Also, Toole is retired, from what I understand. Loved this part. Short and sweet. I nominate this thread for "sticky" status. Rob, please consider making this a sticky. This has to become a sticky.
So much excellent info, and completely debunks a lot of the crap out there in the internet, such as this. The theory seems marginally okay, but the implementation? Egg crates? An example of what NOT to do! Thanks for posting these Wayne! I only wish I knew they were here earlier.
This should be a sticky. Everyone on this forum should read Floyd Toole's book. It is written in an accessible manner with minimum of math.
It is the best 'if you are going to only read one book on acoustics make it this one' book there is. Thanks again youngho, I added the papers to the list. I just added two more white papers by Floyd Toole to the top of the list. The paper describes the steps taken to build a new listening laboratory. The techniques and formulas in the article could be used to design the perfect dedicated audio room and include sections on room proportions, background noise, reverberation time, and control of early reflections.

A note from Floyd Toole: The purpose of this site is to provide supplemental information and different approaches to accessing the information in the book. The first topics relate to designing, constructing, equipping and calibrating stereo listening rooms and multichannel home theaters. In the future other topics will be addressed.

Floyd E. It is more than just an introduction to sound reproduction and sound quality; it is a comprehensive explanation of all of the components that add up to sound quality, and how that quality can be good or go wrong. The recently released 3rd edition is a major re-ordering and rewrite that is updated with much of the latest advances in research and technology on the subjects that are covered. The subtitle, "the Acoustics and Psychoacoustics of Loudspeakers and Rooms," touches on the chief components that determine the quality of the sound reproduction.

The physical measures by which acousticians evaluate the performance of rooms have evolved in large performance spaces—concert halls. They rely on assumptions that become progressively less valid as spaces get smaller and more acoustically absorptive. In listening rooms the loudspeakers and the rooms interact differently below and above a transition region around Hz, similar to the Schroeder frequency in large rooms. Save to Library. Create Alert.
- Если служба безопасности обнаружит затянувшуюся надолго работу ТРАНСТЕКСТА, перед нами возникнет целый ряд новых проблем. Я хочу уничтожить все следы Цифровой крепости до того, как мы откроем двери. Сьюзан неохотно кивнула. План неплохой. Когда служба безопасности извлечет Хейла из подсобного помещения и обвинит в убийстве Чатрукьяна, он скорее всего попытается шантажировать их обнародованием информации о Цифровой крепости.
Танкадо - мастер высокого класса, он никогда не оставил бы висячие строки, тем более в таком количестве. Эти висячие строки, или сироты, обозначают лишние строки программы, никак не связанные с ее функцией.

Этот узел представлял собой звуконепроницаемую уединенную камеру, расположенную неподалеку от главного зала. Двухдюймовое искривленное стекло односторонней видимости открывало перед криптографами панораму зала, не позволяя увидеть камеру снаружи.
Слова коммандера словно обожгли Сьюзан. - Дэвид в Испании? - Она не могла поверить услышанному. - Вы отправили его в Испанию? - В ее голосе послышались сердитые нотки.
Она пожала плечами: - Быть может, Стратмору не хотелось задерживаться здесь вчера вечером для подготовки отчета. Он же знал, что Фонтейн в отъезде, и решил уйти пораньше и отправиться на рыбалку. - Да будет тебе, Мидж. - Бринкерхофф посмотрел на нее осуждающе. - Дай парню передохнуть.
