Denis these videos have helped as a hobbyists to putting together a beautiful sounding mixed use room of movies and music. The sound stage and separation and height iv been able to create in a room with 8 foot ceilings..wow. Thank you.
Let me say thank you again Dennis. Your videos/academy/forum have saved me so much money and frustration. I thought I wanted to add diffuser to my room. No doubt they look really cool. Thanks to you I learned that they would only add to my woes. So fortunate I found your company.
"They look cool" is a popular response I receive when I ask people why they put diffusers here or there. They "look" even cooler when the technology is applied in the proper position and work correctly. Funny thing happens. People forget about "cool look" and focus more on sound quality which is the technologies objective. Humans are a funny lot.
Focus on the absorption requirements of the room first. You must have many acoustic variables satisfied prior to introducing diffusion. The next variable is distamce from diffuser along with usage.
@@AcousticFields I don’t have a room at the moment, been living as an underemployed refugee in my mom’s basement, with most of my speakers in storage. I have about 6, 24”x24”x3” polyurethane foam pieces I scrounged from a recycle bin. Which I may double up for 6” thickness to get broader spectrum absorption, and across less surface area to not over treat my next space. I’m really thinking of building a listening room/living room hybrid, going all in from the get go with new home construction or renovation. I know your charcoal is much better, than the polyurethane but my thoughts aren’t even about using what I have, but how to engineer the optimal space. I find allot of joy in the hobby of design, and in the science of sound, and geometry, and the optimal tuning of things. I’m more entranced by learning about sound than by actually listening to music, which I rarely do these days. Most of my listening is podcasts and youtube, which is probably not what most think of listening to when they think of an audiophile. So I ask from acoustic curiosity rather than for immediate application in my non existent listening space. I’m very interested in understanding the logical reasoning of prime numbers and the frequencies chosen for the wells. I’ve really learned allot about the low end pressure component of acoustics from your recent videos and it’s truly expanded my understanding from where it was even a few weeks ago. So thanks for that. Anyway, feel free to go at your own leisure with your content, but if you put out some more stuff on the well tuning I’d enjoy that. Thanks :)
Thank you Denis. We are learning so much with you. Is it possible to have videos with physical examples or schematics. It will be easier for us to understand each point if you share more pictures
I really like the blackboard/chalk. It has a far more human feel to it than computerized lettering/graphics. I MUST say, in spite of the pun, that this teaching is really resonating with me, stuff I've considered for decades.
I remember many years ago Acoustic Fields had solid wood block diffusers that would cover the high frequencies above the standard Quadratic Diffusers you offer? Can people still purchase those from your company?
@@AcousticFields Are we talking about the same product? I was able to find the actual product and it's the MDW (Mini Diffuser Wood) and it was marketed to treat Flutter echo. Due to the product appearing to be thinner, wells/troughs are also thin and shallow, I would assume the frequency range would be narrower and higher. is that assumption correct? ruclips.net/video/-XcUNvL7-qE/видео.html
Hi sir I don't understand how the well width would be half the wavelength and the same time remain constant across the pannel what's the formula to determine the well width??
But the modulus n formula deremintes the depth proportion between each wells, when it comes I've seen here and something like lambda over 2 which is the wavelength, but what wavelength are we talking the one correlated with the design frequency (like 1000hz) or the one that results with specific well depth (like 3300hz or 880hz...)

Thank you so much for your videos. This is very interesting and useful for students who study disciplines related to sound!
Glad it was helpful!
That’s cool, I’d love to see more content about the prime numbers, bandwidth, and the fundamental frequency chosen.

The production costs for this process would not be cost effective in a video format.

Blackboard is easier to light for video than a white board.
Very true yet the best option is always a proper volume room then some absorption and Diffusing to fix it a bit.
Proper room volume along with proper type, amount, and placement of low frequency treatment.
I remember many years ago Acoustic Fields had solid wood block diffusers that would cover the high frequencies above the standard Quadratic Diffusers you offer? Can people still purchase those from your company?
You are describing a two dimensional diffuser. We do not sell those. You can achieve the same results with one dimensional placement.

The mini wood diffuser covers a higher frequency range. It is designed to add "sparkle" and "air" to high frequencies.
@@AcousticFields That's what I thought. Do you still offer them? They aren't on the Shop section on your website.

Reserach the modulus n formula. You will find your answer there.

👌👍
Thank you for your continual support and following.
Another good video Thanks 👍
Glad you enjoyed it
