Can't thank you enough for what you're doing Jesco. You probably know the tendency in audio-engineering circles to promote the "ear-only" approach, like if one does not need measurements and should only listen trying to find something pleasing. Hence the "every voice his own microphone" approach, which probably pleases manufacturers most :) With your information I really started feeling that I'm finally understanding where am I going in terms of building my own studio.
Great interview. I need to get this course. I'm literally at this point where I've built a bunch of absorber panels, but it looks like I need to apply this "systematic approach", so that I can ensure success in the outcome.
Nice interview. FYI: Materials are a lot cheaper in the USA. A bundle of twelve 4ft long x16in wide x 3.5in thick rockwool batts cost $60, available at any of the local home center. Oak wood boards 3/4 inch thick , 3.5 in wide, cost $12 per 4 ft board. I covered the entire panel frame with fabric so I could use pine furring strip boards that cost only $1 for a 4 ft long board. The fabric cost the most. I spend about $60 for very nice fabric to cover twelve 4ft long x16in wide panels. All the materials were available locally and fit in my Honda Accord, so I didn't have to pay (or wait) for delivery. PS: You should use a pneumatic staple/nail gun next time. I put panels at the first reflection points on the side and rear walls, smaller panels to cover the ceiling and desk reflection points. For bass traps, I put panels 3 deep set diagonally across the front corners, 2 deep across the rear corners, and triangular panels mounted where the ceiling meets the front and rear walls. You give the best acoustic advice on the web. (I have 2 Engineering Degrees plus a Masters Degree in Energy policy so I actually understand you.) Tks.
Hey Jesco, Loving these interviews, as always. In my previous studio, I used twenty 18cm deep panels, and they worked like a charm. Now, in a smaller room (2.49x3.12x2.45m) after selling my old panels, I'm thinking of going for those fabric stretch PVC profile systems for acoustic walls. But, I'm wondering if covering more surface area will really give me significantly better results than the panels. In a previous video you mentioned diminishing returns; what do you think? Your thoughts would be awesome! Thanks
Isn't it right that since echo time in LF not improved (500ms), that will still have huge impact on bass? Like, if frequency keep playing when other note already started - will it create additional disruptions in the said frequency response?
For me empty room is very hard to find seating position i prefer corner and middle absorber in place much easier to hear but i cant put sub in corner anymore so i use middle point.
Panels are 15cm thick and I have air gaps of ~20cm on the ceiling and the ones behind the speakers are in the corners so that's a fairly big gap. No gap on lateral panels indeed.
I hear early reflections in his voice quite heavily for a sweet spot (assuming he is sitting in the sweet spot). Very surprised with the prices, here in Brasil rockwool is insanely more expensive than wood.
Great video, Would these techniques translate to 15 channel home theater? I have an idea on where I should treat; ipsilateral and contralateral, corners for bass build up, and ceiling for for center speaker reflection. Curious if your ideas are only for studios.
Is there a reason you chose to build the panels without the diffuser faces that Jesco himself uses? What are the dimensions of your room please, as it looks like it could even be as small as the space I have to convert to a studio, although sadly, I think this is still ages away due to the list of other home improvements to do.
didnt catch which exactly rockwool was used? trying to find which one to take in europe but its so dificult as they dont need to measure gas flow resistivity anymore and it just syas ACCORDING TO EU STANDARTS.......which one to chose guys?
I went for 33Kg per cubic metre but it was difficult to find. The retailers don't seem to publish the gas flow figures but they do publish the weight and 33 is spot on. If its between 30 and 40 you should be fine. Hope this helps :-)
I used Rockmur Nu from Rockwool (each country has a different range it seems like that's the name here). It's the afr10 (meaning > 10 KPa · s/m2 air flow resistivity) product that is used for isolation of attics or that kind of thing. It doesn't have any paper backing or anything like that. I found the precise certification in a pdf on their website, they have to make them available for each product I think, you have to dig a bit but it's there.
Wouldn‘t it be better if he closed the gap to the wall of the front-corner traps? Also he didn‘t seem to have done anything on the back wall…. diffusors and combined diffusor-bass-traps?
This room is 4.3x2.41x2.48m, that translates to ~54m² of surface. 10 panels of 1.2x0.6m is 7.2m² so that's about 13% of coverage (but four of those aren't flat on the walls so not quite).
why do people pay hunderds Euro for a course, to know how to position yourself and put panels around your speaker and first reflections Points? Im not hating but what makes people pay that money?
Honestly, audio treatment information is pretty readily available at this point. Everything is out there to learn for free. People pay for these things bc they believe the course has magic information that isn't available anywhere else that will make all the difference in their setup. They are, of course, mistaken.
@@novinnovations4026@ novinnovations4026 I agree, his course is about building panels & placement which I think a lot of people have knowledge of placements but not building. The key is to make very thick panels and ensure you don't overkill your room so add some slats in front of the panel. I think adding slats would be the most difficult part because of the mathematical equation.
It's such a pleasure to watch the French and the German speaking in english somewhy ;)

Great interview, I just recently built my own absorbers and traps myself and I can relate to so much of this. Thank you both.

The total cost to make 24 rockwool panels, 4 ft long, 16 in wide, 3.5 in deep, cost less than $300 US dollars.
Thanks so much, again very informative and once again proves what's you can achieve when doing a few, but thought through, steps!

How thick are Paul’s panels and did he have any air gaps? It sounds like he didn’t as he said he screwed them directly to the walls. Thanks

Jesco, do you have anything to say about nearfield-subwoofer setups? If it would/could be beneficial etc
Is there a reason you chose to build the panels without the diffuser faces that Jesco himself uses? What are the dimensions of your room please, as it looks like it could even be as small as the space I have to convert to a studio, although sadly, I think this is still ages away due to the list of other home improvements to do.
Sorry if I missed it but, the graph axis at 43:50 are SPL, Frequency, and what? Decay time in ms? Thanks!
Yes, delay time in ms :-)
10 base traps only 😮
Please don’t tell Eric Velentine ❤

@@RichieWynnewhat about 50kg? Is it overkill¿ Or it works better¿

Low number of panels maybe but the room is small so the % of covered area is pretty high. The benefit of small rooms 😁
