After i emptied whole apartment for renovation, i heard strangest sounds coming out of street by cars, busses and dogs barking. I thought i was loosing my mind or that my ears were fucked up. I decided to record those sounds and i recorded every one of them. Only then i calmed down

line your room with book shelves

Awesome video. Thanks for sharing.

Yeh. That’s all very well in an empty room, or a dedicated listening room containing just the hi-fi rig, listening chair and maybe beer fridge. But in the average family lounge, carpets, curtains, rugs, sofas, cushions and a whole host of other soft furnishings, are likely more than sufficient to ensure acceptable RT60 levels.

I'm worried that low frequency bass is slowly killing me in my tiny little bedroom

but why don't people like fully dead sound rooms?.. I love it. The "after" sound in this video is way too much reverb for me.

The Great Explainer !!!

Please avoid using archaic units like "feet" if you want to sound professional.

acoustic eh I mean good video

As a musician who has significant hearing loss, listening to KZfaq videos through earbuds for the last three hours, I'm struck by how clear and beautiful the sound of this video is compared to all the other videos I've watched today. Good to know there are people who understand and care about sound.

What about rear facing speaker ports. Would the bass produced be slower and be destructive?

Hope this guy is doing fine! This is helping me with my review. Kudos!

Soooo…. I play bass guitar. Placing my amp in the corner makes it incredibly boomy. Should I place it in the middle of the wall in the clubs we play?

Great video, both narratively and physically.

can i avoid sound by any matts

Just wondering how we would perceive sound if there was no direct sound source and the sound came from reflections on the wall only.

I have a couple 100 pound dogs, things get very dusty and dirty fast. I want to avoid foam and fabric that will become disgusting allergen traps. What are my treatment options?

Good explained. Next time turn volume in your record much more up. the annoying sound is not loud enough.

Holy smokes! An engineer with a sense of humor. Very rare! :)

Some engeneer told a solution to avoid room issues on bass response is to put a line of bass speakers on 3/4 of roomhight....Infinity IRS applied this with their 6 x 12" bass speakers ....?!

I reckon you could fit a few more in there.

Wow this was so cool and well put together- I actually understood the subject for once!

The nerf disc guns are a genius analogy. Fantastic video!

You lost me not even a minute in. What is a wavelength? Is it how loud it is? And what is resonance? Does that mean the sound never goes away?

when i look at the room correction results on my avr i can see there is a huge dip in response at around 80hz from a bunch of channels that dip also did not get corrected by the room correction. is that a room mode problem or a null as the video talked about?

Do your bass absorbers absorb evenly at all low frequencies or do the target the resonance frequency of the room?

This is a great video breaking down the complex topic. I just wish you'd have given credit to the proper name, and credited the discoverer, of the Schroeder frequency.

👍

This is one of those videos which you feel you have to uptove after watching. Not because you liked it but it is common courtesy.

what if, one side has windows and the other doesn't?

عن أبي أمامة رضي الله عنه قال : رآني النبي صلى الله عليه وسلم وأنا أحرّك شفتي فقال لي:" بأيّ شيء تحرك شفتيك يا أبا أمامة ؟ " فقلت: أذكر الله يا رسول الله . فقال:" ألا أخبرك بأكثر وأفضل من ذكرك بالليل والنهار . قلت: بلى يا رسول الله . قل: سبحان الله عدد ما خلق ، سبحان الله ملء ما خلق ، سبحان الله عدد ما في الأرض والسماء ، سبحان الله ملء ما في الأرض والسماء ، سبحان الله عدد ما أحصى كتابه ، سبحان الله ملء ما أحصى كتابه ، سبحان الله عدد كل شيء ، سبحان الله ملء كل شيء ، الحمد لله عدد ما خلق ، الحمد لله ملء ما خلق ، الحمد لله عدد ما في الأرض والسماء ، الحمد لله ملء ما في الأرض والسماء ، الحمد لله عدد ما أحصى كتابه ، الحمد لله ملء ما أحصى كتابه ، الحمد لله عدد كل شيء ، الحمد لله ملء كل شيء " رواه أحمد في مسنده والنسائي في السنن ال

The originality of this is that it offers presentation about the use and practice of concrete building space with approach to the study of enviromental sound and course world which offers a scientific and technical perspective on engineer acoustics.

Wow

Another reason to use corner horns/speakers and make sure your corner speakers have directional control to ensure no more than 90 degrees of dispersion

That tube is so cool

That beats the point of having a sound system the living room

Great video. You do a great job of explaining without getting too bogged down in the minutiae. Much appreciated.

Oh no, I DO want to find first reflections that way.

ceiling way ttoooo high

Would it help if we replace the panels once a day?

lovely

A couch and a rug with curtains is all most people need.

Whish there was a before and after with Music being played

Très intéressante introduction.

Nice video production. I really liked the visual examples and education on how bass works in rooms. You've said that porous absorption is not effective under 200 Hz though, and that's just untrue. If that was true, and the only thing that worked were pressure-based treatments, then you'd never see professional studio builders filling their rooms with rock wool and fiberglass at depths up to several meters. Those treatments absolutely work, way down to 30 Hz, when you build them with correct depth and density. I can support that statement with a real world experience and acoustic testing data. It's definitely correct that as particle velocity decreases the effectiveness of porous treatments declines, that's why airgaps are used. Even without airgaps, fiberglass can damp room modes down very low in the LF. In my control room we have a front-back axial room mode of 35 Hz that we treated with 1 m of fiberglass and slats. The low end is completely controlled. And of course pressure treatments have their place and use. But it's off base to claim that under the Schroeder frequency you cannot use porous absorption. People like myself are doing it with excellent effectiveness.

Thank you for this !!! ]

if im going to film videos and im going to move, is there any special treatment for that, or whats your advice?

Isn’t it funny. Music producers/engineers deploy these devices in studios… and then almost always add artificial reverb. While I understand why, I also understand that some of the most stunning music recordings are those of pipe organs and choirs in immense stone cathedrals. The natural looong reverberation is magical.

Can u please elaborate or short video On commercial overrated foams... do they really work ?

I don’t think it’s as bad as frequency response recorders make them appear because it assumes that we hear direct and indirect sound in the room all the same. I think our brain learns to prioritize the direct sound from the speakers and all the other sounds bouncing around have minimal impact because if it were equal we would have 20db boosts and dips all over the chart and every song would be insanely hard to listen to. I think this is mostly to sell stuff and lack of how our hearing works
