- - In this video we're going to talk about small room acoustics and why diaphragmatic absorption is the only low frequency absorption technology that has sufficient horsepower to tackle small room problems. Watch the video to find out more!

Lately I've been learning a lot from this channel. Thank you a lot!

[@AcousticFields]

Happy to hear that!

[@shotaro_music7625]

Thank you for helpful nice lecture🙏🙏

Dennis if a big base drum can create deep low freq, is it possible you could make a base trap that's like that of a big base drum??? I was thinking if it can produce it, why could it not trap it with the right designing.

[@AcousticFields]

Diaphragmatic absorption is a "bass drum" absorber. It has a diaphragm, the drum head, it has a cabinet with x density which is the drum itself. Unfortunely, neither the drum head or the drum itself has enough density to be effective as a low frequency absorber. It has the proper depth but lacks cabinet and diaphragm density.

I like this guy, he's a bit like stereotypical granpa - his voice is like "I've seen two world wars, and what can you youngsters know about life"
- I mean no hard feelings, just my impressions, definitely positive ;)

[@AcousticFields]

We have actually tried and tested all of these absorption "technologies" in the markerplace. Only 2 worked close to advertised. None come close to our diaphragmatic carbon absorbers which are a direct response to to all of this failure.

[@mosiowaty1573]

yes, I believe that you've done a lot of testing - thus the "two world wars" metaphore. However, I'm not yet building any hearing room, just car audio - my car is the only constant in my life. I'm watching your videos because I'm looking for better understanding of acoustic theory (and practice). And yes, corner bass traps made out of foam do seem to suck - I've seen them a couple of times, but the room's low frequency acoustics seemed to be far from being even decent.

Hello Dennis. Where can I message you about the possibility to have your technology shipped out of the US if that is possible? Thank you

[@AcousticFields]

We ship internationally. Send your request to: [e-mail]

@@AcousticFields Thank you, the email was sent. Have a good one!

[@acecatman]

what are your thoughts on free-hanging sheets of mass-loaded-vinyl as a surface for bass absorption? have you ever tried putting one in front of a BDA or ACDA to see if it improves the response?

[@AcousticFields]

Mass loaded vinyl by itself is not a lower frequency barrier material type. It is designed for middle and higher frequencies. That said, MLV has application in lower frequency barrier designs when used in conjunction with other material types.

[@acecatman]

@@AcousticFields well here's what I mean, let's say you have a small room and you already put in the maximum amount of BDA's that will fit. One of your competitors has instructions for building what is essentially a frame with an air gap, a loosely held sheet of MLV, another air gap and a foam panel on top, and they have impressive test results with this product in the low-end frequencies. So I imagine it would be a good way to get more horsepower out of the available space since you can hang these where you can't put a heavy BDA type cabinet, i.e. upper walls and ceiling.

Awesome!!!

[@AcousticFields]

Thanks!!

👍👍👍

[@AcousticFields]

We appreciate your consistent folloowing and support. Is there any topic you would like covered in our video format?

[@djhmax09]

@@AcousticFields Thank you for all the free gold nuggets of knowledge!
That's a hard question since you've covered a LOT already. But I'll throw out some ideas: 1) I really liked the debunking myths one so if there are more you can think of that would be great. 2) How about comparing other schools of thought in acoustics? I hear advice from what seem to be well-known people from the industry and their methods are, let's say, "different" in regards to acoustics. An example would be to allow reflections in the room to remain because our brains expect there to be some. As a result, they claim it to be a more natural-sounding approach.
If I think of more I'll be sure to comment down in future videos but that's all I have for right now. Thanks again Dennis!
