The ACDA Series

August 7, 2018 No Comments

Let’s talk about our ACDA series. Now, what does ACDA stand for? Activated carbon diaphragmatic absorption. So it’s a technology I created about 15 years ago and I did a lot of work in small rooms, corporate boardrooms, built a lot of office buildings, a lot of rooms where there was audio issues in it.

Quadratic Diffusion

July 31, 2018 No Comments

Let’s talk about quadratic diffusion. Diffusion in general causes a lot of difficulty for people and I get that because there’s a lot of terms and explanations in the literature that really just aren’t valid at all.

Is Your Room Working With Your Music?

Is your room working with your music? I get a lot of calls and I see a lot of room forms that come in where I’m really wondering who’s working with whom and the situation is the room fighting the music, is the music fighting the room, does the client just not know what’s going […]

Room Amplitude & Frequency Response

June 23, 2018 No Comments

Let’s talk about room amplitude and frequency response. I get a lot of people that call in and send their measurements of their room and I have to remind them that there are certain qualifications to those measurements and we need to understand what really a flat response in a room is all about.

Echoes, reflections, reverberation time, a lot of these terms get confused and I thought I’d just illustrate some characteristics of echoes and put some time signatures on them and this will give us some feel or idea and separation. These are complicated things to understand and the definitions behind them are very empirical and if […]
