Rockin' here in the UK with the Doors. God, I love this band! Even more when the sun is shining.
Talk but not walk?
Hi Guys
This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?
I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?
You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?
I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?
thanks, be polite

glupson. I'm back and my answer will be separated in to two posts. About the diffusor. As I probably linked to in the post you saw, I bought this one: https://www.acousticgeometry.com/products/curve-diffusor-crosstown-birch/ I ordered it in a coffee bean fabric color that actually looks quite nice. It does not noticeably attract dust and if it does, it doesn't "show" dust at all. It looks like a sturdy fabric that will last a long time, and look new for a long time. Besides, vertical surfaces tend not to accumulate dust anything like horizontal surfaces anyway. So, dust is the very last concern I have with this thing. I haven't had occasion to clean it and can't imagine it's going to be necessary in any acute way in the future. But if anything gets on it, a little dust ball or whatever, it easily brushes off with the hand. I did not want to introduce any new permanently affixed room treatment if I could help it. The size of this diffusor makes it perfect for my purposes. I don't mount it on anything, I simply lean it against the area of sidewall near the speaker that I wish. It's very easy to lift in and out of the room - I store it in my office/source component room and it hides out of the way nicely. I wasn't totally happy with the diffusor in the classic "first reflection" position - though that is probably due to the fact it had to be closer than ideal to the speaker. But I ended up finding a happy spot just beside to the rear of my speaker that seems to add a bit of snap and focus especially to central images. I'd give these things a thumbs up as something easy to play with in terms of acoustic treatments. |
