Axiom Home Page Forums General Discussion Technical Questions Room acoustic question

Thanks for posting that Alan. Very informative as always!

Its time to get down to business.

Very interesting Alan(and Floyd). Tks.

It makes me wonder how many people have spent so much more $$ on "upgrading" speakers, when all they needed were some simple room treatments.

Alan, it's great that your former association with Dr. Toole at the NRC has allowed us to have the benefit of his knowledge here.

Okay Bruno, you heard Dr. Toole; get that mattress out of the bedroom and put it up on the wall behind you!

Incidentally Alan, the "auditory reflex" which you mentioned above, in which the ear tries to protect itself against very loud sounds(only partially successful, unfortunately)is briefly discussed by Dr. Toole at pp. 437-438 of Sound Reproduction.

Page 437. I'd have to be reading tolkien or something interesting to get that many pages in!

This is true and could probably be the case with Bruno. However, Dr. Toole and Dr. Olive also stress when buying a system is to spend money on quality speakers above all else and just not put them in too live of a room to begin with. Minimize room treatments. In recent postings by Dr. Olive stresses over treating a room as waste - the same point Dr. Toole was making towards the end about Bruno's situation.

Very cool to see the response from Dr. Toole, thanks Alan. I was going to post a couple follow-up questions but instead I ordered the book. I love/hate Amazon.

If WAF is a consideration, you might try a large plant or ficus tree in each corner behind your listening spot as well as a bookshelf on your side wall.

How lucky are we here that we have so many experts but also experts who are friends with experts. Best of all, things mostly stay light and entertaining while we learn.

Back when I used to be more "hands on" in computers and networking, I would frequent a few technical forums and while they were extremely good places to learn and have assistance from top minds in the business, there was always zero entertainment value and you only asked question that was "worth" of their expertise or that was probably going to be a thread with zero replies.

Sorry, I've been away for a few days. Thanks Alan and Dr Toole, what a great explanation!

I also thought it had more to do with reflections more than the amp, specially after playing around with bed sheets and pillows, but wasn't really sure why, now I know

Unfortunately, I don't have a dedicated room, I use my living room that is 20x11 ft. To answer Dr., I seat in the center of the long side wall and my TV and speakers are across. My couch is against the wall and on top of that, behind the main listening position is a bay windows so no acoustic panel can be there. As for the sides, they also unusable for acoustic treatment, one side is open towards the hallway, the other has a bay window. The only thing that could really be done (on top of bringing the mattress, pillows, bed sheets, etc.. into the living room ) is adding a bit of furniture and putting thick curtains on the bay windows.

Thank you all for your help, this has been great.
