Studio Bass Trap Build and Test

My take on building the "better" audio bass traps originally published by Ethan Winer. This video is part of a story I'm telling at gearslutz.com, where I'm posting links, pictures and audio related to the studio treatment. Check it out here: http://www.gearslutz.com/board/bass-traps-acoustic-panels-foam-etc/448605-bui...

And yes, I meant to say the lid is made of thin plywood, not fiberglass, and I meant to call the toggle nut a nut not a bolt. ;-)

Really Cool vid Elaine. i want to take control over my control room and live room but i really dont know where to start. Did u post YOUR plans?

[ElaineDiMasi]

@nypdrums - in the Gearslutz thread there's a little more info, but I admit I didn't finish wrapping up my writeup. I do plan to put up more when I get home to NY this fall. :-)

[ElaineDiMasi]

You fellows can type "ethan winer" and "basstrap" into a search engine to see where I'm coming from (youtube didn't allow me to paste a link here). More info is in my gearslutz thread. When I post the results after I get back to NY (october 2011), I'll answer some of the questions I see here.

Thanks for enjoying. I am living away from home this year - I'll post results next fall. I used the mic I had. It's not an absolute measurement (though the specs are flat in the given frequency range). It's a measurement of the degree of cancellation *at the position of the mic* before and after room treatments. The differences are real, though of course the response is not magically flattened, and we would have to go into apologetics for the microphone type and placement if it was. Cheers

Well done. Of interest (and benefit), the membrane and air mass sealed within participate in an interaction that reflects a portion of the incident energy in reverse polarity. This effect is heard throughout the room. In the zone, 0 to 3 feet in front of the membrane, this active effect can be perceived by anyone (even the deaf).

[ElaineDiMasi]

@WestofKevin Thanks for that note! I was able to hear the center one as soon as I installed it in front of my desk like that. My first thought was - oh no, what have I done. I thought what I was hearing was my voice bouncing off of unfinished plywood instead of painted sheetrock. I wonder whether I was also hearing the effect you mention.

Brilliant yet very easy to understand.

@zzzxtreme

You can easily make your own sweep using a synth or VST.

[zzzxtreme]

thanks, ah now i know how to test the frequencies, smart. but how do u get the sweep wave file ?

thanks, ah now i know how to test the frequencies, smart

6-15 blankets hanging mostly in the corners and some shelves in the back and you're golden. Then you can hear the depth in your families voices when they complain about how cold it gets at night!

Im more concerned with sound proofing a room so that the neighbors don't throw a fit then having a perfect acoustic environment...would bass traps be good idea to keep sound from getting outside of the building?

[charlylira]

please talk about the formulas to get a room on an equal response, i use to have them since i studied in a audio school but, i losted them and i like the way you explained, also can you do more videos on how to make variable acoustic traps. Thank you = )

[elliott0]

very informative!

[MrBrandonPeoples]

i'm so confused now lol i wish i really understood acoustic treatment

[MaghoxFr]

awesome video, really helpful. Thank you very much for t aking the time to do it.
