im doin my senior project on car audio its a research paper has to buy 5-8 pages and my product im putting 4 15's in my truck. i need topics and main ideas for my paper though thats the hard part
lulz were had. don't scare the poor kid.Or the physics of common chamber vented enclosures and characterize the inherent phase interference associated with asymmetric vent locations.
Just document your install. Start by listing goals and anticipated issues / challenges. Outline the intended procedure then describe the actual process. Finish with a summary of how close you came to the original goals and what if anything you'd do differently the next time.
you just blew OPs mindWhat class? I have a ton of acoustics reference material I can share.
Research the effect on xmax with common chamber enclosures.
Or the physics of common chamber vented enclosures and characterize the inherent phase interference associated with asymmetric vent locations.
your test was quite flawed... you mostly measured barrier effects and transmission loss. a dB meter is not acceptable for that test as you cannot resolve the amplitude of each frequency being tested. to truly evaluate deadener you need accelerometers or the ability to measure resonance frequency of materials with a narrow band RTA (our narrow band measurements have 1Hz resolution). having the mic in a fixed position means you were also measuring room modes and phase interference that would not be noticeable with a dB meter. nothing in that test allows you to evaluate the elastomeric and viscoelastic properties of deadener. your judges knew nothing about acoustics... i would have given you an "F". //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifMy senior project was kinda on car audio....actually deadener. I basically tested how effective deadener was in relation to frequency. Took all of an hour and if u can BS like me, you'll make a 99 like me and go to the State Science Fair lulz
I'll see if I can find that vid of it right quick...
EDIT: here's the vid

I put a wall in front of the speakers lined with deadener and then a db meter on the other side of the wall and tested readings of diff frequencies with and without the deadener.
It was stupid easy. Its just all in how u make it sound. Like I said, I made a 99 on the project, got first at the Region Science Fair, free trip to Athens to place Third at State, got a couple Grants from the Army, offered an internship for some engineering company in Macon and a few other small awards. Its all in how u sell yourself man.
