Basicly you're right. Concepts are correct, and there are many relations between them and many branches from each of them, in a theoric and empiric sense.

Maybe you are confused. Panel has a resonance frequency, and resonator has one too. You can build a resonators array with a panel or more (perforated) please review www.iperf.org. I hope help you. Luck

Hi all: I want to ask if i can use an accelerometer with a different sensivity than original, and if yes, do i have to make any correction, how? Thanks and luck

what accelerometer can be used in a B&K 2513 vibration meter instead the original 4384?

I'm looking for a Bruel and Kjaer 4384 accelerometer, an magnet mounting and a adapter. Have anybody one of that? any information will be appreciated.

Yes friend, I have this book, but i'm looking for an equipment.

Someone already had asked about it, but I want to know if there are more companies offering this class of acoustic absorber? Thanks.

Friends: First, Happy and succesful new year. I'm looking information about human vibration meters, specially respect whole body. Any information will be welcome. Thanks

You can find companies related to ANC here: http://users.erols.com/ruckman/MoreInfo.htm

If I understand your requested info, you could try on Noise and Vibration and Control by Leo Beranek, chapter 10 i think, (jet noise). I hope this help you

Dear friend take a look to federal transit administration (fta) website Luck

you can see on BS 5228 Noise control on construction and open sites. the federal transit administration have some informnatiuon about it: www.fta.dot.gov/office/planning/ep/subjarea/noisevibration.html. I hope help you.

I`m looking for costs of sound intensity meter equipment. If somebody know about sites or companies that sell that, new or used, plesae help.

Friends: i'm asking for the next case: a screw compressor, with twin rotor, that rotates at 2900 rpm. The rotor are a male and female system with five lines. I want to know what are the main frequencies generated by this system?. I'm thought these are near 50, 250 y 500 Hz. I hope understand...
