Sound Source Detection
Sound Source Detection
(OP)
I'm living in a rented condo and there is often banging and music coming from somewhere. I'm trying to pinpoint where the sound waves are coming from, ie: exact locations near the door or other areas, so I can make attempts to block the waves or pinpoint the exact unit they're coming from.
I'm wondering if there are any simple devices that can be purchased in order to detect the actual direction and source of sound waves from the measured area? I'm willing to spend a few hundred dollars for such a device.
Any help is appreciated, thanks.

RE: Sound Source Detection
You'll need something to analsyse the signal with, http://www.abravibe.com/toolbox.html for example.
The microphones don't need to be very posh, they need to respond at the frequency of interest, but errors in phase and magnitude response can easily be calibrated out by swapping the two microphones over.
The rather more significant difficulty is that any effective sound treatment is likely to be inconvenient, expensive, or ineffective, often all 3.

RE: Sound Source Detection
It describes the popular two-microphone method very well. We've used an implementation of this for many years on engines to map the acoustic sources. Areas of the engine are marked out and swept individually. The sources can then be ranked. (Some areas often have negative intensity - the are ne absorbers).
