Impact location, using four sound sensors.

[MarcelDv]

Another Question,

How large do you guys think the effect of surface tension would be..
at this moment the target is made of a canvas material loosely fitted..

Would a hard surface improve the accuracy, and then if i use something rubber,
as the impact surface, would that have a huge impact on accuracy..

Conveyer belt works great as a target back stop as it heals (does not leave holes)
but i am concerned with the effect rubber would have..

I am rebuilding the target area, so i am considering all aspects that could affect accuracy..

Just did some interesting Math... Do you guys agree with the results..

... with the speed of sound at 340m/s
........
does this make sense.. or have i smoked something not good for me :-)

Unless your target is made of air or smoke, you have smoked something.

340 m/s is the speed of sound in air at normal pressure and temperature.
In other materials it is significantly different.

The frame is constructed that the Mics listen in the thin air/smoke  ..
so the sound of impact will travel trough the air, it is not measuring the surface
vibration..

Depending on the target material the sound should be a hard thumb,
this i say based on me being on a military spec shooting range where you
sit bellow the targets in a bunker, and there i could hear a very distinctive thumb
sound on impact..

But yes, i did not smoke anything on the speed of sound :-)
the calculations maybe.. :-)

Dragging up an old thread, I know. I have found a few similar threads. Just wondering if this idea was ever actually worked out? Looks like it died in 2010 and then resurfaced in 2013. I am soon to start a project using the same idea, just hate to find out it's not possible. Seems like some great minds have been hard at work already.
