Hello guys,
I am looking for a arduino-applicable sensor for acoustic emission, and have no idea. Do you have any suggestion? Thank you very much.
please define "acoustic emmision"
What do you want to detect? - frequency profile?
the more you tell the better answer you can expect.

Hi, thank you for your reply. I would like to monitoring the condition of CNC machine cutting tool

not enough information so I can't help you further
I guess you want the profile the the sound spectrum, so if the CNC gets stuck, you can stop and look at it.
So it comes to the point of measuring both frequency and intensity of the sound.
That is laborious. And once get the spectrum, you may want to see what is the sound form (profile) of a particular situation. This is another task in hand. You may not enjoy stopping the machine by calling your cat. :-))).
Why not try using a vibration sensor?
You can detect unusual vibration of the machine, because anyway the sound is a "byproduct" of the vibration.
But even in this case, you may want to reproduce the sound in order to teach your program when to react.
