Look for microphone able to listen shockwave

[bicave]

Hi everyone,

I wanna look for a microphone able to detect shockwave because most of common microphone can't.
It's appreciate available on DIGIKEY.

thanks

Microphones are either sensing sound pressure (omnidirectional microphones) or sound particle velocity (directional microphones). To determine the suitability of microphones, you would want to specify quantitative shock wave parameters. But I guess, that most diapragm microphones won't stand typical supersonic shock waves. Most people are using small, ruggedized pressure sensors for similar applications.

Shockwave is generated by bullet when travelling. They using microphone, but I don't know what kind of mic.

Measurement microphones form Bruel&Kjaer have a dynamic range up to 168 dB, which should range rather near to a travelling bullet. For even higher sound pressure levels, as e.g. observed with detonation waves, you would want to refer to special designed pressure sensors, as already mentioned. Neither of these devices are however available at Digikey, I fear.
