how would i integrate a microhone onto labview and what boards would i need

[stephen hume]

i am currently using a 1992 version of labview along with an sxci module to measure the displacement and load on a punching machine. i would further like to integrate a microphone onto this munit and i would be very grateful if you would be able to provide me with information on how to do so.

Good Morning Stephen,

You should consider our NI-4472 data acquisition board, which is designed specifically for acoustic and vibration measurements. We also have a excellent library for LabVIEW 6.1 for sound and vibration measurements. You will find this library in our LabVIEW add-on toolkits.

Can you tell us more as to how you expect to interpret your data? At National Instruments I specialize in machinery monitoring with acoustics, vibration, electrical power, and machine vision.

Hi,

Newer versions of LabVIEW have standard sound I/O functionality (through the
soundcard).

Buying a new LabVIEW version (upgrading) will be cheaper then buying
suitable hardware, and programming this functionality.

Regards,

Wiebe.

Hi Stephen,
I never used 1992 version. The earliest one I used is LV3.x back to
1995. So I don't know if you can call some dll in 1992 version. In
LV5.1.1, they provide a set of vis for reading and writing the sound
data. but I don't think you can downgrade those vis to be used in your
version, but those vis just call a dll that NI provides
"Lvsound.dll", so
I am thinking if you can make use of this dll.

Stephen,
Can you explain the question further? As I read this you could be
asking :
1) how to connect the microphone to the sxci hardware, and/or
2) how to configure Labview to record and analyse this additional
signal

In case 1) it would be advisable to contact the microphone
manufacturer as they probably sell amplifiers that will power the
microphone and convert the microphone signal to an appropriate voltage
level for your sxci hardware.
