Sound sensor for a wind tunnel

Hey,
I am building a small scaled open wind tunnel and I would like to measure the sound in my test section.
What kind of sensors would you recommend to me ?
Thanks for your help !

Hi Antoine,

To really know what’s going on, we recommend an Audio Analyzer with of course a sound sensor module.
DFRobot Audio Frequency Analyzer
Gravity Sound Sensor

All the best,

hello

i have tried a sound sensor from sparkfun but it does not work properly. it detects sounds like hand claps but the analogic signal does not increase when i power on the music on my pc
it seems that sensor detects only quick sounds
