Hi all, I am planning on using several Audio Moths to determine if there is a presence of ultrasonic noise in several classrooms on my campus. Along with this, I will be taking room mean square measurements of the sound waves in order to determine typical sound pressure levels in these environments. I need the sensitivity of the audio moths in order to do this, but cannot seem to find this value. I am interested to see if anyone knows more about this, or can possibly point me in the right direction - thanks in advance!
