Waiting on someone that has the tools to find the exact frequency,(reply>)," I'm assuming you're talking about <a href=""https://www.youtube.com/watch?v=RA5UiLYWdbM&amp;t=4m00s"">4:00</a> onwards. I don't know the frequency because it's silent for me (I'm 25", and I dont think its because of my headphones).<br><br>edit: actually I can just hear it if I turn the volume up to max.
