When I tested with ultrasonic on speaker no matter what the volume I notice a very slight uneasyness in my ears, so I never used ultrasonic more than 2 minutes and don't intend to do it more.
But thanks it's cool know that, I may not be fully objective when my ears are at stake.
shannon mentioned somewhere on the forums that it should be around
-40 db to -60 db? Did you guys miss that? It can easily be checked on frequensee the volume that you have the ultrasonics running on ?
