Then it should be easy for you to provide detailed steps to allow anyone to reproduce your experiment.

What is the frequency? You clearly must know this, as part of demonstrating that it "is always present", which would require you to use a spectrum analyzer or similar technology to identify this signal from the rest of the music or other audio. > If you switch off the playback > and put the headphones away, you will (hopefully) recognize a pressure > and and whistle in your ears. I am sure that those who attempt to reproduce your experiment will watch for such symptoms, if and when you provide reliable steps for doing so. > This noise is dangerous and destroys your ears! What is the frequency? At what volume does harm occur? You clearly must know this, to have consulted with an audiologist to determine the effects of such a sound. Or are you an audiologist? > You can not fully recognize > the level due to the high frequency. But you previously stated that it is "easy" to hear and that anyone who listens to it will experience symptoms. Now, nobody can hear it. It is difficult to reconcile these mutually exclusive claims of yours. > But, the noise destroys your ears!

And if you can provide proof of your claims, we can certainly work to notify all the proper authorities about the health issue. Please write up the steps to reproduce the problem, the audio details of the signal (e.g., frequency range), and your evidence that there is a health hazard for listening to this signal.
