Victor Porton's Personal Weblog

I have sent the below message into the Perm Regional Human Right Center, and also in a forum of the Russian Human Right Network.

In an unclear reason in my personal room often is felt a sound of very high frequency (I suppose, it is above 20Khz, the approximate border of ultrasound), and sometimes also a sound of very low frequency (near to the border of infra-sound). I suppose that these sounds may harm human health.

Further, I will call this problem (presence in my room a special unknown noise producer) acoustic psychotropic weapon.

This longs already many months (probably several years), I have not wrote down the exact time when this acoustic phenomenon, but in various reasons which I prefer to not tell about, I have not called the state authorities about this problem; with the exception that I have called the police, but my phone call was left without a consideration (they have hanged up the phone).

I require to make known the reason of the noise and free my personal room of psychotropic weapon.
