Hi Luca, I am Barry Fletcher. I have suffered from the Hum since 2000. I am sorry to say, the noise I hear, known as the Hum does not compare with your recording! The Hum is far more complicated in tone and extremely irritating. I have noted several regular, and even more frequencies, ranging from 30 to 5000Hz. The noise you are demonstrating sounds like a domestic cooling fan. Which sounds quite relaxing. The Hum is not relaxing. As soon as it starts it will get your attention immediatley. It will drag you from the deepests of sleeps. It will make you very angry! Regards Barry
