Siren noise from my head audible to others

Patient: When I was 8-10 years old I had a siren noise coming from my head that other people could hear from a distance. The doctors that studied me thought my parents and I were crazy and couldn’t find a reason for “the noise” and it never seemed to happen when a doctor was nearby. I am just wondering if since then there has been any other cases of this condition and what causes it?Thanks
