The Hum is a phenomenon, or collection of phenomena, involving a persistent and invasive low-frequency humming, rumbling, or droning noise not audible to all people. Hums have been widely reported by national media in the UK and the United States. The Hum is sometimes prefixed with the name of a locality where the problem has been particularly publicized: e.g., the "Bristol Hum", the "Taos Hum", or the "Bondi Hum".
STRESSED-out locals have demanded an investigation into the "Bondi hum", a strange low-level background noise described as being like the sound of a truck engine or industrial fan.
BONDI residents have always claimed their patch of Sydney has its own special buzz. Problem is, it's driving some of them crazy.
To those who can hear it - it is not detectable by everyone - it is incessant and it has been going on for years.

Listen into the audio for a few minutes, that's when the metallic sounds start.
I am betting this is akin to what you guys/gals are hearing.
Exploding head syndrome is a form of hypnagogic auditory hallucination in which the sufferer sometimes experiences a sudden loud noise coming from within their own head. The noise is brief and is usually likened to an explosion, roar, gunshot, record scratch, door slamming, loud voices or screams, a ringing noise, the sound of electrical arcing (buzzing) or a thud.
