Troms├»┬┐┬╜, 9006 · 2019-01-09 · from the WORLDHUMMAP archive
Sounds like large steel sheets/panels of metal being grind together. It sometimes also reminds me of a huge diesel engine running in the far aways. Like a rumbling. I�ve been hearing these noices almost every night during the summer since age 15. The nights I�ve pondered upon what the source might be, is uncountable. Especially the rumbling sound have kept me awake and has become my �now-I`m-certainly-home� sound. Thing is, of all the places I have been to and lived, this is the only place I have ever heard these exact kinds of sounds. Troms� is a port city, so it`s not uncommon for cruice ships, fishing convoys etc. to make sounds by the harbor. But out of summer break boredome, I used to bike around at night to locate the source. Down by the harbor, at the other side of the island(there is a sand refinery) and yeah all over. Never found it. Source appears to be moving away, similar on how rainbows run from you. We don`t have railroads and only two-way traffic roads. Population at about 65k and usually very quiet at night. I like it.the sounds. It`s a sign that I`m truly home. I may never know the source, but I like to lay awake thinking and pondering on the occasions I`m visiting my childhood house.
What they reported

Pitch: For the engine sound I`d say 170hz, and for the scraping it can start from 200hz and rapidly reach 2000hz.

Changes with weather: I can not recall hearing it while sunny(polar summer night). I associate the hum with overcast/hight clouds. I have experienced it both on cooler nights(typ. 3C) and rather hot ones(typ. 15C). I also remember hearing it when sight has been good, like no low hanging clouds or fog.

low, steady background rumble I wonder whether my tinnitus hiss originated from computer cooling fans, and the ticking from my bedside clock, and the Hum from 50 Hz A/C circuits. I have hear…
