Posts Tagged ‘Rumbling noise’

Here is a difficult and poor recording that probably should not have taken place on this blog site, except because this is a recording of „HUM“.
This is the second Hum recording I have managed to record. In the first one, the origin of the sound was obvious, but in this recording the rumble, or drone sound, is slightly incomprehensible.
This recording was recorded in quite a bit of wind. I therefore had to hide the microphones behind a small stone cairn which in a way affects the recording and is heard differently in different headphones. It was a total coincidence that I heard this HUM because I was not walking or riding a bicycle, but in a car, which usually takes away all natural experience.
There at the top of the Vikurheiði heath I decided to stop and brew myself a coffee. That’s how I became aware of the HUM that filled the air around me. I somehow couldn’t figure out where the sound was coming from. It was coming from literally all directions, but somehow I convinced myself it probably originated from the mountaintops beyond the fjord. I tried to listen for engine noise through this rumble noise, but it wasn’t exactly clear, except twice. 
The remarkable thing about this noise was that, considering the wind and turbulence in the air, the sound was surprisingly loud. Not least if the sound originated from the aluminum plant in Reyðarfjörður, which was 17km away (in a straight line). Later that day it was confirmed that this noise was not heard from the aluminum plant.
Out in the fjord were two feeding or service boats around aquaculture. But they weren’t moving so the sounds were hardly coming from there.
At the pier by the aluminum plant there was a large bulk ship that turned its exhaust pipe towards me. But it was motionless the entire 3 hours I was up on the heath, so the sounds definitely didn’t come from the ship’s main engines.
The only explanation I have for the origin of these sounds is probably this:
The mountain slopes in Reyðarfjörður are many shaped like parabolas. They can therefore amplify sounds in certain places and directions. I therefore assume that the sounds came from the bulk ship’s generators, mixed with traffic noise in the fjord, as well as noise from the aluminum plant.
It can be assumed that this HUM will be heard differently in different headphones or speakers. Therefore, it should not be surprising if some listeners are disappointed.
Quality open headphones are recommended while listening at low to mid volume.

Whatever the mainstream media says, the Paris talk COP21 was a fraud. The outcome was almost nothing, just promises. For me and many others is it too late. The chain reaction has already started so radical actions was needed at last sixteen years ago.
Paris talk was tailor made for investors, corporations and politicians with different needs, probably to make different outcome from previous conferences.
I have wait for political actions all times since beginning of this century so I was really hoping for radical actions after COP21.
The only thing that Icelandic politics brought from COP21 was mostly a nonsense. Icelanders were already doing most of the “solutions” for other reasons. Icelanders will just plant trees and fill up drainage ditches to restore swampland. When investors are ready somewhere in the future, Icelanders will change fossil fuel cars into electric cars.
At the same time Icelanders will increase tourism, even though extreme growth in tourism last decade has already damaged the nature with following pollution and intrusion. Icelanders will also keep on making cheap power for antitrust corporations by building more polluting power stations. They are even going to search for oil well in the North Atlantic ocean.
So as so many earthlings Icelanders intend to continue their greedy and polluting lifestyle.
We are in War against Mother nature like we are all brainwashed by Sauron . We are not only polluting the earth´s atmosphere with poison gasses. We are also polluting the ground, the oceans and fresh waters with dangerous materials and gasses. Irritating audible noise is now everywhere, from the sky, on the surface and in the ocean.
Unpolluted space on our planet is now rarer than gold, in fact more valuable too.
I want to dedicate the accompanying recording to our foolish lifestyle. It was recorded on Mosfellsheiði, east of Reykjavik 25th of July 2013. It should be a quiet place, far away from busy roads in beautiful open landscape. But instead a rumbling noise filled the air from all directions. The recording contains “fossil fuel cars and air traffic”. But the loudest steady noise comes from Hellisheiðarvirkjun, a geothermal power station in more than 10 km distance. It normally blows huge amount of gases into the atmosphere. It is mostly hot steam but is mixed with toxic gases like carbon dioxide (CO2), hydrogen sulphide (HS) and also substantial quantities of hydrogen (H2). Other gases such as nitrogen (N2), methane (CH4) and argon (Ar) are in the gas mixture, but in lesser extent.
Quality open headphones are recommended while listening at mid-low level

Erum við heilaþvegin af Souron?

Loftslagsráðstefnan í París COP21 var mér mikil vonbrigði. Ég hafði vonast eftir mjög rótækum aðgerðum STRAX, en niðustaða ráðstefnunnar varð aðeins í grófum dráttum sú, að fyrirtæki og fjárfestar þurfa að huga að í lotslagsmálum á næstu árum. Það er einfaldlega of seint.
Enginn þorir að takast á við vandann. Menn ætla bara að bíða og sjá hvort það sé nauðsynlegt að gera eitthvað og vonast svo til að tæknin bjargi öllu. Flest okkar hafa séð hversu skelfilegt ástandið þarf að verða svo menn taki nýja stefnu. Nægir þar að nefna mengun í iðnaðarborgum Kína. Fátt bendir til annars en að ástandið verði eins á heimsvísu. Það er því eins og mannkynið sé heilaþvegið af “Sauron
Framtíðn er því ekki beinlínis til að gleðjast yfir. Því vill ég tileinka upptöku hér fyrir neðan viðfangsefninu. Meðfylgjandi mynd er tekin á upptökustað. Allt virðist þar í fljótu bragði óspillt og ómengað. En það er ekki allt sem sýnist. Í loftinu er óvenju mikið af óheppilegum ósýnilegum gastegundum af mannavöldum eins og frá Hellisheiðarvirkjun.
Hljóðritið gefur aðeins til kynna hljóðmengun á stað þar sem ríkja ætti “þögn” ef mannfólkið hefði haft vit og rænu á því að þróast í sátt og samlyndi við Móður náttúru.
Mælt er með því að hlusta á upptökuna í góðum opnum heyrnartólum og á miðlungs- lágum hljóðstyrk.

About 30km east of Reykjavik capitol is Hellisheiðarvirkjun a geothermal power station. This power station uses energy from drilled wells in the surrounding area.
In the drilling process it is necessary to let the wells “breath” or “blow” for a while. When it happens it is extremely noisy when the energy is wasted into the atmosphere, mostly as a hot steam in mixture with toxic gas like carbon dioxide (CO2), hydrogen sulfide (H2S) and also substantial quantities of hydrogen (H2). Other gases such as nitrogen (N2), methane (CH4) and argon (Ar) are in the gas mixture, but in lesser extent.
The rumbling noise from blowing wells is so loud that it can be easily heard in far distances (up to 20-30km, depends of condition).
It was easily audible when I was on my way east of Reykjavik on a cycle trip last summer. I was cycling Nesjavallavegur (road) when I decided to record this noise. The power station was in about 10 km distance, but the blowing wells were somewhere between in 10-15km distance, probably behind the mountain Hengill.
This recording was made at 3am, 24th of July 2013 at Mosfellsheiði. The weather was calm, but cold, very humid and fogy.
Keep in mind, this is a “quiet nature recording” so you should not play it loud. On the field the birdsong was barely audible.

Orkusóun

Hér er á ferðinni upptaka frá því 24. júlí 2013, þegar ég fór í stutt helgarferðalag austur fyrir Fjall. Þegar ég lagði af stað var vel liðið á kvöld og skollin á blaut og köld þoka.
Þegar á Nesjavallaveginn var komið varð ég var við miklar drunur ofan af Hellisheiði en þar blés borhola út orku og eiturgasi engum til gagns. Drunurnar virtust fylla loftið fremur en að koma úr tiltekinni átt svo ímyndunaraflið fékk að blómstra. Það var ekki laust við að maður léti hugann reika, því þar sem maður átti að venjast þögn á þessum tíma sólahringsins voru nú þungar drunur allt um liggjandi sem hér um bil kaffærðu söng sumarfuglanna. Nálægð við helvíti eða heimsendi var manni efst í huga þar sem maður sniglaðist einsamall eftir veginum fremur kaldur og blautur í dimmri þokunni.
Rétt eftir að hæstu hæð Mosfellsheiðar var náð ákvað ég að staldra við og taka upp þetta sérkennilega andrúmsloft sem þarna ríkti þessa júlínótt.
