Bombs and bangs

7 04 2007

Is it a rock? Is it an old doorbell? No, it’s a landmine. Kyle sent this photo from the Libyan desert where they are drilling for oil, these are just left as found. Oooerr!

In Northern Ireland, where I grew up, bombs and bomb scares were commonplace.

The Irish have a different way of dealing with them than the Libyans 😉
(The robot has since filed a deafness claim….)

When the bombs fall, and then all is silent, the lives of the survivors may also be silent. Bombs are very loud. Noise levels as high as 110 to 130 decibels have been documented in bombing practices. (Other war-related sounds can be painful, such as shotgun blasts or the sound of jet planes taking off from as little as 100 feet away). Being exposed to sound that loud, even once, can cause hearing loss. Any sound above 85 decibels is considered a potentially damaging threshold.

During World War II, many people acquired hearing losses due to exposure to bombing raids. In Northern Ireland, many people have gone deaf from the noise due to bombing. Bombing exposure may be responsible for at least some cases of sensorineural hearing loss (SNHL) in babies born to mothers who have lived through war. During the war between Iran and Iraq, more children were born with unexplained hearing losses, and their mothers had been exposed to bombing. Other terms for the effect of bombing on ears are blast injury deafness and acoustic trauma. Explosive sound can damage all parts of the ear (it can tear membranes and move bones around), leading to either temporary or permanent hearing loss.

Did you know, a man’s hearing was saved by his Apple iPod earphones in the recent London terrorist bombings! Oh yeah, and you know, one of the great advantages of having a hearing loss is that I can listen to my iPod all day, as loud as I want, as my ears are wrecked anyway! It’s not advisable to use earphones for long periods at loud levels.

In that picture of a landmine, is there a three-legged duck wearing an invisibility cloak?

We use invisible three-legged ducks to help us find leftover nasties like anti-vehicle mines (shown above) – so that if they step on them (as is likely with 3 legs), they blow úp, but as they are invisible, they don’t leave a mess but we see their feet lying on the ground.

Hope that clarifies it for you Dale 😉
