Correct, and he's quite wrong in his assumption. A person with tinnitus would hear a similar noise wherever they went. The Hum is different in different locations around the world. > I have excellent hearing like you, Matty. > I have some technical expertise ,but not ehough resources or time > currently for the Hum work needed. > It is very elusive and also ,as you say, easily masked by random > extraneous noise of varying kinds. > That doesn't 'excuse' the Hum though. > The big question is do YOU hear anything other than the extraneous > noise that could be labled Hum? I don't understand what you are asking. Clearly I hear the sound of distant birds and crickets. I have not heard any Hum that is not explained by a ship's generator. I've camped the night out in the countryside where the silence at night is astounding. > I remember a poster from earlier days this forum mentioning a group in > the wilds all hearing a HUum that was persisting. > Could that REALLY have been a long distance motor and would they all > have SUCH good hearing co-incidently? > Not in my book ,Matty. That kind of hum is certainly hard to explain. But the low frequency part of the noise from a large motor could travel a very long way. Here in NZ, it's quite possible that someone has a generator within 20 miles. I am able to detect the direction that sounds are coming from. It should be just a matter of going to a variety of locations and plotting the directions on a map. > c) You are assuming the Hum can be readily found. I think JD will > disagree there. The Hum that I heard was not easily found. At 2am I started by driving in the direction of the Hum. As I got closer the Hum was muffled by general noise at the port where the offending ship was moored. >From a hill 200 metres from the port, I could hear the same noise that I was able to record at my home 2 kilometres away. There was a great deal of other higher frequency noise which made a recording close to the ship almost impossible. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hum Sufferers" group.
