Even though insanity doesn't run in my family, it may soon start to. I'm living in Norway, but this is universal except for London apparently. Over a year and a half ago, they began major renovations to a school right by where I live. It's actually several buildings, and it is a major buildup. We've managed to put up with a lot of inconvenience, parking, large trucks, Saturday work, lots of noise. But the ONE thing that is driving us insane is the backup warning beeps coming from trucks, earth movers, etc. at times we are hearing them, often several at a time, throughout an eight or nine hour day, more than not hearing them. It's almost, but not quite, constant. This was the "brilliant" idea that came out in the seventies. I can't see that any change has happened even though technology has moved on quite a bit, there are way better solutions, not just for the poor souls within a large radius that are forced (even in the house with windows closed) to hear every time a machine or truck backs up (which they apparently do more than they drive forward) but also for the supposed safety issue for workers on the site. Options other than the ear piercing, stress escalating beep beep beep beep might include, replace with backup camera, backup sensor (as many autos now have, that the DRIVER know if he is about to hit some one or thing), flashing yellow light (as many forklifts in warehouses have). At the very least a sensor to adjust the volume to the surrounding noise, as manufacturers all these years just set them at highest possible levels because they can't predict the ambient noise level. Apparently the only place on earth that has addressed the proble, is London. They have enacted some laws, after recognizing the bad effects of stress, sleep, on inhabitants and possibly also that on construction sites the beepers go off so often it is the "boy who cried wolf" syndrome and they ignore the noise as much as can be. These backup alarms are designed to be piercing, to get attention (it's an unnatural noise that doesn't decay as normal sounds do but sounds wrong to humans) at db levels above those that cause hearing loss, basically to cause alarm in humans, in a very large radius from anyone actually in danger of being run over. I've worked on construction sites in my youth, and I always kept an eye out for and stayed away from large machines that backup more often than they move forward and are unpredictable. Ok, enough ranting, but my god....what a stupid solution to a problem. Even more so nowadays when there are (inexpensive) alternate solutions that probably would work better. This doesn't seem to be on any city, state, or federal regulatory bodies radar. I wonder how many accidents result from folk being bombarded by this ugly noise pollution, after losing sleep, stressed, etc. Anyone else bugged by these? I think we have about six months more of this particular hell. From 7 a.m. usually until 7 p.m., weekdays and Saturdays. Sunday is the only day we are beep-free. To tie into aviation (even though it is hangar talk, so no need) living next to a small airport would be heaven compared to this. I mean, I'd like to anyway as I love the sound of small planes, and all, but even if I wasn't into flying, no contest...yet there are rules governing small airports and noise, but contruction (here it's up to five years or so...being called "temporary") site rules mandate use of these damned noisemakers from hell.
