wildcaught Posted October 3, 2004 Share Posted October 3, 2004 Hi, Can someone please give me an idea of how noisy this power generator is when it says "operating noise level at 7m (dB) 65" ? Also, is this reading normal from a 2.5KVA power generator? ================= AC frequency (Hz) 50 AC output voltage (V) 220 Rated AC Output (KVA) 2 ================= Thanks in advance Link to comment Share on other sites More sharing options...
mysteriousredsuns Posted October 3, 2004 Share Posted October 3, 2004 im not too sure but i think noise will always be subjective to personal hearing but from memory 7 meters away reading 65 db is ok but i wouldnt think its ok for inhouse use. would probably be too noisy.

EcHo2134 Posted October 3, 2004 Share Posted October 3, 2004 mate my two stroke victa lawnmower is rated at 65db... that should give u an idea of how loud it is Link to comment Share on other sites More sharing options...
Ben Posted October 3, 2004 Share Posted October 3, 2004 That is a quite lawn mower. 0dB the faintest sound we can hear 30dB a quiet library or in a quiet location in the country 45dB typical office space. Ambience in the city at night 60dB Martin Place at lunch time 70dB the sound of a car passing on the street 80dB loud music played at home 90dB the sound of a truck passing on the street 100dB the sound of a rock band 115dB limit of sound permitted in industry 120dB deafening HTH Link to comment Share on other sites More sharing options...

For every 3dB it doubles the sound intensity so you then reduce the exposure time by half so..... 88dB will have a four hour exposure limit, 91dB - two hour 94dB - one hour 97dB 30 minutes 100dB - 15 minutes 103dB - 7.5 minutes etc etc The 115dB rating mentioned is the industry standard for "peak" noise (ie hitting a piece of metal with a hammer) as opposed to constant noise which would be the type of noise made by a generator. The claim of 65dB at 7 m is very misleading!!!! Whilst 60 - 65dB is generally equivelent to the sound level of a normal conversation thats the noise measured at one metre distance. With noise there is another rule in that for every doubling of distance from the source of the sound that the dB rating is reduced by 6dB. Applying that in reverse if your gen set is 65 dB at 7 metres then it will be 71dB at 3.5 metres and 77db at 1.75 metres and 83db at 875cm. Still not too bad and well below the 85db occupational noise rating but don't be suprised when you start it up and it sounds louder than you expected - move back 7m .

Setup Posted October 5, 2004 Share Posted October 5, 2004 Where did you get the generators? I'm looking for one for the future but have no clue what to get and where to get for a good value. Currently i'm running about 1200watts so what do you guys recommand and how much am i looking at? I had a look at solar power generators but thought petroled ones were better. Solar powered are $2200 including installation in which you can run 5000watts and store up to 12 hours(4500watts/PH)... Solar or petrol? Link to comment Share on other sites More sharing options...
wui39 Posted October 5, 2004 Share Posted October 5, 2004 Go green and go solar Think of all the sunlight that is going to waste. Petrol cost money as well and you'll need a good ventalation to ensure it sucks in air and expels the exhaust properly. If we could convince large corporations to use solar generation as their stand by power (yes diesels are "more reliable") think of space savings that they could have. 5000w sounds like a lot though. What's your elec bill like? Link to comment Share on other sites More sharing options...
wildcaught Posted October 5, 2004 Author Share Posted October 5, 2004 Thanks for the info guys. Where to get generators? Try "Gasweld" Discount Tool Centre. Ph: 1300 667337 Just to name a few, they are located in Blacktown, Granville, Castle Hill, Leichhardt, Penrith. If you get one, make sure it's a Honda engine and not a replica!
