generator noise question

I have an upcoming trip where I will need to use my RV generator but noise disturbances could be an issue so I wanted to get the input of others here to ensure that there are no holes in my thinking.

We will be staying at a relatives home and sleeping in our RV. I know that the home only has 15 amp electrical circuits and our RV has a 13,500 btu air conditioner. This will be in July where temperatures could be beautiful or could be 96 and humid so I want to be prepared to use the generator to run the air conditioner to cool down the RV at sunset with the intent of sleeping overnight with it off after it has cooled down and I can turn on the Fantastic Fan.

The home is part of a lake neighborhood so the side of the house that fronts the street where we will be parking is really the back of everyone's house from a functional perspective. Everybody uses their house on the lake side which is the opposite side of where the RV will park. Where I park the RV, it is approximately 35 meters to the nearest persons home.

I have a Generac QP40 and from the information that I can find this generator is rated at or below 65 dB at 7 meters. So, if my math is correct, by the time the sound travels the distance to the nearest neighbors home the generator noise will be down at approximately 52 DB. It is my opinion that a noise of 52 dB during daytime hours is extremely acceptable and not a nuisance to anyone. Plus, the way that these houses are set up by the time you get across the width of the house and into the backyards on the lake side where people actually set, the distance will be even greater and the noise will dissipate even more.

Bottom line is I don't think I will have a problem with my generator disturbing the neighbors. Does anyone disagree?

  • If you absolutely need to run the generator, see if you can place a noise baffle between the generator and the neighbours . Bushes work well, as does plywood, wall board, etc. Ideally three sides and don't forget the top. Aim the open side where there is open space. The baffling is equivalent to a lot of distance.

    It is not just the intensity that affects people. The length of time they can hear it makes them more attuned to the sound. I had to deal with 60 cycle hum at work, and even 40 dba would draw complaints, because it was continuous.
  • Where is the electric panel? I would be adding a circuit if I could. Even if I needed a 150' cord temporarily.
  • You should be able to run from a 15 amp outlet easily as long as you don't use an undersized extension cord and keep all other electrical loads minimized.
  • I run my AC off 15 amp outlet - I switch the fridge to gas and make sure my batteries are charged so the converter isn't pulling excess amp. I use a kill a watt to monitor voltage. Helps if the house outlet doesn't have any large appliances or sources of large electrical draws.
  • Take it for what it's worth but I have run my 13,500 BTU air conditioner on 15 amp service on many occasions with no issues. If there is a 15 amp breaker in the line it should protect against overheated wires but not too likely to have any issues like that. Just don't leave the water heater or fridge running on electric at the same time.

    Concerning the generator, do remember that they rate the DBs at a prescribed distance (like 7 feet or so) but they ALSO usually rate them with a 50% load or less so you may see higher noise if it's running harder. Just something to consider. I DOUBT if the noise from the generator would be a major issue either since others in their homes will likely ALSO have their own air conditioners going and windows mostly closed.
  • Suggest you have your relatives go and explain the situation to the closest neighbours and advise that it will be shut off by 'x' o'clock.
  • It should not be a problem if common sense is used. Neighborhoods like you describe are often busy with lawn mowers, trimmers, chainsaws and leaf blowers. The real thing to observe is quiet times, nothing noisy before 8-830 AM......and after 7-730 at night. if anyone complains you might have to rethink your strategy.....
  • It will be like a lawn mower running all day. Personally I would find that annoying if it's a quiet setting and everyone is enjoying the lakeside ambiance. OTOH, if it's like some party area's on lakes they may never hear it over the other noise.
