A limit of dB A weighted at the nearest residential boundary is common in Australia (hence the above questions about the specific zoning). --- End quote --- I agree. Over here low frequency noise pollution is getting more attention fortunately. --- End quote --- Off topic, but yet the Dutch government is working on laws to only allow hybrid central heating systems as a replacement from 2026 onward. Most of these systems use air to water heat pumps, which make noise. Imagine a "nice" vinex location or a town like Amsterdam with all the houses fitted with such units what a noise level that might bring.

Only when you need a new one you have to install a hybrid. --- End quote --- More uninformed/irrational heat pump scare mongering! Australia has limits on domestic appliance noise, 45 dB(A weighted) at the boundary. With plenty of installs being built right on the boundary the majority of new heat pumps meet the requirements so its not even an extra cost. There are legacy heaters gas/oil/heat-pump that fail that limit too, but since the rules only apply to new installations they get away with it. --- End quote --- 45dB(A) is rather loud especially if you want to sleep with the windows open. And as I wrote before: measuring in dB(A) is horribly wrong because it won't account for low frequency noise. |

Its very quiet, and the absolute maximum upper limit for new installations (most end up quieter again). People walking around their house or having their TV on is louder. |

What is its noise 1m from the source? how far away were you standing to it? Some days I can hear small birds tweeting in the park 100m away, were they loud or was the environment very quiet? When your neighbour is 170m away that sounds like a very rural/spread out area that would usually be a quiet environment to begin with. "I once heard some noise from a heat pump" does not imply cities will become noisy if heat pumps become mandatory. Like we say, there are noisy appliances, gas heaters can be equally as noisy as heat pumps. But modern noise restrictions have forced all the different heating/cooling options to be much quieter than they used to be (when they had no specific limits). |

Most big cities in hot parts of the world have air con for apartments and houses, and besides faulty units I've never thought they were all that loud while running. |
