For one thing, the average home owner does not have the means to pay professional fees required. But in this fifth blog in our\u00a0<a href=\"https:\/\/www.acoustics2024.org.au\">Acoustics in the Sun<\/a>\u00a0series, that exact issue inspired Michael Hayne and Richard Devereux to prepare a paper (<strong>Mitigation of Residential Air-Conditioning Condenser Noise<\/strong>) that gives practical advice to home owners\u2014no consulting fees necessary!<\/p>\n\n\n\n<p>I found this paper particular interesting and relevant because we have received more than one call for these problems, too. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Proximity and loudness<\/h3>\n\n\n\n<p class=\"has-link-color wp-elements-a39cb4703e20da872110912bd7ad1d5c\">The problem here is mostly one of unsolvable <a href=\"https:\/\/soundmask.com.au\/blog\/limitations-of-sound-masking\/\">proximity and loudness<\/a>. As the authors explained it, where air-conditioning noise has become a problem there are a few major issues that cannot be changed.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-5bc2b7cd7d566a5a6a91f4fd9242d432\">First of all, there is often very little space between houses. This means that the problem is up close and personal. When houses are packed into a neighbourhood like sardines, people tend to use their air-conditioning units more. If someone opened their window to get a passing breeze, they&#8217;ll quickly close it again because of the noise. And switch on the AC for good measure!<\/p>\n\n\n\n<p>Further, unlike pool pumps, water tank pumps, and the like, air-conditioning units need ventilation. Residents cannot just wrap them in insulation (although the authors showed us a few DIY disasters where they had!).<\/p>\n\n\n\n<p>The other practical problem is the home owner&#8217;s back pocket. By the time they&#8217;ve purchased their house, there&#8217;s little money left to pay for amelioration. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is all lost?<\/h3>\n\n\n\n<p class=\"has-link-color wp-elements-21b9f8ba946ab71271aa2f904f2a9c75\">Thankfully, no, all is not lost. While the noise standards, and everything else might be stacked against the humble residential air-conditioning unit, there are several viable solutions both before and after installation.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-076bc8ff69e244c327b8ae536a29755e\">The most important factor is specification. Specifying a residential air-conditioning unit that is the right size for the home means the unit does not have to over-work, and can minimise disruptive noise. Similarly, choosing a modern, quiet unit will reduce annoying noise emissions.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-dc6edb140a78e095964dd88874af7f59\">But what if the unit is already installed? Specially designed acoustic screens, enclosures and so on can reduce the noise. This might require an acoustic consultant, but often a phone call to engage a business specialising in acoustic treatments can suffice.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-88e1f45a78cd301e6d9920ba8b012e49\">Find the <a href=\"https:\/\/acoustics.asn.au\/conference_proceedings\/AAS2024\/papers\/p68.pdf\">full paper here<\/a>, including suggested air-conditioning units that have been tested for their quietness.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Residential air-conditioning noise shouldn&#8217;t be the number one question acoustic consultants get asked to solve.
