It has also launched to customers in and around Darlington in the north of England.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Smaller drone delivery services are popping up too: in some US cities, customers can order flying treats from their local pizza joint or ice cream parlour.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Even in cities where noise is already a steady part of life, the sound of drones seems to irk in a particular way.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">While the steady passing of traffic might blend into the background, the sudden whine of a drone&#8217;s rotors can pierce the everyday hum.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">The sound tends to be &#8220;particularly noticeable, even when overall sound levels are relatively low,&#8221; says Antonio Torija Martinez, professor in acoustic engineering and psychoacoustics at the University of Salford.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Unlike planes, drones operate at low altitudes and may fly directly over residential areas.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;They can expose communities that have not previously experienced significant aircraft noise, and who may therefore be more sensitive to changes in their local soundscape,&#8221; says Torija Martinez.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">He points to research showing that people respond strongly to a noise when they consider the source to be &#8220;novel, intrusive or frequent&#8221;. People who benefit from a drone delivery service, for example, may be less bothered by the noise.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">However, complaints about the sound of drones are likely to grow, he warns: &#8220;At the moment we are seeing some of these problems localised in some areas, but\u2026 as the drone sector expands, more and more of these complaints will happen.&#8221;<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">In the US, the Federal Aviation Administration (FAA) regulates commercial drones, but it has come under fire for allowing noisy drone delivery operations. The FAA says operators and local community leaders have primary responsibility for addressing any community concerns.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div data-block=\"image\" class=\"ssrcss-l7emlr-ComponentWrapper e1aon0op1\">\n<div class=\"ssrcss-126h8e-Spacer e1aon0op0\">\n<div data-testid=\"image\" class=\"ssrcss-1uy5kw5-FullWidthWrapper ep2nwvo1\">\n<figure class=\"ssrcss-hc6arm-StyledFigure e34k3c22\">\n<div class=\"ssrcss-ab5fd8-StyledFigureContainer e34k3c21\"><span class=\"ssrcss-1fvocx3-Placeholder etlorgc0\"><picture><source srcset=\"https:\/\/ichef.bbci.co.uk\/ace\/standard\/240\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 240w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/320\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 320w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/480\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 480w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/624\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 624w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/800\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 800w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/976\/cpsprodpb\/47d8\/live\/a8c659b0-c7b7-11f1-a64c-550be9e3c66b.jpg.webp 976w\" type=\"image\/webp\"><img decoding=\"async\" alt=\"A greenjets drone has a blended wing and fuselage with two enclosed motors on the upper side.

It has also helped conservationists in Africa, who are seeking to track poachers from above without being detected.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Battlefield drone operators also have good reason to keep the noise down, to avoid alerting the enemy of the approach of their unmanned vehicles.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;There are some efforts to reduce the sound of drones. The US Special Forces are interested, at an experimental stage,&#8221; says Robert Tollast, a research fellow at Whitehall think tank The Royal United Services Institute (RUSI).<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">But he stresses that drone speed, rather than stealthiness, tends to come first for larger drones used in the war between Russia and Ukraine. &#8220;Make it faster, not less quiet, seems to be the approach,&#8221; says Tollast.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div data-block=\"image\" class=\"ssrcss-l7emlr-ComponentWrapper e1aon0op1\">\n<div class=\"ssrcss-126h8e-Spacer e1aon0op0\">\n<div data-testid=\"image\" class=\"ssrcss-1uy5kw5-FullWidthWrapper ep2nwvo1\">\n<figure class=\"ssrcss-hc6arm-StyledFigure e34k3c22\">\n<div class=\"ssrcss-ab5fd8-StyledFigureContainer e34k3c21\"><span class=\"ssrcss-1nabomw-Placeholder etlorgc0\"><picture><source srcset=\"https:\/\/ichef.bbci.co.uk\/ace\/standard\/240\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 240w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/320\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 320w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/480\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 480w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/624\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 624w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/800\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 800w, https:\/\/ichef.bbci.co.uk\/ace\/standard\/976\/cpsprodpb\/7408\/live\/707b6180-c7b8-11f1-9a39-31b474234113.jpg.webp 976w\" type=\"image\/webp\"><img decoding=\"async\" alt=\"Sharrow Engineering boat propellers underwater.

Specifically, it was the tips of the blades that he realised were creating the noise as they swiped through the air.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;I asked myself a very simple question, what would a tipless propeller look like and how would it function?&#8221;<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">The result was to create a propeller with twisted loop-shaped blades with no points.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">It turned out it was easier to test his propeller in water than it was to repeatedly fly a drone, which led Sharrow to initially develop a less noisy boat propeller. Now, however, his company, Sharrow Engineering, is focusing on developing &#8220;ultra-quiet&#8221; drone rotors.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;We have validated that the technology works in drone applications and that it is dramatically quieter,&#8221; says Sharrow.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Companies at the forefront of drone deliveries say they are also working to reduce the noise of their fleets. A spokesperson for Amazon says it has made &#8220;measurable sound improvements&#8221; to its drones and its latest designs use custom-designed propellers &#8220;that produce almost half the perceived sound of the prior generation, with a milder tone&#8221;.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Drone maker Wing, which provides its vehicles for Walmart deliveries, says its propellers are designed to minimise noise. It also varies its flight paths to prevent repeated overflights over any single home or neighbourhood.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">For Schmidt, fed up with the noise of drones, the only truly satisfactory solution would be to halt drone deliveries in her area. &#8220;I would like them to completely stop until they figure out how their services stop being a nuisance,&#8221; she says.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div data-block=\"topicList\" class=\"ssrcss-vxwoax-ComponentWrapper e1aon0op1\">\n<div class=\"ssrcss-tcr9z1-Spacer
