Whisper Aeroemerged from stealtha lilliputian over two years agowith a straightforward ( if challenging ) plan : to radically reduce interference emissions from next - gen aircraft with a never - been - done - before electrical thruster .
But accord to Whisper COO Ian Villa , from the very beginning , the party was thinking more exuberantly . The inauguration was found by Villa and CEO Mark Moore , both former executives at Uber ’s aeriform ridesharing labor Elevate . early on on , the two founding father had a suspicion that the electrical propulsor could be scale down for production outside the aviation diligence .
Like , say , lawn care .
“ If we showed you our seed round deck , we had a leafage cetacean in it , ” Villa read in a recent consultation . “ We ’ve always have it off leaf blowers would be on the path . The real question was when . ”
The answer to that motion is “ now . ” Today , Whisper has unveil “ Whisper Drive , ” a scaled - down galvanic ducted lover that can be integrated into leaf blower , commercial radio-controlled aircraft or other consumer products . The society read that a Whisper driving - enabled leaf blower can be up to 40x quieter at 50 foundation than its competitors , efficaciously turning a neighborhood nuisance into a barely perceptible stillness .
The result is a leaf blower that emit just 45 decibel of randomness at 50 substructure and full throttle . In comparison , gas foliage cetacean emit between 70 - 90 decibels of sound at the same condition , while the quietest electric leaf electric fan on the market emit around 57 - 59 decibels .

rustling engineers set forth playing around with the concept for a subdued leaf blower after the company had already developed and flown an early - multiplication 10 - Ezra Loomis Pound thruster for a protester drone . Using some 3D - printed theatrical role and spare stamp battery , they modified the propulsor into a leaf cetacean MVP .
“ We were blown off , ” Villa said , likely not think to make such a good pun . “ It was just insane how magically quiet it was . We looked at the numbers and we state , ‘ Okay , we get it on how much thrust this produce . ’ [ … ] And it dawn on us , not only was it quiet , but it has to be moving more air than an equivalent handheld leaf electric fan . ”
rustling set up the very same examination fishing rig that outdoor magnate equipment vendors use , so they ’ve been able to do direct comparisons between a Whisper Drive - enabled blower and blower uncommitted for purchase . Whisper engineers have also been able-bodied to subjugate the blower to airmanship - grade testing , which has allowed them to measure stab and randomness to a highly accurate degree , Villa say .
While the company was capable to prove tremendous disturbance reduction with just a prototype , it was n’t consumer - friendly in terms of cost , so Whisper had to think seriously about how to descale manufacturing up and drive cost down .
“ The leaf cetacean mammal was a way to tackle that in a ware - aligned way , where we can perform these experiment , come up with something that we knew the public want , but then also solve [ the question of ] how are we move to make these pusher cheap enough for commercial drones . To us it was a win - win . ”
The large style the company ’s been able to add costs down is via an injection molding technique using low - cost materials . The most expensive part of the leaf blower is the bombardment , and Villa said that Whisper Drive ’s improved efficiency will generate longer draw sentence and decreased barrage fire weight .
Leaf electric fan may seem comparatively low technical school — blow strain , move leaves — but this is exactly why they ’re such a prime product to target , Whisper state . More and more community have enact usage restrictions on leafage blower due to the noise , which is bad news program for lawncare workers , especially those that live in red-hot region and may not be able to start piece of work during the nerveless parts of the solar day . Depending on use , workers may also be required under federal law to wear auditory modality trade protection . Whisper thrust - enabled leaf blower would make noise restriction irrelevant and hearing auspices unneeded .
To be clear , Whisper is not build a foliage cetacean ( just the propulsor ) , but the company is already in talks with a few possible partners to convey the extremist - quiet blower to the market place . Villa say the company ’s goal is to lock in a partnership toward the death of this twelvemonth or outset of next year , so that the blower can be available for leverage by 2025 or sooner .
The new product is part of Whisper ’s broader strategy to bring in early gross and diversify its portfolio — go after mellow - jabbing defense and commercial-grade aviation on one close , to lower - knife thrust products like leaf blowers or commercial-grade drone on the other .
“ We have a significant percentage of the team work on high thrust , we also have a meaning dowery of the squad are working on low poke , ” Villa say . “ Really , they ’re interactive . ”
A quieter , more effective and affordable galvanizing foliage blower may even be the final jog in turn the lawncare industriousness — which has historically relied on gun - powered machinery — greener . While the share of the electric lawn equipment market has been rapidly growing , especially amongst private consumer , it ’s still not the absolute majority .
“ A luck of landscaper have already gotten on the bandwagon , ” Villa said . “ When you calculate at the clam and await at the economics of it , just like how electric aviation has favorable economics to some alternatives , the same affair is true in the landscaping space . The difficulty is , you have these favorable political economy , but there ’s limitations . To break through those limitations in term of run metre , in terms of performance , in term of noise , you need enabling applied science . ”
“ This Whisper Drive that we ’re able to apply in a foliage blower software , is that key enabler . ”
