Fast food delivery by drones is going to be so awesome

Except when it isn’t. No surprise, food delivery drones in Australia driving people mad. The problem, of course, is the high-pitched buzzing sound the drones make as they scurry around. Feilidh Dwye, WeTalkUAV.com, writes that one woman said “she would take her kids away from the house several hours a week, just to escape the noise. ‘With the windows closed, even with double glazing, you can hear the drones,'” she added.

So imagine fleets of drones large enough to deliver a couple of pizzas and a six-pack of beer and think about how horrific the constant high-pitched buzzing will be. Just because some Silicon Valley sociopath has figured out another way to make a billion providing a “service” no one needs, doesn’t mean we have to accept it. The days of moving fast and breaking things is over.

World’s worst restaurant concept?

We are going with yes, and we couldn’t care less about the food. Why? Because the owners of the Noisy Cafe have foisted on the world one of the worst “one-of-its-kind” concepts ever: they actively encourage patrons “to create meaningless noise.” It is really that awful?  Well, Prutha Bhosle, the poor soul tasked with reviewing the restaurant for Midday.com writes:

A surprise awaited us when the bill arrived. The steward brought along a sound meter. And then came the bizarre request – laugh out loud into the device to win a discount.

After hitting 119 dB (decible) with a pretend laugh, we were given a discount of nine per cent on the total bill. A customer who crosses the 110 dB mark, gets a concession. Stupid? We think so too.

Andy Simmons, The Reader’s Digest (yes, it still exists!), writes a biting but justified rant about the scourge of suburbia titled, “Why You’re the Worst Person In the World If You Use a Leaf Blower.”

I agree.

There’s sound information among the snippets of bitter humor.

He is the founding chair of The Quiet Coalition, an organization of science, health, and legal professionals concerned about the impacts of noise on health, environment, learning, productivity, and quality of life in America.

There doesn’t have to be a tech “solution” to everything

Case in point: The sun-blocking umbrella drone.  One could just carry an umbrella around, but no, a couple of tech bros came up with something spectacular:

WARNING: Lower the volume on your device!

Make that spectacularly awful. Says Sasha Lekach, Mashable, the “annoying hum and buzz renders the entire concept useless.”  And what is its intended use? Why “[i]t’s intended for golfers on sunny greenways.” Of course it is.

The umbrella drone is as likely to exist as Uber’s flying taxis.

Should appliance makers pay more attention to sound?

Oh look, an orchestra.

We would say yes, but no to singing washing machines.  While we appreciate sound artist and designer Yuri Suzuki’s desire to “‘propose ways for sound to not turn into noise but rather help enhance harmony and comfort” in our surrounds,” can we suggest that designers consider reducing the whirrs and rumbles of domestic appliances, allowing us to enjoy our homes in quiet?

Ever crack your knuckles and hear them pop?

Now researchers may finally know why. Apparently the noise is caused by microscopic bubbles when they pop. Summer Delany, PIX11, explains:

Your knuckles are surrounded by fluid, and when you stretch and move your joints, the pressure creates bubbles. When those bubbles collapse, a sound is produced.

And no, cracking your knuckles doesn’t cause arthritis, but “[c]hronic knuckle-crackers [are] more likely to have swollen hands and reduced grip strength.”


85 decibels is not a safe sound level for anyone, particularly children

It’s very frustrating to see headphones advertised as safe for children when they use the 85 decibel noise exposure standard without specifying a time limit. It shouldn’t be surprising, though, as even the National Institute on Deafness and Other Communication Disorders states, “[l]ong or repeated exposure to sound at or above 85 decibels can cause hearing loss.”

But 85 decibels is not a safe noise level without a time exposure limit. I wrote about this in the American Journal of Public Health in January 2017. This 85 A-weighted decibels (dBA) exposure standard is an occupational standard: The National Institute for Occupational Safety and Health recommends that workers get no more than 85 A-weighted decibels noise exposure, calculated for an average working life of 8 hours a day, 240 days a year, for 40 years. Even that exposure level doesn’t prevent all exposed workers from hearing loss. A-weighting reflects the frequencies heard by the human ear and A-weighting almost always lowers the sound measurement by 5-7 decibels. The decibel scale is a logarithmic scale, which means that 3 decibels more indicates a doubling of sound energy, and it is sound energy that destroys the cochlear hair cells, the basic sensory organ for hearing.

For children who may start using headphones as early as three years old, 40-years exposure to 85 decibels delivered directly to their ears via headphones means that they may be profoundly hearing impaired in their mid 40s. That’s not a good thing.

I suppose headphones with the occupational noise exposure level, A-weighted or not, as a volume limit are better than headphones without any volume limit. But
parents and grandparents would be wise to avoid getting their little darlings these unsafe headphones, or any headphones, unless they want to buy them hearing aids when they get older.

Dear god, no!

The Noise Curmudgeon alerts us to the horribly misguided marketing idea–because it must be the marketing department that’s behind this–that is the Nissan Canto. You see, electric cars tend to be quiet, so some sound must be engineered so that they can be heard by blind people listening for aural clues, other pedestrians, animals, etc.  Rather than engineering a traditional car engine sound for the Canto, Nissan has decided to be clever and will torment us with a “singing car.”  And by singing they mean making a variable high pitched annoying drone that will drive poeple mad.

Hear it for yourself:

Oh, that’s not so bad, you may be thinking. Then imagine a street filled with “singing” cars.

My god.

Subways can be quieter

In San Francisco, BART is grinding down wheels on its cars, making the ride quieter. New York City, like San Francisco, uses metal wheels on its subways, making for a screechy, ear drum-bashing experience from the platform to the car. So BART’s attempt is a step in the right direction. But….

Here’s how you make for a much better subway soundscape:

We can dream of a subway future with rubber tires. It’s possible.

What’s missing from this story about stadium noise in Atlanta?

Aaron Rodgers: It’s loud in Atlanta, whether it’s all natural or not.  How about a discussion about the dangers of stadium noise?  It’s nowhere to be found. Instead, this NBC post focuses on noise as a tactic and the stupidity of getting caught juicing natural crowd noise with fake crowd noise over the stadium speakers. To wit:

The Falcons were stripped of a fifth-round pick in the 2016 NFL draft and fined $350,000 after an investigation revealed that they had been using fake crowd noise while the opposing offense was on the field during the 2013 and 2014 seasons.

And? Were the Falcons penalized for injuring the hearing of every person in the stadium, or were they fined for violating whatever passes for sportsmanship in football?

This chest thumping over which stadium can produce the most noise–as if that’s a measure of anything good–would be merely pathetic if it weren’t so dangerous.
