COVID-19 has caused the greatest reduction in noise pollution ever recorded in human history

The COVID-19 pandemic has taken hundreds of thousands of lives and devastated the global economically. However, there have been a few positive unintended environmental consequences created by the virus.
Reports show there has been a significant reduction in climate-change creating greenhouse gasses in the first half of 2020. A newly-released report has found that human-generated noise pollution is down by up to 50% as well.
The research published in the journal Science was led by Dr. Thomas Lecocq and Dr Koen Van Noten of the Royal Observatory of Belgium in Brussels and involved 76 authors from 66 institutions in 27 countries.
Seismologists believe this period may be the quietest since humans have been able to measure noise pollution and have dubbed it the "anthropause."
These scientists measure seismic waves to detect earthquakes and volcanic activity, but have to consider in the rumble of human activity caused by traffic, construction, and even sporting events, to get accurate information.

To assess the reduction in human-generated noise pollution, the researchers looked at 268 seismic stations around the world and found that 69% of them showed "showed significant reductions in human-caused noise."
The researchers also noticed a wave of sound reduction that began in China, then moved towards Western Europe, mirroring the progress of COVID-19 earlier this year.
"We were able to clearly link reductions in activity with lower seismic noise readings," Professor Martha Savage, a geology academic from New Zealand's Victoria University of Wellington who was involved in the study, said according to Vice.
The change in the global audio-environment revealed that human-generated noise pollution travels much further into the Earth than previously thought. A a seismometer placed 380 meters underground near Auckland, New Zealand showed that activity had been reduced by 50% during lock down.

The changes in global noise pollution due to COVID-19 highlight a growing global problem. Studies show that humans who live or work in loud environments are more susceptible to high blood pressure, heart disease and low birth weight.
"What we're doing to our soundscape is littering it. It's aural litter—acoustical litter—and, if you could see what you hear, it would look like piles and piles of McDonald's wrappers, just thrown out the window as we go driving down the road," Les Blomberg, the founder and executive director of the Noise Pollution Clearinghouse, told the New Yorker.
A study by the WHO found that noise pollution in western Europe leads to the annual loss of "at least one million healthy years of life."
Research on the effect of noise pollution on the animal kingdom is in its infancy stages but preliminary work shows it to be a threat to the survival of countless species. For example, fish larvae are able to find their homes through the sounds of coral reefs, this can be disrupted by noise pollution.
Owls and bats use acoustic signals to locate prey which can be disrupted by noise generated by human activity. The ubiquity of noise pollution has caused some species to relocate to live in quieter environments, effecting the biological richness that is vital to the ecological health of the planet.
The COVID-19 pandemic has been unquestionably devastating for humanity. But if there is a silver lining to be found in the crisis, it's that it's given us a vision of the world that is healthier for the entire animal kingdom.
Hopefully, this vision can will be taken into consideration by those in power as we rebuild the world when the virus subsides.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
