Jillian Scudder, Forbes, asks What Does The Sun Sound Like? Scudder, a Postdoctoral Research Fellow in Astrophysics, notes that a major problem with recording sounds in space is that “there’s no atmosphere for sound waves to travel through, so any pressure waves an object may be producing will be instantly silenced without a medium to compress.” But, she adds, “there are other ways of recording information which can be translated into a sound; the easiest one is vibrations.” Enter sonification,”a booming area of data manipulation — it’s another face of the data visualization scene; instead of presenting the information visually, you can code it audibly, and listen to it over time.”

and it’s not for a good reason. Claire Asher, BBC, reports on how climate change and animal extinctions have altered the way our world sounds. Asher writes that human activity is changing our natural soundscape irreversibly:
And it is more than our oceans that are affected. Asher notes that “natural spaces are now polluted with human-made noises. As we change forests into farms and drive species to extinction, we are fundamentally changing how our world sounds.”

Plants Have an “Ear” for Music. Matthew Sedacca, Nautilus, writes about Dan Carlson, Sr., who, after his experience in the Korean demilitarized zone in the 1960s, dedicated himself to “increase plant growth and help reduce, or even eliminate, world hunger.” Carlson studied at the University of Minnesota, trying to learn everything he could about how plants grow. What he discovered was interesting:
Years later, Carlson believed he found part of his answer. He maintained that “green music”—sounds akin to, or recorded from, those found in nature, like birds singing or crickets stridulating—possesses frequencies that boost plant growth and yield rates. He claimed that when exposed to synthesized birdsong, a plant’s stomata—the mouth-like pores on the underside of leaves that absorb water and nutrients and expel oxygen—widen. Before he died in 2012, he listed growing a Purple Passion (Gynura aurantiaca)—a houseplant that usually grows up to a foot—1,300 feet high to the sound of green music as one of his lifetime achievements. It earned him a Guinness World Record.
Yes, it sounds kind of nutty, and some people in the past relied on pseudoscience, but today “plant bioacoustics is a growing field of interest in science.” In fact, in “a recent study published in Scientific Reports, a team of researchers from Yeungnam University in Gyeongsan, South Korea, found, just as Carlson did over 30 years ago, that “green music” can cause plants to undergo biological transformations.”

[A] term used to describe a sensory experience characterized by a pleasant tingling sensation in the head and scalp, which can be triggered by sounds like whispering or brushing, and visual stimulus like painting or drawing. On YouTube, the phenomenon inspired the creation of “whisperer” videos, in which people attempt to trigger the viewer’s ASMR by speaking in a soft voice and making various sounds with inanimate objects.
Personally, we thought the ASMR would make an excellent white noise loop. Enjoy!
This is what a frozen lake sounds like.Alessandra Potenza, The Verge, writes about “one of the coolest sounds you can hear. A frozen lake that looks like it’s been stopped in time, but in fact keeps shifting and moaning sounding like a Star Wars blaster.” Sadly, she didn’t have equipment to record the sound, but she found a good example online:
