Sound

Between 2 and 4% of the world's population report hearing a mysterious buzzing or vibration. It's called The Hum, and for decades, scientists, engineers, and ordinary people have been trying to figure out what it is.

A novel way to brew coffee without boiling water or high pressure harnesses the power of sound waves, slashing time and energy.

Pupil dilation and subtle facial changes in response to sound can reveal how severe tinnitus is. Through this, researchers have discovered a new way to objectively gauge how bad the condition is, more accurately diagnosing tinnitus and treating it.

Nobody likes being carsick, seasick or airsick, but what can you do to keep from getting that way? Well, according to a new study, simply listening to an audio tone for one minute might be all it takes to stop you from losing your lunch.

You may not think of fish as being noisy, but they can actually be a pretty vocal bunch. A new AI system is able to quickly identify specific fish calls within general reef noise, allowing scientists to better track local populations.

You might not hear it, but rodents are known to speak to each other in voices so high-pitched that human ears can’t pick them up. Now scientists have found that these vocalizations might have a second purpose – they help them smell better.

It turns out that blasting people with shockwaves during open-heart surgery is a really good idea. That's what researchers found who used the technique to reactivate heart cells and improve the post-op lives of patients in a groundbreaking study.

Scientists have discovered that audio recordings of healthy coral reefs may help attract free-swimming coral larvae to damaged ones. The finding could be a major step toward preserving the world's coral reefs.

If someone you know has gone through chemotherapy, you might be familiar with the side effect 'chemo brain.' Scientists have now demonstrated a simple way to protect brain cells from damage using flashing lights and sounds at a certain frequency.

A tiny, newly-discovered minnow has measured louder than gunshots, jet engines or most competition-grade car stereos on the decibel scale – which raises the question: how on Earth was it not discovered earlier? It hasn't exactly been discreet.

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

A study has found that playing a soundscape to a common, plant-promoting fungus found in soil caused it to grow more rapidly than fungi that weren’t exposed to sound. The novel ‘eco-acoustic’ approach has the potential to restore damaged ecosystems.
