Drum shields—barriers that drummers are often seen playing behind—help prevent drums from being picked up by other onstage microphones, thereby improving audio mix quality.

Within an anechoic chamber, all surfaces are covered with specialized materials that prevent wave reflection, helping prevent sound from echoing in the space.

The most popular drum sound of the 1980s was discovered by accident

You know it when you hear it: the distinct snare drum of songs like Phil Collins' "In the Air Tonight" or Bruce Springsteen's "Born in the USA." It's called "gated reverb," and it's something most people associate, for better or worse, with the sound of the '80s. This Vox explainer breaks down how it was discovered by accident, thanks to a microphone typically used for communication that picked up additional sounds.

The trend of onstage mishaps

In the past few years, performers have seen a rise in onstage accidents. While artists are doing their jobs, they face risks of dangerous falls, flying objects, and audience aggression. This article aims to explain why this trend may be occurring and emphasizes the importance of concert-going etiquette and adequate security.

Faraday cages protect enclosed objects by redirecting electrical currents

Constructed from conductive materials, the cage allows electrons to distribute themselves evenly throughout its surface and travel to ground, keeping the interior neutrally charged and preventing any internal electricity. The same principle blocks electromagnetic waves by redirecting the electric field component, preventing telecommunication signals from entering the apparatus.

Stonehenge may have functioned as an echo chamber designed to keep ceremonies secret from outsiders.

Acoustics researcher Trevor Cox discovered that Stonehenge acts like a concert hall, reflecting and amplifying sound. This video shows Cox demonstrating the effect using a scale model inside a soundproof studio.

NASCAR’s SAFER barriers help reduce tragedies at races

Following the death of Dale Earnhardt Sr. in 2001, NASCAR changed its culture to be safety-first. Part of its changes were to install barriers along tracks that would help absorb the majority of g-forces in a crash. This Daily Downforce article walks through the history of the SAFER barriers, why NASCAR originally chose concrete, and how much of the tracks are covered today.

See what loud noises do to inner ear hair cells

This animation illustrates how louder music can affect inner ear hair cells. Damage to these cells is generally considered permanent. Hearing protection like ear plugs can reduce the level of sound entering into the ear and help protect those cells.

In television and film, certain sounds, such as dialogue, may be difficult to understand due to sound mixing, device limitations, and technological advancements that have collectively reduced clarity.

Interacting sound waves can create regions where the pressure from each wave combines, allowing objects to levitate in place against gravity or be manipulated for touch-free construction.

How hearing protection became cool

In recent years, the WHO shared research findings that over 1 billion teens and young people face risks of hearing loss due to unsafe listening practices. While earplugs used to hold a reputation for being uncool, this article explores how awareness has led to more people fashioning different types of hearing protection. Explore the growing trend of earplugs at raves, concerts, and other loud events.

The Grateful Dead pioneered a massive 3-story, 75-ton, 600-speaker sound system that revolutionized live audio in the early 1970s.

Mel Brooks said that learning how to drum as a kid taught him important rules about comedy, including how to structure a joke.

Objects that move faster than the speed of sound—Mach 1—create shockwaves called sonic booms by building up and forcing sound waves to combine as they lag behind the object.

A 19-month-old boy went viral for his natural drumming skills

A mother gifted her husband a drum set for Christmas, but was surprised to find their young child take a liking to the instrument. The musician couple noticed that over time the young boy taught himself proper form and how to keep up with the beat of the music. TikToks they filmed of their son went viral and amassed millions of views.

Acoustic Vehicle Alerting Systems provide motor sounds in electric vehicles

Since 2019, various global standards have set requirements for these systems, which seek to mimic combustion-engine sounds by meeting specific sonic criteria, including sound pressure, frequency, and pitch. Sound engineers design these systems to meet these requirements, ensuring that passers-by, particularly the blind and visually impaired, can detect the presence of a vehicle.

Noise-canceling headphones use a microphone to identify external sounds, which are then used to produce an out-of-sync version of those sounds to cancel them in your ears.

When struck, objects vibrate at unique rates called resonant frequencies, which makes tapping wood sound different from tapping metal, but providing objects with sound at their resonant frequency can cause them to shatter.

Playing music enhances the creation, storage, and retrieval of memories

Scans of the brains of individuals who play instruments have shown enhanced connectivity between multiple brain regions—visual, auditory, and motor cortices—and the corpus callosum, which connects the two brain hemispheres. These complex connections are strengthened through practice and then used in other activities that involve both logic and creativity. The brains of musicians also appear to give experiences multiple types of memory tags, such as audio, emotional, and conceptual, improving their processing.

In 1925, the Isolator was a helmet designed to combat procrastination and improve concentration by narrowing a person's field of vision, blocking environmental sounds, and providing oxygen.

Spikes of light around stars are artifacts of light bending around the mirror supports

Through diffraction, electromagnetic waves can bend around obstacles, as observed in the silver linings at the edges of clouds, where light should be blocked. Within reflecting telescopes, starlight diffracts around struts—beams holding a secondary mirror in place—and spreads perpendicular to them, creating pairs of spikes.

Watch a pyromusical display to AC/DC’s “Thunderstruck”

The same principles behind fireworks also power the types of pyrotechnic displays in some live events. Here, you can see an application of the technology in a pyromusical set to rock band AC/DC’s iconic song, “Thunderstruck.”

3D printing has made musical instruments more accessible

Violins fabricated from durable plastic, rather than being built from wood, can cost hundreds of dollars less, allowing children to try them out without financial pressure. They can be made in colors that appeal to children, sizes tailored to their bodies, and with tactile guides to help visually impaired learners.

Billie Holiday's distinctive vocal technique was aided by new microphone technology, which allowed for quieter singing.

Microchips in payment cards improve security by generating unique transaction codes

Magnetic strips store unchanging data that is easily cloned, but microchips act as miniature computers that encrypt sensitive data. They also resist fraud by creating data unique to each transaction, preventing duplication.

Q-tips can cause more problems than they solve

Swabbing the ear with a Q-tip can disrupt the ear wax that naturally protects the ear from dirt and bacteria. It can also tear the delicate skin of the ear drum, causing permanent hearing loss and constant discomfort that's similar to the symptoms of swimmer's ear. (Some users may encounter a paywall.)

A 'halo' protects drivers

After the 2015 death of driver Jules Bianchi, Formula 1 mandated that all cars include a protective barrier called a “halo.” This video breaks down how that measure saved the life of Romain Grosjean, who survived a horrific crash in 2020 at a race in Bahrain and later credited the halo as the reason for his survival.

Understanding why charged particles from the sun protect Earth from more dangerous particles

The solar wind engulfs the solar system in a protective bubble called the heliosphere, which was first theorized in the late 1950s based on studies of cosmic rays—high-energy particles traveling through space at near light speed. The heliosphere shields the solar system from much of this ionizing radiation originating elsewhere in the Milky Way.

Fish populations in the Great Barrier Reef have increased after installing waterproof speakers on the ocean floor that played recordings of sounds from healthy coral reefs.

Before he was Soundgarden's singer, Chris Cornell was the band's drummer

Cornell was the band's first drummer, but got out from behind the kit in 1985 so he could focus on vocals. That foundation, though, is what his bandmate Kim Thayil claimed gave Cornell his unique singing style. "Chris has an amazing way of writing melody around these odd time signatures that a lot of people have a tough time doing," he said. "It's very natural for Chris, though, because he was our original drummer, so he can think in those terms."

View a collection of sound animations, which depict how a source of sound waves pushes against particles to carry energy away without matter being displaced.

'Breather holes' in airplane windows help manage cabin pressure

Airplane windows have three layers of acrylic: the super durable outside layer, the inner pane which acts like a "scratch" surface, and the middle pane with the tiny hole. This bleed hole allows pressurized cabin air to be borne by the strong outer pane while preventing the inner pane from breaking.

Try out an online tone generator, which produces sounds of specific frequencies to help tune instruments, test your hearing, and generate beats by overlapping tones.

Surfer's ear, from repeated cold water exposure, leads to new bony protrusions in the ear

Frequent exposure to icy cold water, typical in surfing, can cause tiny bony growths to develop in the ear canal, informally called surfer's ear. While the exact cause for these growths is unknown, it may be the body's protective response to shield the ear drum from the cold. These protrusions can heighten the risk of swimmer's ear, lead to wax buildup, and result in hearing loss.

Light echoes are expanding shells of reflected starlight

Just as sound waves reveal the location of obstacles by reflecting off them, pulses of light emitted by stars illuminate rings of interstellar dust, giving the appearance of ejected material as the light travels outward.

Diatomite, a sedimentary rock used as a filtration material in beer, wine, swimming pool water, motor oil, and pharmaceuticals, is formed from the fossilized shells of diatoms, a type of algae.

Some animals possess sensitive hearing to help pinpoint prey and map the world

Bats and dolphins produce sound to reflect off surfaces and create a mental image of their surroundings. Owls' faces are dish-shaped to help funnel sounds to their ears, including that of mice moving along leaves or snow. Pinnipeds, such as seals and walruses, hear in both air and water.

NASA uses a specialized plasma wind tunnel to test heat shield technology

The ArcJet Complex ionizes compressed air that fires onto shields at hypersonic speeds, replicating the conditions of high-speed, planetary reentry. An enhanced facility incorporates lasers to mimic the radiant heating experienced during high-energy atmospheric traversal.
