Modern sound mixing has contributed to audiences needing subtitles

The 'second screen' effect has realigned the writing for Netflix's original shows

As more subscribers put Netflix on in the background, the company has encouraged more expositional dialogue in its original scripts. Filmmaker Justine Bateman claims the streamer doesn't "want anything on your show to distract [viewers] from their primary screen."

Authoritarian regimes sometimes used film dubbing to censor ideas

Dubbing rose in popularity in the early 20th century because of relatively low literacy rates, which made subtitles impractical. Totalitarian regimes—including Mussolini's Italy, Franco's Spain, and Hitler's Germany—used dubbing to remove or alter unflattering or countercultural dialogue.

Microphone technology made crooning possible

Before the electric microphone, vocalists needed to project to have their voices captured. The new technology, however, made softer, more intimate singing possible, leading to a new style of singing that took off in the late 1920s, with "crooners" becoming some of the first American pop stars.

Noise-canceling headphones cancel out environmental sounds with sound of its own

If sound waves are perfectly out of sync, they can undergo destructive interference, canceling each other out. A microphone in noise-canceling headphones picks up external sounds, and an out-of-sync version is emitted to cancel them out in your ears.

Visualizing shifts in emotional performance in film

Computational scientists were curious: has the intensity of emotional expression in films changed over the decades? Using their sophisticated analytical models, the researchers discovered actors' emotional performance has declined in intensity over time. They believe the close-up shots common in contemporary film-making allows actors to be more subtle in their performance. Check out the main takeaways and charts with this unusual study.

Supermassive black holes create pressure waves, detectable as extremely low sounds

Space is largely silent because it lacks a medium for sound waves. Some Mars rovers capture sounds of wind, though the sounds are too low to hear. Through sonification, astronomical data can be translated into hearable sounds for broader engagement.

How does the cocktail party effect work?

In the 1950s, British cognitive scientist Colin Cherry started to explore how we could focus our hearing on one single source, even in a noisy environment. This video animation explains the phenomenon known as the cocktail effect and how selective hearing works. Discover how our brain is on the lookout for important or personally relevant information, even as we are occupied in other discussions.

People with tinnitus should avoid silence—sound-rich environments distract the brain

A cochlear implant stimulates parts of the cochlea directly, with limited pitch and timbre capabilities

People with these devices have to learn or relearn how to train their brains to interpret nerve signals as sound. The range of the type of sounds that the brain can distinguish with a cochlear implant is limited and consequently it's difficult to understand a tonal language or distinguish individual speakers in a crowd.

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.

'Silent' fireworks have gained more interest in recent years as a quieter celebratory option.

'Silent' fireworks have gained more interest in recent years as a quieter celebratory option

Though not really silent, the displays are quieter than traditional fireworks. They may offer an attractive alternative for people who have sensory sensitivities or for pet owners. The sound from these options can be less loud than standard fireworks due to changes in chemical composition and the inclusion of a smaller lift charge that doesn't carry the fireworks as high into the air, reducing the initial bang.

Why you may hate the sound of your voice

It's a relatively common experience to cringe while listening to a recording of your own voice. This Popular Science article offers physiological explanations for the discrepancy between what we hear when we speak versus what others hear. The piece also expands on the psychology behind this discontent, and how our voices influence our self-perception and social interactions.

Movie trailers changed after the king of voice-overs died

Don LaFontaine, known in the film industry as "Thunder Throat," provided voice-over for over 5,000 film trailers. After he died in 2008, the trailer formula changed, with most preferring to lean into dialogue from the film.

One podcast professional believes the format needs a new name

In the past few years, the podcast has moved from a purely audio-driven medium to one that doesn’t appear all that different from a television talkshow. Audio engineer Dennis Funk proposes renaming the classic podcast—an artful audio documentary—to distinguish it from the junk posing as the genuine article.

Breaking down the music theory of Hitchcock's 'Psycho'

One of the defining features of Hitchcock’s film “Psycho” (1960) is the music, especially the sounds you hear during some particularly grisly scenes. This analysis from The Music Professor analyzes how that music complements the film, highlighting the way strings match the intensity of the film’s screenplay and black-and-white cinematography.

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.

It's not just anecdotal: Current students struggle to read longer texts and report lower reading levels for enjoyment than past generations. This brief explainer from the Chronicle of Higher Education diagnoses some of the possible causes (increased screen time and learning loss during the COVID-19 pandemic among them) along with how some educators are trying to correct the problem.

Cells modify their internal spacing to improve biochemical reaction efficiencies

Studies involving microscopy and genetic engineering tools in yeast and human cells show ribosomes act as crowding agents—much like packing peanuts—and their concentrations are actively tuned to alter the rate of cellular functions. However, these concentrations and cell crowding levels vary across different tissues and cell types.
