For most of human history, night arrived as a planetary certainty. Darkness spread across landscapes, and the sky revealed thousands of stars. Today, that sky is disappearing. Artificial light spills upward from cities, scattering through the atmosphere and turning night into a permanent haze. Research mapping global sky brightness shows that more than 80 percent of humanity now lives under light-polluted skies, and the Milky Way has vanished from view for over a third of the world's population.

All of the headphones studied contained hazardous substances, including bisphenols, phthalates, and flame retardants. The study notes that these findings do not pose a threat to people using these headphones in the immediate future, but goes on to observe that repeated exposure to the substances mentioned above pose a long-term risk to public health.

The design of classrooms, childcare facilities, community centers, and public spaces directly shapes how sound is perceived, how communication unfolds, and how inclusion is experienced. Acoustics, spatial configuration, lighting strategies, and material choices can either reinforce barriers to participation or foster environments that support diverse auditory experiences.

I didn't want to get hearing devices because, to me, there was a horrible stigma. People who wore hearing aids were doddering. They didn't listen, they said, 'what, what,' over and over. Worse, the hearing aid would make this squealing sound. I worried that it was the beginning of the end of me.

I'm very sensitive to sound, so the smallest noises can be distracting. Silence is sometimes loud for me. After the diagnosis, Sussman's parents switched him to a school that specialized in helping students with learning differences. His mom also started playing brown noise to help him relax or fall asleep, after she read that low-frequency (lo-fi), deep rumbling sounds-like heavy machinery or strong rainfall-can soothe those with ADHD.

Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.

Last week, the hotel's leaseholder, Trinity Hospitality, sought a court injunction "to reduce excessive noise transfer from Yamamori Izakaya into the hotel". It sparked a protest outside the hotel on Monday by protesters concerned about a drop in the number of late-night venues. The Hoxton Hotel, which neighbours Yamamori Izakaya, a Japanese restaurant that holds music events, claims it has been forced to close around a quarter of its rooms because of "numerous guest complaints about late-night, low-frequency music noise and vibration".

When professionals talk about how to remove background noise from video, they are really talking about improving the audio track of a video so the speaker's voice is clearer, more consistent, and easier to understand. Background noise refers to any unwanted sound that competes with the main voice, like air conditioning hum, office chatter, keyboard typing, traffic, or the low hiss created by recording equipment and compression. In video production, background noise removal is about reducing distractions so the listener can focus on the message.

But what you have the right to do is not always the action that will lead to the most happiness for you. In fact, if you insist upon escalating before exploring a gentler approach, you will often make things worse. So your wife isn't entirely full of it. Tense relationships with neighbors really do make a lot of people miserable, and it makes sense that she'd want to avoid pissing off people who live within shouting distance and are apparently pretty combative.

The rhythm of open offices is great until you need to concentrate or take a video call. The energy becomes noise, conversations drift across the floor, and people end up camping in meeting rooms or wearing noise-cancelling headphones all day. The ad hoc solutions never quite work, and what is missing is a middle ground, something more substantial than a desk but less isolating than a full pod.

When Matt Hillier was in his 20s, he went camping with a friend who was a nurse. In the morning she told him she had been shocked by the snoring coming from his tent. She basically said, For a 25-year-old non-smoker who's quite skinny, you snore pretty loudly,' says Hiller, now 32. The Guardian's journalism is independent.

Remember the pocket archaeology of untangling your headphones every single time you pulled them out? That split second of dread when you'd fish them from your bag only to discover they'd somehow tied themselves into impossible knots? Designer Aleš Boem remembers. But instead of trying to solve that universal frustration, he's immortalized it. His project, Tangled Headphones for print, takes that chaotic mess of wires we all spent years battling and transforms it into something worth looking at.

In the fast-paced race to load AI into every smartphone, laptop, tablet, and earbud, the flashiest AI-powered features usually receive the most attention. When your earbuds use AI to perform real-time translation services or allow hands-free access to a gen AI chatbot, you'll know. There's another way your earbuds use AI that isn't as exciting to talk about, but when it's done well, it's incredibly valuable: AI-powered adaptive noise cancellation.

I tend to find them underwhelming because overall sound quality is subpar compared to the more "traditional" in-ear models. Any promise of noise reduction, or a far-fetched claim of noise cancellation, usually doesn't hold true. The first time I used the Shokz OpenFit Pro ($249.95) I was immediately met with better audio performance than I'd just experienced on Sony's new LinkBuds Clip and noise reduction technology that actually lessened some distractions.

We are seeing that there is a huge move towards voice as a new interface that a lot of folks are adopting. You can do much more with voice in a natural way than with a keyboard. However, we saw that voice is rarely an interface people use when others are around. So that using our noise isolation model, we will give consumers a way to experience a voice interface in the form of our earbuds,
