This Sound-Tracking System Is Like a 'Smoke Detector for Noise'

You may expect your neighbors to get a little noisy now and then (like when they're cheering on a football game or hammering their walls), but there’s a difference between the occasional disturbance and a racket that keeps you up every night. A sound-detecting system called NoiseAware was designed to distinguish between the two.

NoiseAware bills itself as “a smoke detector for noise.” According to Co.Design, the Wi-Fi enabled decibel sensors are plugged into walls where they listen for sound trends that fall outside the norm. Sound caused by something accidental, like a plate falling to the floor, for instance, gets ignored. But if NoiseAware senses a rowdy party or a prolonged screaming match happening in the space, it will alert its owner via text so they can handle it from there.

The product is meant for landlords who want a way to curb their tenants' disruptive behavior when they’re not on the property, but it can also be used by Airbnb hosts or even parents who want to keep tabs on their kids when they’re home alone. NoiseAware tracks general noise patterns over time without recording actual sound, which means the content of private conversations is kept private. Property owners can shop systems online—and even if you don't own your home, you can always try suggesting it to your landlord to deter noisy neighbors.

The World’s First 3D-Printed Opera Set Is Coming to Rome

In October, the Opera Theater in Rome will become the first theater to play host to a 3D-printed set in one of its operas. The theater’s performance of the 19th-century opera Fra Diavolo by French composer Daniel Auber, opening on October 8, will feature set pieces printed by the Italian 3D-printing company WASP, as TREND HUNTER reports.

Set designers have been using 3D printers to make small-scale set models for years, but WASP says this seems to be the first full 3D-printed set. (The company is also building a 3D-printed town elsewhere in Italy, to give you a sense of its ambitions for its technology.)

The Fra Diavolo set consists of what looks like two warped historic buildings, which WASP likens to a Dalí painting. These buildings are made of 223 smaller pieces. It took five printers working full-time for three months to complete the job. The pieces were sent to Rome in mid-July in preparation for the opera.

Recently, 3D printing is taking over everything from housing construction to breakfast. If you can make an office building with a printer, why not a theater set? (Though it should be noted that the labor unions that represent scenic artists might disagree.)

A Simple Way to Charge Your iPhone in 5 Minutes

Spotting the “low battery” notification on your phone is usually followed by a frantic search for an outlet and further stress over the fact that you may not have time for a full charge. On iPhones, plugging your device into the wall for five minutes might result in only a modest increase of about three percent or so. But this tip from Business Insider Tech may allow you to squeeze out a little more juice.

The trick? Before charging, put your phone in Airplane Mode so that you reduce the number of energy-sucking tasks (signal searching, fielding incoming communications) your device will try and perform.

Next, take the cover off if you have one (the phone might be generating extra heat as a result). Finally, try to use an iPad adapter, which has demonstrated a faster rate of charging than the adapter that comes with your iPhone.

Do that and you’ll likely double your battery boost, from about three to six percent. It may not sound like much, but that little bit of extra juice might keep you connected until you’re able to plug it in for a full charge.
