Coming Soon: "Neuromorphic" Chips
 
Mobile device developers are waiting anxiously to get their hands on "neuromorphic" chips, which are modeled on biological brains and designed to process sensory data, such as sound and images, and respond in ways not specifically programmed. MIT Technology Review calls these revolutionary chips, which wireless giant Qualcomm is demonstrating to developers, one of the 10 breakthrough technologies of 2014. Find out how these chips differ from traditional processors. Envision a smartphone that knows when you want to hear music or learns from your past voice commands not to take calls from telemarketers during dinner.

QB™2 — a Technology for Personal Quiet Zone
Silentium Ltd.
 
Recently Silentium introduced the Quiet-Bubble™ family. The idea is to capture the ambient noise of your environment, creating a quiet zone — the same as headphones, but without headphones. Quiet-Bubble™ technology reduces disturbing noise, no matter what the source!

Please contact yoel@silentium.com to schedule a demonstration in one of Silentium's show rooms.

Big Sound for Big Bucks
 
As the Absolute Sound sees it, there's no better place to sample the latest speaker technology than the Munich High End Show. This article discusses audio systems that drew the most attention, such as the $100,000 Zellaton Reference, which one reviewer says reproduces LPs and digital media with more speed, openness, and resolution than any other cone speaker. Get details on components in other speakers whose strengths include dynamic range, through-the-floor extension, and amazing style.

Fighting Back in Home Theater
 
Sony has lost much of its mojo in the mobile audio market, but the company is moving aggressively in home theater. In this review, get the particulars on the company's economical new HW-CT770 sound bar, positioned to compete with cost-conscious models from Samsung and Vizio. Among the technical pluses: three HDMI inputs, several sound presets, and an embedded gyroscope designed to trigger DSP adjustments dependent on the bar's orientation. See video for more.

Find the Right Acoustic Solution
 
Looking for acoustic or noise-reduction materials? Here's one magazine's recent roundup of 12 different choices — from composites and metal mesh panels to hardwoods and materials that score high on recyclable content. See how these materials are put to work in a variety of settings, such as churches, auditoriums, offices, and airports. An aquatic center even features an elaborate overhead sculpture made of sound-dampening melamine foam. Want more? Get this book on concert hall acoustics.

Inching Toward "Beam Me Up"
 
The technology is far from Star Trek proportions, but a team of researchers from Scotland, UK, and the U.S. has built a functioning acoustic tractor beam that can pull objects of centimeter size. In the lab, the scientists put an array of ultrasound emitters at the bottom of a tank of water and used a hollow isosceles triangular prism as the object to be pulled. Possible early applications: manipulating objects or tissue in medical procedures.

How to Tame Nuisance Noise
 
When Finnish shipbuilder Wärtsilä got complaints about noise from its engine assembly and test plant, the company turned to a software program called Actran to determine the source of the problem. After taking a series of sound measurements at various locations, engineers used Actran to create a vibro-acoustic model and simulate possible solutions for noise reduction. Get more details here, including a video featuring an acoustics expert.

Can Voice Analysis Track Mood Swings?
 
Using a smartphone app that monitors the conversations of people with bipolar disorder, University of Michigan researchers say they've detected speech patterns associated with manic and depressive episodes. The researchers are studying patients as they experience all aspects of bipolar disorder mood changes. Over time, they hope to develop software that will learn to detect the voice changes that precede the transitions to each of these states.

And the Beats Go On
 
Beats Electronics, acquired by Apple in May, has added some new wrinkles to its Solo headphones, which sold at the rate of four pairs per minute in 2013. The new Solo2 boasts a new set of drivers, tuned for a wider dynamic range — especially sharper sound at the high end. Ear cups are slightly larger and fit more snugly, providing a tight seal that keeps most noise out, while preventing music leakage.

Measuring Noise Exposure
 
This newly updated standard, now available from IHS, describes procedures for determining the occupational noise exposure in workplaces. It provides procedures for measuring exposure from all types of noise: continuous, tonal, and impulsive noise. This standard can also be used to measure noise from non-occupational sources, such as music players, radios, and other sound reproduction devices.
