The "Hands Free" Challenge

The 'Hands Free' Challenge With the onslaught of legislation to ban cell phone use in moving vehicles comes the task of designing wireless headsets and hands-free devices that function optimally in the challenging noisy environment of the automobile. Fortunately, designers are rising to the occasion by developing devices that utilize the latest advanced audio processing.

Because portable electronic devices are approaching ever smaller form factors, the ability to deliver high-quality sound, suppress noise, and minimize distortion is no easy undertaking considering all-important maximum battery life. This recent EE Times Asia article examines the approaches being utilized by major manufacturers. [A short registration may be required.]

MEMS Mikes Sport Best SNR

MEMS Mikes Sport Best SNR A new family of microphones provides the highest signal-to-noise ratio in the industry: 61-dB A-weighted, compared to today's best cell phone performance at 55 dB. The omnidirectional mikes — with either analog or digital output — also lay claim to the flattest frequency response in the industry from 100 Hz to 15 kHz.

Boost Wireless Range with Antenna, Not Amp

Boost Wireless Range with Antenna, Not Amp Slated for 2.4 GHz wireless applications, TI reference designs for low-power RF ICs are now equipped with an AirWire™ antenna to boost range almost two-fold or halve power. The integrated high-gain antenna is a resonant slot PCB type that delivers a 3-5 dBi gain, along with band pass filtering to minimize noise.

New Physics Cuts Aircraft Noise

New Physics Cuts Aircraft Noise Designed to reduce aircraft noise by up to 30%, microchanneled materials made of metallic nanotubes cause acoustic waves to dissipate in the channels rather then resonate. This broadband acoustic absorption method reduces sound regardless of frequency. Light, strong, and heat-resistant, a prototype microhoneycomb material (shown) is made from a nickel superalloy.

These Props Are "Tops"

These Props Are 'Tops' When it comes to noise reduction and vibration optimization, these eight-blade composite props are tops. Retrofitted to replace four-blade metal counterparts, the star-like configurations also boost performance and reliability, while delivering increased thrust and fuel economy. In November, the retrofitted LC-130 is scheduled to fly into Antarctica to prove its mettle in ice and snow.

High Temperature Acoustic
Measurement System

PCB Piezotronics Inc.

High Temperature Acoustic Measurement System The Automotive Sensors division of PCB Piezotronics has announced release of the industry's first IEC-compliant high temperature acoustic measurement system, Model 378B02, a combined prepolarized ICP® microphone and preamplifier, which allows for high temperature automotive acoustic testing to +120° C, and eliminates the need for high-priced probe microphones.

ARIS — Acoustic Resonance
Inspection System

Resonic NDT Systems

ARIS — Acoustic Resonance Inspection System Resonic NDT Systems is proud to announce the patented ARIS high speed, high resolution test instrument for inspection for defects, porosity, hardness, plating integrity, and verification of size and/or thickness of metals under test using the acoustical wave properties of materials to detect anomalies on the surface and any level below the surface.

Why Use DSPs?

Why Use DSPs? The flexibility of today's digital signal processors (DSPs) allows them to do some tasks better than analog circuitry, and they are often the better alternative when it comes to cost concerns and complex circuits. Integrated DSP chips can feature more than one core, incorporate I/Os, memory subsystems, and lots more. To learn more about what the latest DSP chips can do, review this recent Electronic Design article.

Out of This World DSPs

Out of This World DSPs Advanced DSP (digital signal processing) functionality augments Actel's radiation-tolerant FPGAs (field programmable gate arrays) for deployment in space. The single-chip solution provides signal processing up to 8 billion multiplications/sec from -55 to 125 C. Applications include communications, data handling, imaging, and radar.

Mobile Broadband Good to Go in Laptops

Mobile Broadband Good to Go in Laptops Later this year, users who buy new laptops and notebooks will be able to "surf right out of the box" thanks to Mobile BroadbandSM. The GSM Association, which leads the industry group — including Microsoft, Dell, Lenovo, Toshiba, and many more — said late last month that the computers will use GSM networks in 91 countries to connect to the Internet, hopefully in time for Christmas shopping.

Mobile Searching Hits the Fast Track

Mobile Searching Hits the Fast Track Searching from mobile phones is becoming more popular than ever. In fact, says comScore, growth is downright explosive — up 68% in the U.S. and 38% in Europe compared to last year. As far as search providers go, Google is still in the lead with a 60% market share, followed by Yahoo with 35%. Installing Yahoo oneSearch on select phones allows users to conduct voice-enabled searches.

Overall Acoustic Level
OROS Inc.

Overall Acoustic Level The OROS Overall Acoustic is an optional NVGate plug-in for all OROS 3-Series Analyzers. With an OROS 3-Series you get a multi-channel analyzer, so why not turn your unit into a true multi-channel sound level meter. The OVA plug-in extends the analyzer capabilities to a comprehensive acoustic measurement system.

High Intensity Acoustic Sensor, Model 2180C
Dytran Instruments, Inc.

High Intensity Acoustic Sensor, Model 2180C The Dytran pressure sensor model 2180C is a high intensity acoustic sensor ideal for measurements involving gas turbine combustor dynamics. This all-welded stainless steel sensor can monitor pulsations, turbulence, a noise in hydraulic and pneumatic systems, as well as detect pressure fluctuations in exhaust systems, compressors, turbines, pumps, and pipelines.

Engineering Careers = f (U.S. Economy)?

Engineering Careers = f (U.S. Economy)? With the U.S. economy in arguably its worst shape ever in recent history, most engineers have the smarts to be concerned that their jobs could be headed for oblivion. In embedded.com, Jack Ganssle addresses some job outlook issues and identifies some contradictions. For instance, "tech is the place to be" but Silicon Valley unemployment hit a four-year high in August. Is the once rosy outlook for engineering jobs waning?

Diversions . . .
Noisier Oceans

Noisier Oceans The oceans are not only getting warmer, but also more acidic from CO2 in the atmosphere. As a result of this pH change, less sound is absorbed. Scientists predict that a 0.3 drop in pH by the end of this century would result in a 40% drop in sound absorption below 1 kHz — hence more noise. It remains to be seen how this noise will affect low-frequency whale communications and military operations.
