Shure Celebrates 90 Years in Professional Audio

Fri, 24 Apr 2015 11:10:19 -0400

Shure Incorporated is celebrating its 90thyear as an industry leader in professional audio. From its humble beginnings as a one-man company selling radio parts kits, Shure now offers a diverse portfolio of wired and wireless microphones, listening products, personal monitoring systems, phonograph cartridges, and conferencing and discussion systems. Shure products have been used by such luminaries as Martin Luther King, Jr., Elvis Presley, and every United States President since Lyndon B. Johnson.

There have been many milestones in the Company’s 90 year history:

- The introduction of the first single-element unidirectional microphone, the Unidyne, in 1939 changed the way microphones are made to this day; an accomplishment that was honored with an IEEE Milestone Award in 2014.

- During World War II, Shure provided microphones to the U.S. military, meeting all military testing specifications for its products that the Company continues to uphold.

- The SM57 and SM58, developed in 1965 and 1966 respectively, remain two of the most popular and widely-used microphones in the world today.

Several recent additions to the Shure product portfolio have set new standards for audio quality and performance. The Shure Axient® Wireless Management Network was the first wireless microphone product to detect interference and automatically change frequencies. SE846 Sound Isolating Earphones feature a groundbreaking low-pass filter, a true subwoofer that enables deep low-end performance without sacrificing clarity or detail. And, the soon-to-be-released MOTIV digital products are a new plug-and-play microphone line suited for individuals looking to capture high-quality audio for vocal/acoustic recording, podcasts, YouTube videos, field recording, and more.

“Our founder, S.N. Shure, was dedicated to creating products of exceptional sound quality, durability, and technical innovation,” said Sandy LaMantia, President and CEO of Shure Incorporated. “His vision, combined with the passion, expertise, and creativity of our Associates has led us through 90 years of success. We are very appreciative to all of our customers and channel partners for their support over the years.”

CEA: Telecommuting, e-Commerce Cut U.S. Energy Usage and GHG Emissions

Thu, 23 Apr 2015 10:07:58 -0400

Our use of consumer electronics (CE) for telecommuting and common e-commerce activities such as e-reading is lowering the country’s energy use and reducing its greenhouse gas (GHG) emissions, according to new research released today by the Consumer Electronics Association(CEA)®.

CEA’s study The Energy and Greenhouse Gas Emissions Impacts of Telecommuting and e-Commerce says that in 2013, telecommuting or teleworking reduced U.S. energy use by the equivalent of as much as three power plants, or the annual electricity consumption of almost 750,000 households. The equivalent energy savings from e-commerce – the use of e-newspapers and e-books – is roughly that of as much as one power plant, or the yearly electricity consumption of more than 275,000 households.

“While innovation is constantly developing more energy efficient consumer electronics, the very use of these devices for activities such as teleworking and e-commerce is also leading to significant environmental benefits,” said Gary Shapiro, president and CEO, CEA. “The more people and businesses who use technology to telecommute and engage in e-commerce, the fewer cars and exhaust we have on the road, the less gasoline and electricity we need every year, and the greater the energy savings from lower production and delivery of paper materials.”

According to the CEA study, referencing the 2009 National Highway Transportation Survey, almost 11 million workers telecommuted at least once per month in 2013. That telecommuting reduced our nation’s annual vehicle miles travelled (VMT) by a weighted average of almost 1,400 miles per telecommuter – roughly the distance from Washington, D.C. to Denver, CO. Telecommuting has also reduced total U.S. gasoline consumption by a half a percent – saving one out of every 200 gallons of gas.

"When I first became involved with telecommuting nearly two decades ago, I realized that what we were dealing with was best described as ‘technology-enabled telecommuting,’” said Chuck Wilsker, president and CEO of The Telework Coalition. “Without the consumer electronics innovations that have evolved during this time, we wouldn't have realized the current benefits we're seeing for employers, employees, the economy and the environment. I applaud the technology industry for its progress to date, and am very interested to see what accomplishments are still in store for us."

The use of e-books in 2013 displaced as many as 393 million print books, resulting in a GHG emissions-reduction equivalent to roughly two million metric tons of carbon dioxide. For e-newspapers in 2013, the emissions reductions were even greater. As many as six million daily print newspapers were displaced, producing an emissions-reduction equivalent of roughly three million metric tons of carbon dioxide.

“During Earth Month, when we all more closely consider how our daily activities impact the environment, we’re proud to call attention to the fact that some of our evolving business practices – enabled by consumer electronics – are indeed lessening our carbon emissions and reducing our energy use,” said Douglas Johnson, vice president of technology policy for CEA. “This study is yet more proof that policymakers must take a big picture view of technology’s ability to improve our energy efficiency, not only through the innovation and efficiencies of devices themselves, but also the systemic opportunities for savings.”

This study was conducted by Fraunhofer USA Center for Sustainable Energy Systems and commissioned by CEA. Fraunhofer used a life-cycle analysis approach to evaluate the energy and GHG impacts to compare telecommuting and e-commerce to conventional commuting, paper books, and paper newspapers.

FCC Makes 150 Megahertz of Spectrum Available for Mobile Broadband

Mon, 20 Apr 2015 14:15:51 -0400

FCCThe Federal Communications Commission adopted rules for the Citizens Broadband Radio Service, creating a new spectrum band and taking a major step forward in spectrum policy by authorizing advanced spectrum sharing among commercial and federal operators. As spectrum is a finite resource, today’s action by the Commission will combine spectrum sharing tools and policies to make available 150 megahertz of spectrum for mobile broadband and other commercial uses.

Specifically, the Report and Order adopts innovative spectrum sharing techniques to create a new three- tiered commercial radio service spanning 3550 MHz to 3700 MHz. Today’s action adds 100 megahertz of spectrum newly available for wireless broadband to the 50 megahertz of spectrum already available for commercial use in that band, a significant step towards meeting the nation’s 500 megahertz goal.

The use of advanced spectrum-sharing technology will allow wireless broadband systems to share spectrum with military radars and other incumbent systems, while protecting important federal missions. The Report and Order establishes a roadmap to allowing commercial operations anywhere in the continental U.S. by leveraging spectrum sensing technologies. In an initial phase, coastal protections will be 77 percent smaller than previously contemplated to protect military users. This arrangement reflects extensive cooperative work between the FCC, the National Telecommunications and Information Administration, and the Department of Defense.

In addition to the protected incumbent tier, the Report and Order authorizes two commercial tiers of use in the Citizens Broadband Radio Service. The General Authorized Access tier, which allows any user with a certified device to operate without seeking any further Commission approval, will permit low-cost entry into the band, similar to unlicensed uses. A Priority Access tier will make geographically targeted, short-term priority rights to a portion of the band available through future spectrum auctions. One or more Spectrum Access Systems, operated by private commercial entities, will facilitate coexistence among the different user tiers.

A Second Further Notice of Proposed Rulemaking also adopted seeks comment on several focused topics related to implementation of the rules adopted in the Report and Order.

Shure Counters Attempts To Curtail RF Carve-Outs

Fri, 17 Apr 2015 14:46:43 -0400

The run-up to the Incentive Auction of Television Broadcast Spectrum continues to spur Machiavellian intrigue and tactical skirmishes worthy of an entire season’s worth of Game of Thrones. The auction, scheduled for mid 2016, is expected to see much of the 600 MHz spectrum now used by wireless microphones critical to broadcast sports and ENG auctioned off. However, the FCC had earlier this year approved a 600 MHz “band plan” that allocated 11-MHz-wide guard bands, including a uniform duplex gap (a special guard band used to separate uplink and downlink spectrum), to prevent harmful interference between licensed services.

However, CITA, the trade association representing wireless-service providers, such as Verizon and AT&T, last week filed a technical report asserting that those licensed wireless microphones would cause interference with mobile handsets within 5 MHz of those guard bands.

According to Mark Brunner, director, PR, Shure, the company filed its own ex parte technical report countering CITA’s assertions on Monday April 13.

“We believe the [FCC’s] original band plan did a proper analysis and provided for a proper plan under which all the services specified could co-exist,” says Brunner. “The [CITA] study was flawed on several of its parameters, and we pointed those out in our technical report, along with additional analysis from our own research.”

The importance of RF spectrum in the UHF band, where the 600 MHz range resides, is underscored by the intensity of the lobbying around what is barely a tenth of the spectrum going to auction next year. Earlier this year, the AWS-3 paired-spectrum auction conducted by the FCC drew $44.9 billion for the 65 MHz of that frequency range, nearly three times the initial estimates of what that spectrum would fetch.

Says Brunner, “We have to counter any threats to the commission’s original band plan with accurate, real-world data on how wireless microphones work, in terms of things like power consumption, and their importance to broadcasters.”

Sample Rate

In developing an audio sound for computers or telecommunication, the sample rate is the number of samples of a sound that are taken per second to represent the event digitally. The more samples taken per second, the more accurate the digital representation of the sound will be. For example, the current sample rate for CD-quality audio is 44,100 samples per second. This sample rate can accurately reproduce the audio frequencies up to 20,500 hertz, covering the full range of human hearing.

The Basics of Audio For Video from Shure

Although we seldom think about it, the recording and playback of audio for video involves a series of processes. First, the sound must be captured by a microphone; next it must be recorded on a storage medium; then it must be amplified and played back through speakers or headphones so that it can be heard by a listener. The devices that perform these functions are collectively known as the audio chain.

In the world of professional audio-for-video and audio-for-film the capture, recording, and playback processes are usually handled by different pieces of equipment. Despite continuing improvements in the power and sophistication of audio and video editing software, however, it is usually difficult or impossible to take bad audio and make it good.

To deliver great audio, you must record great audio.

No matter how creative and well-executed the visual aspects of a production may be, and regardless of whether it's posted on YouTube, burned to a DVD or appears on a big, little or mobile screen, the viewer’s experience can be utterly ruined by lackluster audio. To a greater degree than most people realize, sound can “make or break” any video or film project. Using this handy guide from our friends at Shure, you can identify some Shure microphones, monitoring solutions, mixers, and accessories frequently used in audio/video applications.
