Guest Editorial

Don't Be Such a Scientist!

Most of us audio types probably visit an audio forum once in a while -- some of us daily. And if you do, you are familiar with the scenario: an "engineering type" gets involved and starts to explain an issue. Most engineering types like to explain things, to tell others with less experience and knowledge what they are doing wrong and how they can do it better. They inundate you with facts, figures, links to engineering papers, and so forth, and expect that the other guy flows over with gratitude. But, funny enough, it doesn't happen that way. The "other guy" gets angry about being corrected all the time. He didn't come here for that, he came to talk about his projects, and discuss his hobby and his latest creation.
Remember Al Gore's An Inconvenient TruthShortly before that another similar documentary was released: Too Hot Not To Handle.
Both of them were on the issue of global warming.
But, do you remember that other documentary? Neither did I. Did you know that Gore's movie, which is basically a spiced-up PowerPoint presentation, earned $50 million? What made these movies so different? Too Hot Not To Handle was 100% accurate, had all the right figures and simulations. It was also boring. An Inconvenient Truth has been shown to have some errors in a few places (although accurate in a general sense). Some of the graphs were "enhanced" to let the trend stand out better. But it was NOT boring, because it appealed not just to the brain, but also to the heart, to the gut; and then there was Gore's sex appeal (it's the eye of the beholder, of course).
Then, there was Randy Olson, a guy who left a tenured position (the pot of gold for any academic person) to go to Hollywood. A scientist turned communicator. His short movie Flock of Dodos: The Evolution-Intelligent Design Circus earned him praise because it was a scientific movie that got to the heart, the gut, and so forth. It may seem preposterous to compare an audio forum with a successful moviemaker, but we can all learn a lot here, especially we engineering types.
If you, as an engineer, want to explain to a friend or colleague that he has his cascodes all wrong, you are in the same business as Hollywood. You are telling a story that you hope will stick and have an effect. So far, Hollywood is much, much better at it.
Facts are important. Engineering is important; none of our audio marvels would exist without solid engineering. Errors should be avoided. But, if the story you tell is boring, you're wasting your time. And as soon as you find out you're wasting your time, you get frustrated and angry - you've lost.
Tell the engineering story from the heart, from the guts. Tell your own crooked path to learning, making mistakes, the joy of doing it right. By all means, be sure to get the facts straight. But don't be boring, don't be such a scientist!

Grounding and System Interfacing
By Gary Galo
Inspired by a presentation by Bill Whitlock, President of Jensen Transformers - a three-hour tutorial seminar titled "Audio System Grounding and Shielding: An Overview" - during the Audio Engineering Society (AES) convention in New York, Gary Galo decided to investigate a little more into the subject and do some reviews of the mentioned equipment. "It's time to clear up some misconceptions regarding grounding and audio gear," says Gary Galo in this article, originally published in audioXpress January 2007.  Read the Full Article Available Online

Voice Coil Spotlight
New EC Driver Technology 
By Jens H. Waale
In this article, originally published in Voice Coil April 2014, the author and inventor describes the Eddy Current (EC) driver concept, a new kind of electromagnetic transducer for sound and ultrasound reproduction. The transducer is unique among electromagnetic transducers in that the force acting on the membrane is uniformly distributed over much of it, as in an electrostatic sound transducer, but with substantially more power per square unit. As a narrow-band transducer, the driver can become exceedingly efficient in multiple applications.  Read The Full Article Available Online
