I remember it like it was yesterday. I was consulting for a car company and I needed to A/B two tweeters. I dashed over to the nearest RadioShack and picked up a speaker-switching box. Crazy to think about it now – a brick-and-mortar store selling something like that. Of course, RadioShack is just a distant memory now. Or is it? Is RadioShack making a comeback?

Which of the following statements is false? 1. The sun rises in the east. 2. The hands of a clock go clockwise. 3. New technology is always better than old technology. This last statement, of course, isn’t quite as gospel as the others. Sometimes old technology has advantages that cause it to linger longer than we’d expect, or in rare cases, even make a comeback.

In the beginning, Edison created the phonograph, and it was good. It was also monaural. The vertical modulation (referred to as hill-and-dale recording) of the groove neatly encoded the amplitude variations of the analog-input waveform and likewise could reproduce the waveform. If engineers had stuck with hill-and-dale, the world would be a very different place. But they kept tinkering, as engineers are wont to do, and they found an improvement.

A couple blogs back, we discussed the ascent of glorious stereophonic sound in “The Rise and Fall of Stereo (Part One).” Stereo was a true revolution in audio playback, and it quickly condemned monaural to an eternity of lo-fi hell. Audio manufacturers’ marketing departments had an easy time convincing consumers to upgrade to stereo; everyone could easily hear the improvement. Now, 50 years later, stereo is unraveling.

It’s a paradox, that’s what it is. Technology, by nature, charges forward. Its unstated goal is to obsolete itself as fast as possible. If you’re into technology, the only real place to be is on the cutting edge. You must be an early adopter, own the latest and greatest, and camp overnight at the Apple Store. The paradox is that if you are one of those people, you might be envied, or even admired. But you are not cool.

I usually don’t talk to myself, but the other day I was sitting down to my favorite breakfast, a stack of delicious Eggo buttermilk waffles, and I exclaimed out loud, “Man, I need to buy some more syrup!” Later that day, browsing on my PC, I got a pop-up ad for Vermont maple syrup. I exclaimed, “Wow! What a coincidence!” And then my life spiraled out of control.

It has become trendy to bash corporations. And in some cases, if a corporation is big enough and faceless, it's easy to suppose that it's merely a shareholder profit machine that is uninterested in the needs of individuals. But of course many companies certainly do not fit that profile. Instead, you'll find that many small and medium size companies take a very different view of their role in society and, in many case, are family-run businesses. Case in point: Sennheiser and the Sennheiser brothers.

We are equipped with five senses: Sight, hearing, smell, taste, touch. The thought of losing any of them is frightening. Setting aside the question of aging, even the thought of only diminishing any of our senses is unsettling. So, the question is, if a faulty product caused you to suffer an impairment of one of your senses, what kind of compensation would be appropriate?

Ah, the irony. Unwanted traffic noise is a bane of modern existence. Countless engineers have spent entire careers laboring to reduce vehicle noises from engine, exhaust, tires and aerodynamic turbulence. Most drivers and passengers prefer quieter cars; for starters, it makes it easier to listen to music.

The rover Perseverance is scheduled to touch down on the surface of Mars this Thursday, February 18 at approximately 12:55 pm, PST. I dare you to watch this NASA trailer, and tell me these landings aren't the coolest things ever. Also, this rover carries two microphones. If all goes well, for the first time, we'll be able to listen to sounds from the red planet.
