Ever Present Vibrations and Their Deleterious Effects

Thinking about vibration and the effect is has on electronics, and cartridges, a question came up.

If vibrations from the sound of the system affects the sound of the system, negatively, as we all know it does [vibrations cause the wires in electronic equipment to move, and since they are often in some kind of magnetic field(s), these vibrations generate electric current in the wires that has nothing to do with the sound. Egro: noise]….

…then what about other vibrations?

Especially second story vibrations:

1. Here, we have wind that vibrates the house a lot
2. People walking or kids playing
3. Vibrations from the refrigerator motors
4. Vibrations from other people and elevators when in an apartment building.

And even ground floor vibrations:

1. Passing traffic, especially when the listening room location is near a busy road.
2. Some people have big freezers and furnaces down stairs, and sometimes the vibrations of these are transmitted though the foundation.

Anyway, our main listening room is upstairs, and I wonder how much higher a noise floor we have hear because of environmental vibrations.

Hard to test, because when it is really windy, and the house is shaking – it is also very noisy just from the noise of the wind.

Similarly with large trucks, that might be a mile away, but we can hear them [it is quiet up here] and once in a while feel them, especially when they use their exhaust brake [which is illegal up here, but if you gotta slow down, ya gotta slow down….]

So, there are indeed probably deleterious effects from environmental vibrations, causing a raising of the noise floor, but the noise from the things causing the environmental vibrations raises the noise floor itself, and even higher than that caused by the vibrations it causes, so it is probably not worth worrying about [i.e. if kids are running around, pounding the floor with their little feet, they are probably screaming too ;-)].

Not worth worrying about? Whew! OK, good. Neli! We can go on with our lives now. Such as they are….

Press as the Public Relations Arm of Industry

There are a lot of pieces and parts of the show report – kind of sprinkled in amongst almost 2000 photos – and even I forget where I said what.

But one of the themes this year was influenced by a ‘Cranky Geeks’ episode (online or special TiVo download) that crystallized, for me, the problem with most reviews in our industry. Although Cranky Geeks was talking about the software industry – it applied equally well to ours [and the Washington Press Core as well, but let’s not go there].

That is that the press is serving as the Public Relations arm of the Industry. The corporations. They take press releases [well, in high-end audio, we don’t need no stinking press releases – so our reviewers have to do more work], massage it, and spit it back out as a review.

Thinking about this off and on during the last few weeks as I do the kind of laborious task of juggling CES photos, I think that there are telltale signs of reviews that are really just PR – that really just server as pages for the industry to link to, to serve as an incentive for the industry to donate free equipment to get more of, a safe place to advertise on.

And those signs are that it reads like PR.

PR, like your prototypical salesperson, never, ever, ever say anything bad about what they are selling. Nothing that can even be *slightly* construed as negative about the piece of equipment.

Now reviewers are famous for putting in clues that seem like they maybe might be a hint at what they really think about the component.

But, think about it. All components have a sound and have issues. .

So most reviews are like describing a car crash by saying over and over again how great the car was – and about what songs were playing in the car at the time of the crash.

Anyway, I grew up respecting the press as being honorable, reporting what was really happening, very often DIFFERENT from what the official spin was about the events. Now it is all in support of making more money. Not making waves.

And the only reviewer who I have any confidence in that they actually write real reviews is Mike Fremer.

Sure, he ignores his prejudices, and ignores how badly his poor sad room affects the sound, and ignores the fact that much of his system equipment is flawed and affects what his results are going to be. So he ain’t perfect [and he has some anger management issues – or at least, he should learn to count to ten before posting. I know. I know. Many people want me to count to a billion before posting]. But I think he is the best we got. [Which is saying a lot about the state of the press industry here, huh?]. And I think he has been getting better.

HP hasn’t written a real review for years and years. Art Dudly, Srajan are runners up – and they may be just as good as Mike, but I just don’t read enough of their reviews, especially of equipment that I am familiar with that have easily agreed-upon issues.

As far as the other reviewers go, as far as I have time to read their copy – uh, well, there is really no reason for me to go farther.

I haven’t met Mr. Fremer, nor Art Dudley and have no specific desire to do so [I emailed once or twice with Fremer about 6 years ago]. I have met Srajan at shows when he used to go to shows here in the U.S. [and he is the only member of the press that acknowledges we exist – all the others try hard to ignore us because we encroach on their (abandoned, as this post testifies) domain] but he doesn’t review stuff I am familiar with – and I instead mostly end up reading his editorials.

Anyway, to wrap this up – it is not like reviewers, in general, are any more a**holes than the rest of us – in fact, of the few I see at shows, most of them are just like the rest of us. It is just that I see the responsibilities of being a reporter differently than they do.

Next Stop: CES 2008. Prepare for Photos and Commentray Extraordinaire

… Well, you will have to wait until AFTER the show starts.

Sorry.

According to the CES pamphlets this year – this is what the show is all about:

and

Funny how they focus on home audio when it is treated like such a distant cousin to PCs and Cell Phones and Cameras and even Car Audio and, oh yeah, video.

Face it, we lack glamor. Josh over at SonicFlare.com is trying to help, comparing equipment to sports cars.

Let’s see, what can we do?

Neli’s too busy to read this post, so how about:

The Sophia Loren of amplifiers. The Rachel Welch of speakers…?

McIntosh can get Brittney Spears…

No? The approach too libelous?

How about… No, can’t use gemstones: the platinum version of things this day is way too tired of a adjective .. or is it metaphor?

Endorsements would be cool…

These speakers are endorsed by Arnold as true Kick Alien Butt class loudspeakers. Spok says these amps are ‘The logical choice’.

Still gonna get us sued.

Well, we know how motorcycles and alcohol do it. But any nudity in Stereophile seems to bring out the church brigade. [I wonder what percentage of us WANTS high-end audio to stay a niche hobby.?]

One way is obvious, have the print media not dumb down their offerings to the ‘buyer guide for everyman’ state. Such a cop-out. Magazines in Japan have glorious audio porn and present the ultra high-end in a very desirable, Wish You Had These kind of style. You go to the magazine stand in THIS country, and look at the car mags… 1 in 20 is a buyers guide – the rest are high-end specialty car mags. Somebody has a clue over in THAT aisle.

Well, so now you know where we stand, and where this blog stands. And where we are headed.

I know, a lot of posts in a row – but you will be rid of me for a few days… next time you hear from this blog will be from smoky, sexy, crowded Las Vegas!
