Prove it to me
How often do we go into a decision making process pre-convinced of the outcome? And, when we do that, how is the outcome affected? It cannot be nothing.
As soon as I hear the catchphrase “prove it to me” I smile. The person has already decided the outcome and now the task of the educator is a magnitude more difficult.
While I am good at offering advice I am as guilty as the next for uttering those very words. So…I have decided to do my best to change my initial reaction from “oh yeah? Prove it to me” to “ok, tell me more”.
It may not be much but sometimes a simple change in mindset can make all the difference in the world.
“Oh yeah? Prove it to me.”
“Tell me more!”
Vibration isolation products are snake oil
We’ve saved perhaps the best for last. “Best” because this is a subject that genuinely gets the hairs on the back of some necks to stand at stiff attention, yet there’s ample proof that it works.
Some weeks ago I published this video of a vibration control product demonstration I saw while at RMAF. Nearly 30,000 people have viewed this video and the number of commenters is one of the highest of all my many videos. Passions run high and I think I know why. The idea that reducing vibrations has an audible impact runs so counter to what we consider normal as to inflame emotions often to the burning point. “It just doesn’t make any sense!” is a rallying cry to get the tar heated up and the feathers collected. Yet, the differences are easy to hear.
Few knowledgeable people would dispute that quieting vibration prone equipment matters: turntables, vacuum tubes would come to mind right away. Perhaps less obvious are capacitors that proliferate within equipment, but these are generally accepted by even the propellerhead measurementists. No, what really freaks people out is speakers.
Speakers make the noise we hear in our rooms and systems. They generate sound pressure and should be immune to their own vibrations, dammit!
Ahh, but sadly, the boxes that hold our speakers add to the melee of sound in the room. At the same time they radiate sound waves those same boxes add time audible vibrations through the floor. As well, some would claim those same floor vibrations are reflected back up into the box to muddle the music even more. If you have the time to closely look at the graphs Dave Morrison shows at the end of the video you’ll gain a better understanding of how isolation products—legit isolation products, that is—actually contribute to good sound.
Is there snake oil in accessories? Oh my, yes. Claims and counterclaims that match Carter and his little pills abound with abandon. Yet, I would encourage the person interested in good sound to wade through the bullcrap to find the truth.
As in any of these Fact or Fiction questions, there’s truth to be found if you’re interested in finding it.
