In Reply to: Who here DOESN'T believe in The Freeze Effect? (Freezing items will improve sound?) posted by Posy Rorer on April 10, 2007 at 11:00:17:
I do not believe you know what you are talking about relative to audio because I do not believe you can really hear all the tweaks you believe in and claim to hear.Tweaks are easily tested for audibility.
'I know what I hear and could not be wrong' is not reliable evidence.

Hi.by quantitative measuremnts due to limited knowledge & available instrumentation todate. DBT may help.
That's why we have to be open-minded & give such tweaking the benefit of doubt provided such tweaking can be at least rationalized by some scientific principles or theories.
FYI, I am subjective, rationally.
Like a $500 wooden knob as claimed by its vendor can improve the sound bigtime. One may instantly dismiss it as snake oils.
But if one takes a second thought. The mass of the knob can damp out the peaky resonances of the rotating shaft of the volume control
wiper, resulting sonic improvement.At least there is some remote scientific rationing behind it, yet to be proven by the resultant resonance spectrum analysis or otherwise.
That's why I asked for technical explanation why a florinated water pot or some colourful labels can improve sound. How come minus 20C-30C domestic freezing can PERMANENTLY change the molecular stress balance of a metal? As I said, I am all ears.
We might have missed a lot out there. Nobody knows everything. Correct?
Let's be patient to recieve some technical reasoning from those who have made such sonic claims on their tweaks.
We entertain tweaks there in PHP, privided all such claims come up with some scientific reasoning, to say the least.

Hi“FYI, I am subjective, rationally.

At least there is some remote scientific rationing behind it, yet to be proven by the resultant resonance spectrum analysis or otherwise.”Logical an all but examine how the device in question actually works. Most potentiometers already have silicone damping in them to make them “feel nice” but unless you have a dirty pot, you can tap on it with your finger and not hear anything in the sound coming out. This is important as simply tapping on it produces G forces millions of times larger than any airborne sound would impose. Usually, Tubes and mcrophones etc are about the only things in audio that are micro phonic (where mechanical vibration has an effect on the signal).
Lastly, from a acoustic / mechanical point of view, simply substituting a wood mass in place of a plastic mass on the end of the shaft in it self (being a mass) could have no effect on Q, resistance to motion is damping, this is what reduces “Q”.
Sadly also, a spectrum analysis would not show any difference, there is no mechanism for the improvement to take place. Also, a wood knob vs plastic would have no change in Q if you were to vibration test the assembly. In my opinion, your first reflex was correct, this is snake oil in the shape of a knob with an exotic, slightly plausible explanation..
Best,

... you could admire her system and then say "Nice Knobs Babycakes"Hopefully this will happen before I die.
I have already had the glorious opportunity to address a big-boobed woman in a supermarket produce department holding two mellons with: "Nice mellons!" Fortunately she laughed harder than I did or it might have been my last day on the job.
And they told me there was no future working in a supermarket produce department!
