Most people follow this belief but if you had studied acoustics and the
science of materials, you would know that materials react to air-borne
sound by a mixture of:-
- Reflection
- Absorption (as heat)
- Transmission (passing directly through)
It
is only when sound pressure of a sufficient volume (and that's
important) at a material's Resonant Frequency occurs...that the material
can 'vibrate'.
You do know of course that the Resonant Frequency of
most tonearm/cartridge combinations is 6-15 Hz and this is well below
the frequency reproduction ability of all commercial loudspeakers and
almost all subwoofers as well?
It in only in this frequency band that
any vibration of the tonearm/cartridge can be observed. There is no
'alternate' vibration phenomena unless you can direct us to the relevant
scientific papers
Halcor, the second to last statement here is plainly ridiculous- and may be why you are having trouble understanding how this works. The resonant frequency of the arm and pickup is irrelevant- that affects tracking and the ability to play bass but has no bearing on the fact that higher frequency vibrations can be transcribed by the cartridge. Were this not so as you state, it would be impossible for the cartridge to put out anything at all!
You seem to use the term 'vibrate' as if somehow it were a different genus to 'resonate'?
It is unimportant whether the vibration is occurring at a resonant frequency or not- its vibration either way- just more of it if its at a resonant frequency.
If air-borne sound pressure is a problem in the turntable playback
system, then every increase in volume would of necessity degrade the
sound.
Correct.
There are tens of millions of turntable systems where turning up the volume is heard to IMPROVE the sound quality noticeably.
This statement is false.
Dietrich knows a thing or two about turntables, arms and cartridges.
And gosh....what are those?
They
look like tonearm pods and did he say in the interview that the tops of
the pods are totally isolated from the plinth and structure?
They look like pods but they are part of the plinth. Go look at the video again. This looks like an excellent machine! It does not support your position.
If any other sound frequency is used there will be NO vibration in the material? This with any energy level in the sound?
Correct....unless you define the transmission of sound through the material as caused by vibrating molecules.
Not in an imperfect world. I am sure the word NO was capitalized for a reason. Damping material damps, but cannot remove all vibration, unless its perfect. It isn't. Its very effective for sure, but not 100%.
No strawman argument from me Ralph, at least not intentionally. I’m with ya, man!
Got it- I sorted that out a bit later.
