As stated, the applying a artificially applied ( a strike from a implement or Knuckle) is one that can be reasonably easy to replicate to a very similar outcome by all who do it.
As there are many who do do this, where reports on a outcome are usually ones that are satisfactory, i.e, no noise detected that is of a concern. It does seem it is not too difficult to put measures in place to create an Isolation that is deemed valuable to be in use.
The point of interest, I extended into, was that there are individuals including myself, that have got the desired result from one test type, but have been further investigative with methods to create Isolation.
Furthering investigation and using the usual test method, in my case has confirmed, methods adopted have not been noticeable for their capability to improve the outcome of applying a artificial Kinetic Energy to be transferred.
No sound being produced at he time of a test, is simply that, "No sound being produced at he time of a test. "
There are individuals including myself, that having gone to extended measures to create methodologies to add attempt to improve on the Isolation available. There are follow up reports that are made, that in my assessment share similarities to my own. Where it is stated, that increased attraction is present in relation to the end sound being produced.
In my case, this is not a fantastical appraisal, the effects are real and notable for the impression that is able to be made. I see no reason why any others report should be considered differently, I see no reason to question their findings, but do understand the influences on individual systems in their own environments, are most likely to be varied on the impact being made.
When seeing a contribution from myself on the subject of Isolation, it will be seen that I am keen to encourage an individual to not 'get of the Bus ' , in their Journey of learning about the effects of Isolation, because one change to a Structure has been noticeable for creating a change they have classed as improved or attractive and wanted to be maintained.
My experiences are quite simple and Bass notes are a great indicator to where the end sound is being affected.
Bass notes can be Very Loose, Bloated, Muddy, Overbearing, where the condition when not really have a defined cut off, is starving the upper frequencies of their place in the overall range.
Bass notes can be Taut, Sharp, Clean, Adventurous and Complimentary to the Upper frequencies, where their presence are with equally shared influence on the frequency range.
I can't encourage any individual to decide on how the coherence across the frequencies is most attractive to themselves, but as for my own unique preference for listening to the bulk of my recorded music. The more I can experience of the latter description for Bass notes is being resolved, for myself, the tidier the presentation becomes and the musical encounter I most enjoy is being presented.
Then their is the antithesis to the above preference, when I set aside the time to put Chicago Blues on as a replay, I can quickly feel sold quite short, if it does not come with a dosage of colouration from the former description for a Bass note. Hence, a ESL Speaker Array and its transparency, is speedily swapped out for a Cabinet Speaker Type, the colouration caused by the Cabinet Influences works just fine for myself.
