Pretty weird you would believe RF is not an issue in audio. Oh, well moving right along. As for pressure maximums, they can be anywhere in the room, you won't know for sure where exactly they are in the room unless you map out the entire 3D space of the room. This is why instructions are provided with tiny little bowl resonators, to minimize the effort necessary to find ideal locations. Obvious no two rooms are the same acoustically.

"Pretty weird you would believe RF is not an issue in audio. Oh, well moving right along."

Yes but what i said was "AS far as RF, my phone "hears" 2.4GHz but my ears don't"
So are you suggesting yours do?

  You are late to the many posts on this forum during most of last year here on the dodgy subject of what is the audio signal and how does electricity in audio circuits work?
  The short answer is yes, your ears hear the *effect* of Radio Frequency interference. Obviously we don't hear RF directly, that would be absurd. They aren't acoustic waves.
  The reason is because radio frequencies are *electromagnetic waves*. And external electromagnetic waves produce noise and distortion in audio signals because audio signals are themselves, you guessed it, electromagnetic in nature. Poynting vector with E and B fields.
  Analogous to the deleterious effects of RF on our hearing is the effect of Very Low Frequency seismic type vibration, also outside nominal 20-20k Hz audio frequency bandwidth. Seismic type vibration is around 1 Hz - 20 Hz approximately.
  The ball is in your court.

    everything matters... we just do not know what to measure and there is NO such thing as objective as we do not possess COMPLEAT knowledge, therefore all is subjective. Philosophy 101.
