- Any sound a human can hear, can be measured.
- Even if it can be measured, it is not certain that it can be heard by anyone.
- Whether a sound can be heard or not, can be determined by ABX tests.
- If a human claims to be able to hear a sound, it is possible to either:
a) devise a measurement that can measure it or prove its existence,
b) or conclude the claim is not true. - Electronics and acoustics are sciences. Any claims regarding electronics and acoustics can be measured and must follow physics. Claims not explainable by current science, demands evidence. "Extraordinary claims require extraordinary evidence"
- Neutral audio reproduction can be measured. Humans have individual tastes, but neutral audio reproduction does not depend on taste.
- Audio reproduction is not neutral, if any frequencies are emphasized or deemphasized with regard to the source, or if sounds, that are not part of the source are reproduced. Sounds from the source must reproduced with the correct timing.
- Everything in audio can be measured, but some audio perceptions are not yet well-defined, e.g. soundstage.
- For a tweak to acknowledged, it needs to be measurable, and to be hearable.
