Wether it makes a loud sound or not up to anyone who hears
it. "Loud" is a subjective description of a perceived sound.
Incorrect; it is possible to objectively measured the intensity of a
sound. That sound does not need to be perceived by a human ear; it
could be detected by a microphone
To borrow a phrase from Dan Aykroyd, "Tholen, you ignorant slut,"
Loudness is not the same as sound pressure level (SPL).
The two are related, but they are not synonymous. The relation was
documented by a study done by Bell Labs over 70 years ago, and refined
since then. The relation is shown in "equal loudness countours" that
are explained/shown here among a lot of other places:

But, if I know my audience, I'm pretty sure that point will continue
to be lost on you. :-) Whether you were dumbing down your response
for your audience doesn't change the fact that your posts indicate
that you still don't seem to understand:
o Loudness and SPL aren't synonymous
o SPL _can_ be objectively measured.
o Loudness as defined by the pro audio, music, scientific, and
all other communities other than , is a
perceived measurement and cannot be related to SPL without
using ears attached to humans.
But perhaps I'm just using terminology that's going over you head. :-)
For some reason (s)he has decided to stubbornly deny the obvious and
continue to misuse the term.
You're erroneously presupposing that I used the term "loudness".
It's probably a lost cause.
Especially when you can't properly read what I wrote.
The issue has been fully exposed here; readers can judge the correctness
of the assertions on both sides.
Indeed, and the readers can see for themselves that I didn't use the
term "loudness".
