Classical music - not excessively loudly but of course orchestral

Digital sources - not vinyl.

An orchestra even in the auditorium can peak at over 120dB.
Do you have a reference for this? I have been looking for credible
sources for peak orchestral SPLs in the auditorium for a long while.
It's a 'well known fact' amongst audio professionals. Google it.
I have quite a few health & safety measurements of very good credibility
inside the orchestra and a few at the conductor's rostrum.
In other words completely useless because they haven't the tiniest clue what
they're measuring. Thankfully or even orchestras would have to be banned from
playing for HSE reasons.
However I have only semi-credible figures for places in the auditorium and they
only go up to 109 dB SPL.
A or C weighted on fast or slow response ? The average dB meter is about as useful
as a wet blanket when measuring either impulses or frankly most music. There is no
correlation between industrial hearing damage levels as measured by a typical dB
meter and music because the waveforms and wavefronts are WILDLY different.
