Hi Dobroide--
Such test recordings do bring out the worst in mics and pres! Their
primary value is to help one determine whether the differences you
can hear are significant to you. Correct, you are not likely to
playback a recording of room tone at a loud level. It is important to
turn down the playback to a comfortable, realistic level. In many
cases, noise and other performance differences will be lessened.
Differences in the acoustic settings will usually obscure one's
ability to compare different tests (along with other variables). Thus
the term, "room tone." That said-- if you want to hear the tests
compared:

If you listen to just the top registers, you can try to compare only
the HF noise between the mics. It might be interesting for you to try
and discern a difference in the noise character between your mkh-30
and mkh-60 mics. Rob D.
