I'm about to board the first leg of a circumglobal trip, starting in Honolulu, Hawaii. I am bringing my trusty B&K Type 2250 hand-held sound analyzer, with the 4189 microphone, which will let me go down to 6.3 Hz and provide accurate sound pressure level (spl) estimates in 1/3 octave bands. So on 18 November at 2PM local time I can state with reasonable confidence that the spl at 6.3 Hz at the United Miles club is 55db, peaking around 65db at 10 Hz. I'll keep making routine logs as time and opportunity permits over the next 2.5 weeks.
