Why Blue Balloons?
Tactile fremitus was first described by a German physician who called for the patient to say "neunundneunzig" (ninety-nine). "Blue Balloons" is an English phrase that closely resembles the sound and vibration emitted from the lungs when saying "neunundneunzig" (a low frequency 'diphthong' phrase).
