The patient is requested to repeat a word several times while the provider auscultates symmetrical areas of each lung. The numbers "ninety-nine" or "sixty-six" are traditionally mentioned. The choice of "ninety-nine" is the result of a literal translation. The test was originally described by a German physician who used the phrase "neun und neunzig" (pronounced ˈnɔʏnʊntˈnɔʏntsɪç), which he found would cause maximum vibration of the chest. The translation, "ninety-nine", has fewer vowels and is less effective in evoking the phenomenon.2 Better phrases in English include "toy boat”, "Scooby Doo", and “blue balloons".
