A special phonophotographic camera makes possible the photographing of nasal resonance together with a time line. On the basis of these photographs, it is shown that each vowel has a specific nasal element in its resonance, the duration of which varies directly with the closeness of the vowel. It is shown further that the duration of nasal resonance in vowels phonated by individuals with badly nasal voices is greater than in vowels phonated by those having superior voices.
