Acoustic analysis was made of 154 voices of healthy non-smokers adults. A sustained vowel /a/ was recorded on a mini-disc. Acoustic analysis was carried out with Dr. Speech Science software. Fundamental frequency (F0), standard deviation of the fundamental frequency (SD F0), jitter PPQ (%), shimmer APQ (%), harmonic-to-noise ratio (HNR), and normalized(More)
ORL emergencies attended at in a general hospital for a year were studied from 1-7-1990 to 30-6-1991. 168,145 emergencies were received of which 3,101 (1.8%) were attended by an otorhinolaringologist.
