Five young adult male subjects with normal larynxes were recorded as they sustained phonation during one normal and three drug conditions. The vocal tasks included obtaining the total fundamental frequency range, tone-matching ability, and vocal fry production, and were performed by the subject (1) before drugs, (2) following injection of a tranquilizer-narcotic premedication, (3) after topical anesthesia of the larynx, and (4) during a drug-recovery period. Results showed no significant differences between conditions on any of the measures of sustained phonation. It was concluded that neither depressed cortical function nor sensory deprivation of the laryngeal mucosa alters the subject’s phonatory capabilities essential to the performance of the selected vocal tasks.

Vocal fold area and thickness were studied as a function of fundamental frequency of phonation using the stroboscopic-laminagraphic (STROL) technique. Two lamina-grams each were measured for seven adult male subjects phonating at fundamental frequencies of 98, 124, 155, and 196 Hz; the phonations were controlled also with respect to time (15 seconds/duration) and intensity (70 dB ±2 dB). Results indicate: (1) a moderate trend for vocal fold area to decrease with increasing fundamental frequency; (2) vocal fold thickness decreases with increasing f o of phonation—thus confirming earlier reports resulting from conventional laminagraphic techniques; and (3) greater intra-subject variability in laryngeal area and thickness may exist than was previously noted.

Six young adult male subjects produced sustained phonation throughout their vocal frequency ranges: first, in a glissando or continuous frequency change maneuver, and second, in discrete intervals at separate trials. Measures of intrinsic and extrinsic laryngeal muscle activity and vertical laryngeal position were related to voice fundamental frequency in the two conditions. Each subject consistently positioned his larynx at a resting level when he was instructed to relax or when he was not performing experimental tasks. All larynx positions during experimental tasks were measured as deviations from this resting level. Subjects showed a close correspondence between their vertical laryngeal positions and voice frequencies—more so for the glissando maneuver than for changes in discrete frequency tasks. In general, subjects lowered their larynges from the resting position for low-frequency phonation and raised their larynges for higher fundamental frequencies. Absolute larynx position for the same frequency was quite varied both within and between subjects. Vertical laryngeal position during phonation most often was directly related to the activity of the thyrohyoid and sternothyroid muscles. Neither vertical laryngeal movement nor intrinsic laryngeal activity showed any pattern of relationship to changes between modal and falsetto voice registers.

Purpose: The effect of physical exercise on lipid peroxidation was investigated. Method: 27 healthy young adult male subjects were included in this study. Urine samples were collected before and after exercises. Urinary malondialdehyde and creatinine levels (Cr) were measured. Results: Urinary malondialdehyde levels were increased by exercise. While pre-exercise malondialdehyde levels were 5.02±1.26 nmol/mg Cr, post-exercise levels were 6.13±1.84 nmol/mg Cr (p<0.05). Conclusion: These findings indicated that physical exercise induced lipid peroxidation.

Similarities And Differences

This article aims to look at the similarities and differences in the fundamental frequency and formant frequencies using the autocorrelation function and LPCfunction in GUI MATLAB 2012b on sound hijaiyah letters for adult male speaker beginner and expert based on makhraj pronunciation and both of speaker will be analysis on matching distance of the sound use DTW method on cepstrum. Subject for speech beginner makhraj pronunciation are taken from college student of Universitas Gunadarma and SITC aged 22 years old Data of the speech beginner makhraj pronunciation is recorded using MATLAB algorithm on GUI Subject for speech expert makhraj pronunciation are taken from previous research. They are 20-30 years old from the time of taking data. The sound will be extracted to get the value of the fundamental frequency and formant frequency. After getting both frequencies, it will be obtained analysis of the similarities and differences in the fundamental frequency and formant frequencies of speech beginner and expert and it will shows matching distance of both speech. The result is all of speech beginner and expert based on makhraj pronunciation have different values of fundamental frequency and formant frequency. Then the results of the analysis matching distance using method DTW showed that obtained in the range of 28.9746 to 136.4 between speech beginner and expert based on makhraj pronunciation. Keywords: fundamental frequency, formant frequency, hijaiyah letters, makhraj
