Introduction/Aim. Voice is an acoustic phenomenon that must be viewed multidimensionally. In the quantitative assessment of voice characteristics, the use of acoustic parameters becomes a necessary method of analysis. The aim of the paper is to examine whether there are differences in the acoustic parameters of the voice (the average value of the fundamental frequency - Fo, variations in the height of the fundamental frequency - Jita, and variations in the intensity of the fundamental tone of the larynx - ShdB in people with organic voice disorders with reference to gender and age). Methods. The research included 30 subjects with organic voice disorders (inflammatory processes in the larynx and various allergic diseases), of both sexes (female n = 13, male n = 17), aged from 13 to 85 years. The first age group consisted of respondents aged 13 - 40 years, and the second age group consisted of respondents aged 41 - 85 years. The acoustic parameters of the voice were processed with a computer program for multidimensional vocal analysis model 4300 of the "Kay Elemetrics" voice laboratory. Results. The results of the analyzed parameters (Fo, Jita, ShdB) show that the mentioned parameters deviate from the reference values in women. Analyzing the acoustic parameters of the voice in older and younger subjects with organic voice disorders, it can be seen that there are significant differences between the two groups of subjects in the acoustic parameters of the voice in older subjects. Conclusion. Considering the importance of voice and speech for social development, these research findings imply the need to describe the quantitative and microstructural characteristics of the voice in individuals with organic voice disorders, thereby providing vocal pathologists with a better understanding of the relationship between the investigated independent factors of sex, age, smoking status, and voice, improving their ability in the process of diagnosis, therapy and rehabilitation of organic voice disorders.

Uvod/Cilj. Glas je akustički fenomen koji se mora sagledati iz više uglova. U kvantitativnoj proceni karakteristika glasa upotreba akustičkih parametara postaje neophodan metod analize. Cilj našeg rada je ispitati da li postoje razlike u akustičkim parametrima glasa (prosečna vrednost osnovne frekvencije - Fo, varijacije u visini osnovne frekvencije - Jita i varijacije u intenzitetu osnovnog tona larinksa - ShdB kod osoba sa organskim poremećajima glasa) u odnosu na pol i starost. Metode. Istraživanjem je obuhvaćeno 30 ispitanika sa organskim poremećajima glasa (zapaljenski procesi u larinksu i različita alergijska oboljenja), oba pola (žena n = 13, muškarac n = 17), starosti od 13 do 85 godina. Prvu grupu činili su ispitanici stari od 13 do 40 godina, a drugu grupu ispitanici stari od 41 godine do 85 godina. Istraživanje, analiza i obrada podataka obavljeni su na Klinici za uho, grlo i nos u Kliničko-bolničkom centru „Zvezdara" u Beogradu. Akustički parametri glasa obrađeni su kompjuterskim programom za višedimenzionalnu analizu vokala, model 4300 glasovne laboratorije Kay Elemetrics. Rezultati. Rezultati analiziranih parametara (Fo, Jita, ShdB) pokazuju da navedeni parametri odstupaju od referentnih vrednosti kod žena. Analizirajući akustičke parametre glasa kod starijih i mlađih ispitanika sa organskim poremećajima glasa, uvideli smo da postoje značajne razlike kod starijih ispitanika. Zaključak. Uzimajući u obzir važnost glasa i govora za društveni razvoj, ovi istraživački nalazi impliciraju potrebu za opisom kvantitativnih i mikrostrukturnih karakteristika glasa kod osoba sa organskim poremećajima glasa, čime se vokalnim patolozima pruža bolje razumevanje odnosa istraženih nezavisnih faktora pola, godina starosti, pušačkog statusa i glasa; tako bi se poboljšala njihova sposobnost u procesu dijagnostikovanja, terapije i rehabilitacije organskih poremećaja glasa.
