“…The term vocal professional includes a range of occupations that require the successful use of voice and speech, such as singers, actors, teachers, radio and television presenters, priests, commanders, lawyers, street vendors and many others. For the vocal professionals, a healthy and pleasant voice is important, because with a disrupted speech and voice they would not be able to do their job successfully [3].…”

Introduction. The human voice is an important characteristic that enables the distinction of human from other living beings. Otherwise, it represents a picture of a person΄s personality, his health, mental and emotional state. The research aims are to determine the voice characteristics of vocal professionals with diagnosed vocal cord nodules by subjective voice assessment and objective voice measurement before and after vocal rehabilitation. Methods. This study has involved 25 examinees, aged 23 to 56. The subjective voice assessment was conducted with the Voice Handicap Index - VHI questionnaire and the objective voice measurement by a computerized laboratory for voice analysis ''Kay Elemetrics''. The obtained data were processed using descriptive and analytical statistics. Results. Before the vocal rehabilitation and the subjective and objective voice measurements, the examinees had greater psychosocial difficulties associated with their voice quality. After two months of vocal rehabilitation, there has been a significant improvement in the voice of all subjects on the VHI scale. A statistically significant and highly statistically significant improvement have been noticed in six out of seven analyzed parameters of vocal A, by the objective measurement of voice. Namely, the obtained values - the percentage of jitter Jitt (%), the percentage of shimmer Shim (%), the relative average perturbation value RAP (%) and the coefficient of fundamental frequency variation - vFo were highly statistically significant (p < 0.01). The VTI - voice turbulence index and the SPI - soft phonation index also improved, the observed difference was statistically significant (p < 0.05), while the observed difference in the FTRI parameter was not statistically significant (p > 0.05). Conclusion. Vocal rehabilitation has influenced the improvement of the voice quality, which means that the results obtained by objective voice measurements were more in accordance with the results of the subjective voice assessment.

“…Promjene u kvalitetu ili trajanju glasa ukazuju na prisustvo oboljenja i zahtijevaju adekvatnu dijagnozu i rehabilitaciju [3]. S obzirom da je glas produkt vibratornog kretanja glasnica i rezonantnih efekata vokalnog trakta, instrumentalno praćenje samog vibratornog procesa je jedan od bitnih aspekata objektivnog instrumentalnog ispitivanja glasa [4]. Kvalitetna procjena glasa je veoma značajna, jer na osnovu nje vokalni terapeut osmišljava plan i program tretmana, i sprovodi adekvatne metode i tehnike koje podrazumijevaju ultimativnu brigu o glasu svakog pacijenta [5].…”

Uvod. Glas je produkt vibratornog kretanja glasnica i rezonantnih efekatavokalnog trakta, stoga je instrumentalno praćenje samog vibratornogprocesa jedan od bitnih aspekata objektivnog instrumentalnog ispitivanjaglasa. Neodgovarajuća visina i neprimjerena glasnost, kao i pojačana nazalnost, predstavljaju osnovne karakteristike glasa kod osoba sa oštećenimsluhom. Cilj istraživanja je bio da se uradi detaljna analiza i poređenje akustičke strukture vokala A kod ispitanika sa oštećenim sluhom i ispitanikasa urednim sluhom i normalnim glasom.Metode. Ukupan uzorak je činilo 40 ispitanika, uzrasta od 17 do 20 godina(18,50 ± 1,13), oba pola (50% muškog), koji su podijeljeni u dvije grupe.Prvu grupu je činilo 20 ispitanika sa umjereno teškim oštećenjem sluha(56-70 dB), dok je druga grupa obuhvatila 20 ispitanika bez oštećenja sluha. Ispitanici obje grupe su međusobno ujednačeni po polu i uzrastu (± 3 mjeseca). Istraživanje je realizovano tokom maja 2018. godine u srednjim školama i Medicinskom fakultetu u Foči, i specijalnoj školi sa domom učenika ,,Bubanj” u Nišu.Rezultati. Statistički značajna razlika između ispitanika sa urednim i oštećenim sluhom utvrđena je za 11 od 14 ispitivanih akustičkih parametara vokala A: standardna devijacija osnovne frekvencije (STD), ukupan jitter (Jitta), jitter procenat (Jitt), relativna srednja vrijednost perturbacije (RAP), koeficijent varijacije osnovne frekvencije (vFo), shimmer (Shdb), shimmerprocenat (Shim), koeficijent perturbacije amplitude (APQ), odnos šumai harmonika (NHR), indeks prigušene fonacije (SPI) i indeks intenzitetaosnovne frekvencije i tremora (FTRI), pri čemu ispitanici sa oštećenim sluhom ostvaruju veće vrijednosti navednih parametara.Zaključak. Prikazani rezultati ukazuju na patološke promjene u glasu kodispitanika sa oštećenim sluhom i potrebu za rehabilitacijom glasa ovih ispitanika.
