Abstract

Introduction: Acoustic analysis of voice is a method for assessing its quality, which has a relatively low cost. It quite simple to use, and is non-invasive. One of the programs of spectral analysis of voice is the program Praat, which allows to explore its acoustic characteristics and analyze the forms, also its allows to edit sound segments and print the spectrogram.
The purpose: Investigate the acoustic parameters of the voice Ukrainians of different ages and genders and perform the calculation of reference intervals (RI) for these indicators.
Material and methods: We had examined150 healthy Ukrainians aged 18 to 70. The study was performed using a Behringer C1U condenser microphone and Praat software (version 5.1.12.). The following acoustic characteristics of the voice were studied: the fundamental frequency of voice (F0) in Hz, the maximum phonation time (MPT) in seconds, the Harmonic to Noise Ratio (HNR) in dB, Jitter in%, Shimmer in%. Four groups were formed for the study: 1a – young women (18-44 years); 2a – young men (18-44 years); 1b – middle-aged women (45-59 years); 2b – middle-aged men (45-59 years).
Results: Young and middle-aged men showed significantly higher MPT than women of relevant age. The value of MPT in women with age increased slightly, in men decreased slightly. RI for the indicator of MPT, in 1a group is 11,35-31,28 s, in 2a group – 15,55-39,53 s, in 1b group -14,30-33,01 s, and in 2b group –12,59-31,90 s. The value of F0 in young and middle-aged women is statistically higher than in men of the same age group (p <0.001). With age, this figure decreases slightly in women and men. RI for the indicator F0, in 1a group is 107,0-316,5 Hz, in 2a group – 94,1-139,3 Hz, in 1b group – 94,3-339,1 Hz, and in 2b group – 80,3 -174,3Hz.A comparative analysis of the HNR in young and middle-aged men didn’t show significant differences. In middle-aged women this value is significantly higher than in young women. RI for the HNR in group 1a is 14,194-26,946 dB;
in group 2a – 17,328-28,675 dB; in group 1b -15,254-26,536 dB, and in group 2b – 13,545-30,368 dB. The Jitter index in men and young women does not differ statistically. This figure increases statistically in men with age, in women this rate the same level. RI for the Jitter in 1a group – 0,110-0,436%; in 2a group – 0,101-0,472%; in 1b group – 0,094-0,520% and in 2b group – 0,117-0,460%.
A comparative analysis of Shimmer in men and young women didn't show significant differences, but in middle-aged women this figure decreased statistically compared to young women. In men, this figure has not changed with age. The RI for the Shimmer index is 1,974-14,128% in group 1a; 2,592-12,378% in group 2a; 2,008-6,788% in group 1b; 2,016-12,260% – In group 2b.
Conclusions: Indicators of spectral analysis of voice in young and middle-aged women and men are relatively stable and do not change significantly in this time period.
