TL;DR
Smoking reduces vocal range and dynamic intensity in men, with effects worsening over time and with higher cigarette consumption.
Contribution
This study quantifies the impact of smoking on vocal parameters using phonetography in a controlled observational design.
Findings
Smokers showed significantly lower maximum frequency, vocal range, and maximum dynamic range compared to non-smokers.
Longer smoking duration correlated with reduced minimum and maximum frequencies, vocal range, and maximum intensity.
Higher daily cigarette consumption was linked to lower minimum frequency.
Abstract
To investigate the effects of tobacco use, smoking duration, and number of cigarettes/day on the vocal dynamic field of male smokers. A cross-sectional, comparative observational study was conducted with 62 men aged 18 to 59 years: 31 smokers (SG) and 31 non-smokers (NSG). Vocal dynamic field measurements were obtained using phonetography, which assesses frequency (minimum, maximum, and vocal range) and intensity (minimum, maximum, and maximum dynamic range). Comparisons between groups were made using the Student’s t-test, and correlations with smoking duration and number of cigarettes/day were analyzed using Pearson’s correlation test (5% significance level). Compared to the NSG, the SG showed significantly lower values (p < 0.05) for maximum frequency, vocal range, and maximum dynamic range, and higher values for minimum intensity. Increased smoking duration was associated with…
