Effect of Paan Masala on Voice Parameters

Abstract

Introduction: Ingestion of paan masala (a mixture of areca nut with catechu, slaked lime, and added flavoring agents) is one of the means of smokeless tobacco usage which can also have adverse effect on voice such as dryness in vocal folds which in turn may result in depletion of mucosal layer of the vocal folds. Aim: Aim of the study was to investigate the consequence of paan masala usage on voice parameters and to compare the acoustic parameters amid two groups who were paan users and non paan users respectively. Method: A total of 120 samples (3 trials of phonation of sustained vowel /a/) were obtained from male participants between age ranges of 18 – 40 years. 60 recordings were taken from 20 individuals who indulged in intake of paan masala from past 5-10 years. Another 60 recordings were from 20 individuals who were non paan masala users. The recorded samples were subjected to two types of analysis viz. perceptual evaluation was carried out by 10 qualified speech language pathologists based on standardized voice rating scale and acoustic analysis was done using clinically acceptable software. Results: Results of perceptual analysis indicated increased breathiness which was supported by acoustical NNE. Greater values in jitter, shimmer and Normalized Noise Energy (NNE) in paan users indicates of being at risk of having vocal pathologies. These parameters of voice had a significant difference between paan users and individuals who do not consume paan. Conclusion: The results do indicate that consumption of paan poses an impending threat to voice which is evident in abnormal acoustical findings and it is essential for people to be aware of the consequences of devouring paan for mere pleasure of minutes.
