Assessment of Multidimensional Voice Program (MDVP) Parameters in Workers

Summary

MDVP (Multidimensional Voice Program) has several parameters that can assess voice quality objectively, including Base Frequency (F0), Jitter, Shimmer, NHR (Noise to Harmonic Ratio), VTI (Voice Turbulence Index), and ATRI (Amplitude Tremor Intensity Index). MDVP may provide an objective yet non-invasive and comfortable alternative to assess voice quality - and to some extent, diagnose voice-related abnormalities. The utilization of MDVP in clinical settings is quite common but using it concerning occupational health is rare, especially in Indonesia. No study had reported usage of MDVP to assess voice quality in any occupational voice user group or reported a thorough comparison of MDVP parameters between occupational and non-occupational voice users. With an increase in the realization that voice can be an essential occupational modality, MDVP may become a practical alternative modality in assessing voice quality and occupational-related voice injury in clinical settings. This study will determine any association between occupational voice users and their MDVP parameters from medical records and the MDVP database in Dr Cipto Mangunkusumo Hospital, Jakarta. The study also tries to see whether there is any value in using MDVP to assess voice quality in workers.

Multidimensional Voice Program

MDVP (Multidimensional Voice Program) is a computerized acoustic analysis used to analyze sound quality using various parameters. Multidimensional Voice Program (MDVP) 4500 produced by Kay Elemetric Corp was used for voice evaluation. Research subjects were asked to make a vowel sound /"a"/ using the same tone and intensity as the subject's daily speech. The researcher will give an example before letting the research subject tries. Voice recording was done using a microphone connected to a computer with the MDVP program. Voice recording was done in a quiet room for at least 3 seconds with a microphone distance of 10 cm from the mouth of the research subject. The recorded sound will be directly analyzed with the MDVP program. Sound recording was done 3 - 5 times, and the best sound acoustic analysis results were used for the study.
