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.
