Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Voice evaluation for all patients in Dr. Cipto Mangunkusuomo Hospital was done using the Multidimensional Voice Program (MDVP) 4500 produced by Kay Elemetrics Corp installed on a personal computer. The patients were asked to emit vocal sounds /" a "/ using the tone and intensity of everyday speech. The physicians are obliged to give an example first. The patient's voice was then recorded using a microphone connected to a computer with the MDVP program. Sounds were recorded in a quiet room for at least 3 seconds with the microphone 10 cm from the patient's mouth. The MDVP program will directly analyze the recorded sound. Sound recording is done 3 - 5 times, and the best sound acoustic analysis results are used as the final result. The results are then kept in the program's database inside the computer.
Patients who attend the Larynx-Pharynx clinic for MDVP evaluations are usually those who comes for post-treatment monitoring (e.g., post-laryngoplasty), had been diagnosed with a voice disorders, and or by personal or physicians' request. There are various reasons why patients are being assigned to MDVP evaluations - and all of this information will be gathered and used as a consideration during data analysis. For the sake of practicality, the researcher will only extract MDVP data from the past five years. Other considerations will be made to ensure that the data extracted will represent a reliable comparison between occupation status and how it affects MDVP parameters (see more in "Criteria for subjects"). The study will use total sampling, where all available data that fits the inclusion criteria will be used for analysis.
Inclusion criteria
* Patients had their medical records and MDVP data available in dr. Cipto Mangunkusumo Hospital, Jakarta
* Patients are active workers in Indonesia on the time of MDVP evaluation
* Patients are above the age of 18
* Patients can be either an occupational or non-occupational voice users Exclusion criteria
* Patients with incomplete occupational data
* Patient with incomplete MDVP results
Data obtained from the database will be evaluated in SPSS v20 software and analysed to produce descriptive and inferential statistics. The inferential statistics will consist of univariate analysis and bivariate analysis (between two variables). All numeric data will be tested for normal distribution using Kolmogorov-Smirnov.
Univariate analysis will be done to see the average, distribution, and frequency of all variables/outcomes which include the participants' demographic information and MDVP parameters. MDVP parameters will be presented as mean score with its standard deviation (or median with range). Bivariate analysis will be done to evaluate the significance between occupational or non-occupational users to their MDVP parameters. Differences between groups will be assessed using independent samples t-test (parametric) or Mann-Whitney (non-parametric). If possible, multivariate analysis will also be conducted using Chi-Square or Fischer test depending on the data distributions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Occupational Voice Users
Workers who uses voice extensively during work falls under occupational voice users (e.g. singers, actors, radio announcer, teacher, translator, lawyer). The grouping were made based on references from The Union of the European Phoniatricians
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.
Non-occupational Voice Users
Those who didn't use voice extensively during work falls under non-occupational voice users (motorcycle drivers, daily labor, administrative workers)
