Background: One of the harmful factors in the field of occupational health is exposure to noise and vibration. Better control of hazardous agent requires robust and efficient software that prevents the increased risk with real-time control. Therefore, this study was conducted with the aim of setting a system using labview software to monitor the sound momently.Methods: The research is an experimental study that was doing by using Labview software, microphones and data acquisition card. Environmental information collected as sound pressure level via microphones and then processed by the sound analyzes card. The results will be showed by software as a graph or plot in the next step.Findings: This software is including the front panel, back panel and connector panel that with these panels can be determined information such as various frequency weighting and time weighing. After entering the information, the sound pressure level, sound amplitude, power spectrum, power spectral density and other sound characteristics can be specified.Conclusion: Labview programming capabilities in the field of sound can be referred to the measurement of sound, frequency analysis and sound control that actually the software acts like a sound level meter and sound analyzer. According to the mentioned features, this software is suitable to analyze and process sound and vibration as a monitoring system. Key Words: Labview Software, Sound Amplitude, Power Spectrum, Frequency Weighting
