Abstract

Aims: This study was carried to control and monitor the sound using LabVIEW software. Methods: The research was done using LabVIEW software, microphones, and data-acquisition card hardware. Environmental information collected as sound pressure level via microphones and then processed by the data-acquisition card hardware. The information is showed by software as a graph or plot in the next step. Results: This software includes front panel, back panel, and connector panel and with these panels, we can determine information such as various frequency weighting and time weighting. Also, can be specified the sound pressure level, sound amplitude, power spectrum, power spectral density, and other sound characteristics. 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, we can use this software to analyze and process sound and vibration as a monitoring system. © 2015 Forouharmajd F.
