Abstract—In the field of acoustics, noise investigations involving regulated measurements, this requires sophisticated and expensive equipment and obtaining data sets for subsequent analysis becomes very laborious and complicated. We used a virtual instrument computer (PC) and appropriate software to simulate asound level meter. This becomes a huge advantage in the design, cost and versatility of the instrument, since its functions and parameters can be easily redefined by changes in the programmed instructions,Furthermore, and this method avoids a redesign of a physical circuit. Virtual instrumentation is an indispensable tool to study, measure and evaluate complex conditions, such as acoustic spaces. In this work, the design and implementation of a sound level pressure meter in a virtual instrumentation scheme is presented. The system was implemented with Matlab and instrumentation software. The implemented noise measurement system presents a friendly interface to the user via a GUI and reduces time and costs in the determination of environmental noise measurements quite reliably.
