The OROS Sound Level Meter (OVA Overall Acoustics) is a software module designed for real-time, multichannel sound level measurement and analysis. It complies with IEC 61672 and related standards, ensuring accurate and standardized results for professional acoustic testing. The software supports up to three RMS detectors and one true peak detector per channel, with selectable time filtering and weighting (A, C, Z). It features a high-pass filter, large memory capacity (up to 100,000 points per channel), and is suitable for both laboratory and field environments. The module integrates seamlessly with OROS hardware and the NVGate platform, providing a user-friendly interface for setup, acquisition, and analysis of sound level data.
