SUMMARY
The discussion centers on the calculation of sound pressure levels using the formula RL = 20log(Vrms) - OCV, specifically addressing the value of OCV at -211 dB re μPa/V. It is confirmed that -211 dB is an acceptable input for the equation without conversion to standard units, as it serves as a reference point. The logarithmic scale is emphasized, with 120 dB re 20 μPa being a standard reference for sound pressure levels. Additionally, the importance of frequency weighting in sound measurements is highlighted, particularly around 2 to 4 kHz.
