This document presents a thorough analysis of the whine characteristics observed in the 70th Band (1968-1972) and the 96th Band (1994-1998). It focuses on the measurement of output whine levels using the BSM "ONP" methodology. Emphasis is placed on achieving a target minimum whine level of -15 dB with an acceptable dynamic range of -6 dB. Data findings and graphical representations support the assessment of noise levels and performance across both bands, providing insights into their acoustic behavior over time.
