“…The true situation may perhaps be summarized by Fig. 13, taken from Mathews, et al [72] which compares the measured maximum sound pressure level with the predictions of four proprietary methods. Not one is even able to predict the trend with speed.…”

“…The conservation in the acoustic energy is subject to some controversy and a clear conclusion on this has not been observed in previous studies 5,8 . Consequently, the introduction of that third term in the energy balance is not seen as an evident loss of energy mechanism to be correlated, but rather as a 'soft' energy conservation imposition.…”

“…Figure 9 shows the overall sound power level from the LPT of eight different engines scaled to the same diameter and plotted as a function of turbine loading. Turbine loading is an LPT noise correlation parameter which is used in several empirical LPT noise predictions [4][5][6]. As the figure shows, there is more than a 30 dB spread in the data.…”
