Comparison of Aircraft Noise Models with Flyover Data

A research paper focuses on low-noise flight procedures and low-noise aircraft design. It reveals that application of scientific or comprehensive noise-prediction tools becomes essential to meet these objectives. It states that the Parametric Aircraft Noise Analysis Module (PANAM) serves as an integration framework to exploit and incorporate existing and future DLR capabilities in airframe and engine noise modeling, vehicle design, flight procedures, air traffic management, and evaluation of noise effects. Specialists from individual disciplines can use PANAM to evaluate their individual technologies on a system level and thus assess the overall impact on vehicle performance and the environment. The individual airframe noise components are modeled with DLR in-house approaches. Engine noise models are based on available and published solutions.
