This noise may have both tonal and random components and is strongly dependent on the way that the fan is placed in the unit and on how close its operation is to the design operating point.

The knowledge gained in this work provides a basis for improved fan source specification in overall aircraft system noise studies.
Therefore, the noise observeda way from a low pressure axial flow fan is mostly the turbulent noise.

Furthermore the acoustic output at the presence of parameter variations provides guidelines for the design-to-noise of fan components.
The results of this study have an important bearing on estimating the noise characteristics of new fan designs from scaling the measured characteristics of previously tested fans.
The results indicate the limits of maximum noise reduction which manufacturers may expect using existing fan designs and also indicates the methods for achieving maximum noise reduction for these configurations.
In addition, new sources caused by the interaction between the stationary distortion and the fan blades appear and contribute to the inlet noise.

Their performance is on par with previously presented GPU implementations of noise, they are very convenient to use, and they scale well with increasing parallelism in present and upcoming GPU architectures.
