Eliminating wind noise contamination of wind turbine noise amplitude modulation ratings - first validation (2017)
Presentation / Conference
von Hünerbein, S., Kendrick, P., Kerscher, M., & Bradley, S. (2017, July). Eliminating wind noise contamination of wind turbine noise amplitude modulation ratings - first validation. Presented at The 24th International Congress on Sound and Vibration (ICSV24), London, UK

Microphone wind noise can corrupt outdoor measurements and recordings. It is a particular problem for wind turbine measurements because these cannot be carried out when the wind speed is low. Previous studies simulated the effect that microphone wi... Read More about Eliminating wind noise contamination of wind turbine noise amplitude modulation ratings - first validation.

Extended simulations of wind noise contamination of amplitude modulation ratings (2017)
Presentation / Conference

Coded signals: a challenge for acoustic wind profiling (2008)
Presentation / Conference
von Hünerbein, S., & Bradley, S. (2008, November). Coded signals: a challenge for acoustic wind profiling. Presented at 156th Meeting: Acoustical Society of America, Miami, FL, USA

Use of coded signals for acoustic wind profiling presents special challenges because the scattering mechanism is highly bandwidth sensitive. We outline the physical principles involved and show that the signal coding methods commonly used for underwa... Read More about Coded signals: a challenge for acoustic wind profiling.
