Christopher Sittl

Christopher Sittl is a Researcher at the Chair of Vibroacoustics of Vehicles and Machines within the Department of Engineering Physics and Computation at the TUM School of Engineering and Design, Technical University of Munich. Pursuing an External PhD, his work focuses on developing efficient computational methods for acoustic optimization in automotive applications.

His research interests span computational acoustics, vehicle noise control, and advanced numerical methods:

• Computational Acoustics
• Vehicle Acoustics and Noise Optimization
• Boundary Element Method applications
• Finite Element Method for vibroacoustic problems
• Matrix-Padé-via-Lanczos Method implementation
• Sound quality engineering for automotive powertrains

Sittl's research addresses the computational challenge of solving large linear systems in acoustic scattering tasks, moving beyond traditional frequency-by-frequency approaches to develop more efficient Padé-approximation methods applicable across frequency ranges. His work bridges theoretical numerical methods with practical automotive engineering needs, particularly in creating customer-pleasant noise profiles rather than merely minimizing sound pressure levels.

His primary publication demonstrates application of Krylov subspace methods for efficient acoustic transfer function solutions. Collaborating with Ostbayerische Technische Hochschule Regensburg, Otto von Guericke University of Magdeburg, and CHP Messtechnik GmbH, his research contributes to the department's focus on computational vibroacoustics and automotive noise control.
