Already in ancient times, the goal existed to design appropriate environments to transport acoustic signals from a sound source to an audience. Strongly connected to this is the interest to understand room acoustic effects and, in the best case, to accurately predict them. This is of particular relevance today in prestigious projects such as the […]

Soundscape studies are showing the importance and the benefits regarding the sonic the environment in our daily lives. The soundscape paradigm shift highlights not just negative aspects, common on environmental noise studies, but also how the sonic environment can be recovering to the welfare of communities. Thinking on the valuation of settings, past studies focused […]

Hearing loss (HL) has multifaceted negative consequences for individuals of all age groups. Despite individual fitting based on clinical assessment, consequent usage of hearing aids (HAs) as a remedy is often discouraged due to unsatisfactory HA performance. Consequently, the methodological complexity in the development of HA algorithms has been increased by employing virtual acoustic environments, […]

Regardless of the field, measurements are essential for the validation of theories and for making well-founded decisions. A criterion for the validity and comparability of measured values is their uncertainty. The "Guide to the Expression of Uncertainty in Measurement" (GUM) provides a standardized framework for determining and interpreting measurement uncertainty. In room acoustic measurements, the […]

Building acoustics auralization is used to assess the perceptual aspects of sound transmission in built environments to provide the guidelines for architectural constructions and to evaluate the noise effects on humans. These noise effects have a negative influence on daily-life activities and create disturbances in physical and metal work. These disturbances are present within the […]

Auralisation describes the process of generating and presenting audible sound using computer programs and audio hardware. Since the result is perceived naturally by the human's auditory system, a demonstration by means of auralisation is easily comprehensible and does neither require background knowledge nor expertise. Producing auralisation under real-time constraints increases the implementation demands significantly. Real-time […]

Die Notwendigkeit gesetzlicher Regulierungen des Außengeräuschs von Personenkraftwagen (PKW) resultiert aus dem Einfluss von Lärm auf das menschliche Wohlbefinden. Die Messung von PKW-Außengeräuschen wird unter genormten Bedingungen nach gesetzlichen Regulierungen als sogenannte Vorbeifahrtmessung durchgeführt. Die jüngste gesetzliche Norm der „Economic Comission of Europe“ (ECE) ist die ECE R51.03. Die Motivation der vorliegenden Arbeit basiert auf […]

is thesis addresses key challenges in acoustics applications like troubleshooting, product optimization, and sound source modeling, focusing on the localization and characterization of sound sources using Beamforming techniques and an improved regularization of inverse methods. Traditional Beamforming methods, while effective in identifying main radiating sources, are limited by the array size and density, which affects […]
