Kohnen: Combining Reproduction Techniques for Room Auralizations

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Spatial auditory information allows humans to separate sources from each other. Furthermore, source localisation can steer the focus towards events that are not in sight. 3D sound is hence an important feature of human hearing. To investigate the particular effects of sound perception, a controlled reproduction of spatial sound is needed in order to recreate […]

Schäfer: Real-time auralization of aircraft noise considering curved sound propagation

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Aircraft are one of the major noise sources affecting residents close to airports. Classical metrics for noise assessment are usually derived from energy-based quantities, such as known from noise maps. Thus, they only consider human perception in a very basic manner. To investigate the impact of aircraft noise in a more accurate way, it is […]

Struck: Simulated Free Field Measurements

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Time selective techniques that enable measurements of the free field response of a loudspeaker to be performed without the need for an anechoic chamber are presented. The low frequency resolution dependent room size limitations of both time selective measurements and anechoic chambers are discussed. Techniques combining signal processing and appropriate test methods are presented enabling […]
