Influence of Model Detail Level on the Prognosis Quality of the Perceived Sound of an Electrified Passenger Car Powertrain Open
Complex and resource intensive multi-physical models which integrate the domains of electrotechnical, structural dynamics and acoustics are needed to predict the noise, vibration and harshness (NVH) behavior of an electric passenger car dr…

Measurement Uncertainty of the Room Acoustic Clarity Index Open
Measured room impulse responses are inherently uncertain like all measured quantities. This input uncertainty naturally propagates to derived metrics such as room acoustic single number quantities. Based on the framework provided by the Gu…

SCaLAr – A surrounding spherical cap loudspeaker array for flexible generation and evaluation of virtual acoustic environments Open
Introduction : Surrounding spherical loudspeaker arrays facilitate the application of various spatial audio reproduction methods and can be used for a broad range of acoustic measurements and perceptual evaluations. Methods : Installed in …

Sound power and timbre as cues for the dynamic strength of orchestral instruments Open
In a series of measurements, the sound power of 40 musical instruments, including all standard modern orchestral instruments, as well as some of their historic precursors from the classical and the baroque epoch, was determined using the e…

A Database of Anechoic Microphone Array Measurements of Musical Instruments Open
A collection of 3305 single notes of 41 musical instruments of different historical periods was recorded and analyzed. The database includes the instrument recordings, radiation patterns (directivities), and audio features such as the soun…

Loudspeaker Crossover Design (from analog to digital) Open
Loudspeaker systems are quite complex devices and considered ‘musical instruments’ for many HiFi-enthusiasts. However, from the technical point of view the description of an optimal loudspeaker seems to be simple: the reproduction of any e…

Generation of a reference radiation pattern of string instruments using automatic excitation and acoustic centering Open
Radiation patterns of musical instruments are important for the understanding of music perception in concert halls, and may be used to improve the plausibility of virtual acoustic systems. Many attempts have been performed to measure the s…
