Generation and analysis of an acoustic radiation pattern database for forty-one musical instruments.
A database of acoustic radiation patterns was recorded, modeled, and analyzed for 41 modern or authentic orchestral musical instruments and can be used both for studying the radiation of musical instruments itself and for the implementation of radiation patterns in room acoustical simulations and auralization in order to obtain a spatial excitation of the room closer to reality.
Variable Directivity for Platonic Sound Sources Based on Spherical Harmonics Optimization
Sound sources for measurements in room acoustics are of omni-directional type, in general. With respect to auralization applications, an omni-directionally measured room impulse response may not be
Measuring Directivities of Natural Sound Sources with a Spherical Microphone Array
Ambisonics recording technique is based on a small microphone array, whose microphones are placed as close as possible to each other, but it is the spatial attributes of the sources outgoing spherical-like wave that should be recorded, leading to the need of a larger microphone array that completely encompasses the sound source.
About just noticeable differences for aspects of spatial impressions in concert halls
In order to describe the acoustics of enclosed spaces and to quantify the properties of sound fields, single number parameters are commonly used. These are calculated from impulse responses which
Variable Source-Directivity Using Dodecahedron-Loudspeakers
For room‐acoustical measurements dodecahedron loudspeakers are commonplace to achieve a uniform directivity. Therefore all transducers are fed with the same signal. If the signals for the twelve
Musical instrument recording for building a directivity database
An important characteristic of the sound of musical instruments is their tonal color. It describes the spectral intensity of their sound radiation which is different for any angle of radiation. Sound
Repeatability and Reproducibility of In Situ Measurements of Sound Reflection and Airborne Sound Insulation Index of Noise Barriers
In Europe, in situ measurements of sound reflection and airborne sound insulation of noise barriers are usually done according to CEN/TS 1793-5. This method has been improved substantially during the
