A database of acoustic radiation patterns was recorded, modeled, and analyzed for 41 modern or authentic orchestral musical instruments. The generation of this database included recordings of each instrument over the entire chromatic tone range in an anechoic chamber using a surrounding spherical microphone array. Acoustic source centering was applied in order to align the acoustic center of the sound source to the physical center of the microphone array. The acoustic radiation pattern is… 
The Acoustical Effect of Musicians' Movements During Musical Performances
Acoustic musical instruments act as dynamic sound sources communicating the expressive intentions of a performer to the audience in a dedicated spatial environment. From an acoustical point of view,
Sound power and timbre as cues for the dynamic strength of orchestral instruments.
TLDR
In a series of measurements and statistical analyses, a comprehensive picture of the acoustical manifestation of "musical dynamics" with respect to sound power and timbre for all standard orchestral instruments is delivered.

For the quality of model-based, virtual acoustic environments, not only the room acoustic simulation but also the quality and suitability of the source material play an important role. An optimal

It is shown that a gold-plated device mounted on a tenor saxophone, forming a small bridge between the mouthpiece and the S-bow, can change two characteristics of the radiated sound: (1) the radiated
The sound radiation of musical instruments at the transition from near field to far field
Musical instruments have complex radiation patterns that vary at different points of observation relative to the source. Usually directivity patterns are measured at one specific distance in the far

TLDR
It is demonstrated that imposing the signature of the directivity that is obtained at a given distance on a spherical wave allows for all interpolation that is required for obtaining a complete spherical harmonic representation of the source's directivity, i.e., a representation that is viable at any frequency, in any direction, and at any distance.

Repeatability and realism are both highly important goals in concert hall perceptual studies, but it is hard to satisfy both simultaneously. Auralization from room impulse response (RIR) measurements
State-space modeling of sound source directivity: An experimental study of the violin and the clarinet.
TLDR
Techniques are proposed for modeling and simulating directivity profiles on perceptual frequency axes with alternatives for representing directivity on a per-vibration-mode basis while incorporating relative phase terms or by reduced-order efficient representations.
Timbre Discrimination for Brief Instrument Sounds
TLDR
An adaptive procedure is applied to investigate the effect of musical training on individual thresholds for instrument identification, and it is suggested that the test subjects adjust the weightings of the perceptual dimensions of timbre according to different degrees of acoustic degradation of the stimuli.

TLDR
This work presents a source centering algorithm that operates on plane sections and aims to achieve a convex objective function on every plane section, and the results are shown to be more convex than the previous algorithms for sources with higher-order radiation pattern, usually at higher frequencies.
Measuring Directivities of Natural Sound Sources with a Spherical Microphone Array
TLDR
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.

TLDR
Pairs of measured and averaged directivities have been used both for room simulation comparisons and as a basis for listening experiments with auralizations to show that some changes produced by directivity variations can be perceived by the listener.
