Some spatial analysis of the room impulse response

Journal of the Acoustical Society of America, 2015
The room impulse response (RIR) and measures derived from it have been a powerful tool for room characterization. Traditionally, these measures are based on time domain characteristics like reverberation time or clarity. By recoding a group of RIRs with microphone arrays, one can add the spatial dimension to the RIR.

Self-similar analysis of the room impulse response

The Journal of the Acoustical Society of America, 2006
Important information of the room acoustic characteristics is contained in the room impulse response. We analyze the time-space correlation of the impulse response by the self-similarity method. The room impulse response is divided into the frame of the length of the fixed time. Attractors are composed by affine transformation of each frame.

Impulse Response Analysis of Ocean Acoustic Propagation

1991
An intuitive picture of ocean sound channel propagation from point sources is developed in terms of impulse response. The entire wavefront is described for fixed times that are appropriate for propagation to ≈ 1000 km. The wavefront characteristic that allows determination of the source depth is shown to be the distance between the two distinct ...

Feynman diagram analysis of transducer impulse response

The Journal of the Acoustical Society of America, 1983
Transducer impulse response is analyzed by introducing two novel elements. First, the usual equivalent circuit of the transducer is replaced by a simple reentrant transmission line configuration. Second, a Feynman diagram method is applied which involves tracing the exciting signal through all possible pathways to the time and place of observation. The

Visual parameter analysis for impulse response

Jedes Lautsprecher- und Mikrofon-Setup, das ein Benutzer konfigurieren kann, hat einen einzigartigen Klang. Mit IR-Dateien können Sie die Eigenschaften dieser Konfigurationen digital aufzeichnen und dann auf ein Gitarrensample anwenden. Das Ergebnis ist eine Aufnahme, die so klingt, als wäre sie mit der oben genannten Konfiguration aufgenommen worden ...

Diffuseness and intensity analysis of spatial impulse responses

The Journal of the Acoustical Society of America, 2008
Spatial impulse responses, meaning responses measured with a microphone grid, were measured in seven concert halls. The microphone array consisted of 12 omni-microphones, enabling a construction of three intensity pairs (in x, y, and z directions) with 1 cm spacing and three intensity pairs with 10 cm spacing.

The Sinc Interpolation in the Impulse Response Function Analysis

[Proceedings] IGARSS '92 International Geoscience and Remote Sensing Symposium, 2005
sin(x) The - (sinc) interpolation is commonly used in resampling SAR data centered around a point target to obtain the interpolated impulse response function to be analyzed. Detected SAR data are output from correlation processor in either amplitude or intensity format.

Impulse-Response Analysis in a Simple DSGE Framework

Ovidius University Annals, Economic Sciences Series, 2010
This paper intends to perform a simple impulse-response analysis on the Romanian economy with the help of a DSGE model. The DSGE methodology has its origins in the Real Business Cycle Theory, and recently it became quite popular, especially after the seminal contribution of Smets and Wouters ([8]).

[Analysis of impulse response of rectangular ultrasound transducer].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2002
A new expression for calculating the impulse response of rectangular pistonlike transducers, proper to any points of acoustic field, is presented. The radiated field of ultrasound transducer can be analyzed using impulse response method, avoiding paraxial and farfield approximation.
