In my aesthetic universe, the danfo bus is a stable visual sign around which I assemble acoustic references to Lagos.
In our analysis, we use Moctesuma to simulate the reference acoustic field (in the MMP) and to access the acoustic parameters of the environment such as horizontal wavenumbers, group velocities, and mode excitation factors signs.
Speech sounds have been described and classified both from an articulatory viewpoint, in terms of how they are produced, and from an acoustic viewpoint, by reference to the resulting sound waves (their frequencies, amplitudes, and so forth).
The reference acoustic field needed for depth localization is simulated with the new realistic propagation modelMoctesuma.
The reference acoustic field needed for depth localization is simulated with a new realistic propagation model.
The spatial resolution and penetration depth of X-rays and focused acoustic beams with reference to residual stress measurements are discussed.
Both methods require a reference acoustic field (replica field) to be compared, generally by correlation techniques (building and maximizing an objective function), with the real acoustic field recorded on receiver(s).
Each layer is represented by a two-by-two traveling pressure wave transfer matrix which relates the forward and reverse pressure waves on one side of the layer to the pressure waves on the opposite face, where each face is assumed to be in contact with a domain of arbitrary reference acoustic impedance.
It has been used to study call categorization and the detection of unreliable signalers [Cheney & Seyfarth, 1988], the discrimination of different individuals within a group of kin [Rendall et al., 1996], the importance of acoustic similarity and "external reference" [Hauser, 1998a], and the discrimination of acoustically similar call types [Fischer, 1998; Fischer et al., 2001b].
The acoustic mismatch between clean reference features and noisy test features caused by the environmental noise produces a statistical difference between their corresponding probability density functions (PDFs) [21].
