Amplitudes Upon Reflection in Acoustical Experiments
This short note describes some simple acoustical wave experiments that explain the physics of reflection and transmission coefficient formulae for normal incidence P-waves. The experiments help us to understand the mathematical expressions for the reflection and transmission coefficients for displacement and pressure that are frequently used in seismology. Figure 1. The figure shows a boundary ...
متن کاملEmotions and speech: some acoustical correlates.
This paper describes ome further attempts to identify and measure those parameters in the speech signal that reflect the emotional state of a speaker. High-quality recordings were obtained of professional "method" actors reading the dialogue of a short scenario specifically written to contain various emotional situations. Excerpted portions of the recordings were subjected to both quantitative ...
متن کاملFrankenstein Classiiers: Some Experiments
We present some empirical results on the use of two methods for integrating diierent classiiers into a hybrid classiier that should perform better than each of its constituent classiiers. The main point of these methods is that instead of combining full classiiers, they combine pieces of them. One of the methods is based on ROC analysis; the other is based on augmenting the data with features d...
متن کاملSome Aspects of Analysis of Dolphins’ Acoustical Signals
Dolphins produce various types of sounds in a wide range of frequencies. Characteristics of some sounds till now have not been correctly registered, that influenced on interpretation of their functions. Studying of the characteristics and functions of dolphins’ acoustical signals is the purpose of the present work. In this work the acoustical signals of two dolphins (Tursiops truncatus) were re...
متن کاملThermo acoustical studies on some electrolytic solvent mixtures at 303
Ultrasonic velocity of Benzene with Tolune and O-Xylone with various concentration at 303 K. The internal pressure and some parameters are calculated from the measured sound velocity, density and viscosity. The results were discussed in terms of ion-solvent and solvent-solvent interactions.
