Properties of sound

Acoustic properties of foams, such as macroscopic transports and sound absorption, are significantly influenced by their local morphology. The present paper develops a polynomial chaos expansion (PCE)-based surrogate model for characterizing the microstructure-properties relationships of acoustic monodisperse foams.

In this paper, we present a definition of fuzzy multivalued dependencies in fuzzy databases with linguistic data based on similarity relation which is built by partitioning the domain of attribute values corresponding to an appropriate hedge algebra. Some properties of fuzzy multivalued dependencies are studied. Finally, the set of inference rules is shown to be sound and complete for a relation scheme class when it satisfies some specified conditions.

After completing this unit, you should be able to: Describe the structure and general function of the outer, middle, and internal ears; describe the sound conduction pathway to the fluids of the internal ear, and follow the auditory pathway from the spiral organ (of Corti) to the temporal cortex; explain how one is able to differentiate pitch and loudness, and localize the source of sounds;...
