The Role of Physiological and Acoustic Models in Explaining the Direction of Sound Change*
نویسنده
چکیده
The sounds of language change due to sociological, grammatical, physiological, and perceptual reasons. I will not be concerned in this paper with those changes due to sociological or grammatical factors, that is, those which are essentially unique to a given language at a given period in time. Rather, I will discuss those sound changes which have been observed in a wide variety of unrelated languages and which therefore undoubtedly reflect some universal tendencies of human sound systems—tendencies which must originate in the common articulatory and perceptual mechanisms used by human speakers and listeners.

Acoustic propagation analysis in the front of saline water mass in the Gulf of Aden
Background and Objectives: Influence of water mass on sound propagation in the Gulf of Aden underwater acoustics used for communication, navigation and identification of objects by both humans and marine mammals and for investigating the detrimental effects of anthropogenic activities (e.g. pile driving, seismic survey and ships) on marine animals. The Gulf of Aden presents a unique ecosystem t...
متن کاملEffect of porosity on the characteristics of underwater acoustic sound absorbers using theoretical models
Porous materials have good acoustic damping characteristics over a wide frequency range. As for sound waves, many small-scale pores in the coating materials can convert underwater-coating to rough surfaces. The main property of porous absorbents is their resistance against incident sound wave that leads to damping effect. From a physical point of view, damping occurs due to friction between flu...
متن کاملInvestigation on acoustic behavior of acoustic porous absorbers to absorb sound energy and transmission loss index
In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.

In this paper, a novel analytical method was developed based on statistical energy analysis framework to evaluate sound transmission loss through ventilated windows. The proposed method was compared to numerical and analytical models available in the literature. Results showed the success and advantage of the proposed model in predicting the acoustic performance of the ventilated window and the...
متن کاملExperimental study and modelling of date palm fibre composite acoustic behaviour using differential evolution algorithm
Background and aims: In recent years, in most countries of the world, the provision of a calming environment without disturbing noise has become a need, which has subsequently led to significant growth in noise control techniques. It is now well documented that prolonged over-exposure to the excessive levels of environmental noise not only induces disabling hearing impairment but also contribut...
