Rebecca Lazarides,Angela Ittelunity. Acoustics is important in design because many machines have to meet noise and vibration specifications. It is good engineering practice to design quiet machinery since, all other things being equal, the quiet machine is preferred by the customer to the noisy one. Noise is often an indicator o

Andreas Beelmannsm, thus allowing for the description of mechanic and acoustic systems in electrical terms. This is convenient for engineers and scientists who are knowledgeable in the analysis and synthesis of electric networks. The basics of electromechanic and electroacoustic analogies are introduced, and releva

Bärbel Kracke,Ada Sassesed by 350 million people in India, Bangladesh, and the Bengali diaspora. The book analyzes the real speech of selected native speakers of the Bangla dialect to ensure that a proper acoustical database is available for the development of speech technologies. The acoustic data presented consists of a

These cases, however, play an important role as model systems, as a first approximation to real physical problems, in estimation of the range of applicability of various a

Sandra Fleischer,Daniel Hajokideal model can occur. The medium’s boundaries could be nonhorizontal. The sound velocity and other medium parameters may depend on horizontal coordinates. Below we shall assume, however, that such deviations from ideal stratifications are small in some sense. This assumption is quite realistic in m

Julia Dietrichion, however, it is important to take into account that the sound source is located at a finite distance from the receiver as well as from the boundaries. The most simple example of this is the classical problem about the field of a point source in the presence of an interface between two homogeneou
