Sound and Communication


Book Description

In Hindu India both orality and sonality have enjoyed great cultural significance since earliest times. They have a distinct influence on how people approach texts. The importance of sound and its perception has led to rites, models of cosmic order, and abstract formulas. Sound serves both to stimulate religious feelings and to give them a sensory form. Starting from the perception and interpretation of sound, the authors chart an unorthodox cultural history of India, turning their attention to an important, but often neglected aspect of daily religious life. They provide a stimulating contribution to the study of cultural systems of perception that also adds new aspects to the debate on orality and literality.




Sound Communication in Fishes


Book Description

This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.




Animating Culture


Book Description

Long considered "children's entertainment" by audiences and popular media, Hollywood animation has received little serious attention. Eric Smoodin's Animating Culture is the first and only book to thoroughly analyze the animated short film. Usually running about seven or eight minutes, cartoons were made by major Hollywood studios--such as MGM, Warner Bros., and Disney--and shown at movie theaters along with a newsreel and a feature-length film. Smoodin explores animated shorta and the system that mass-produced them. How were cartoons exhibited in theaters? How did they tell their stories? Who did they tell them to? What did they say about race, class, and gender? How were cartoons related to the feature films they accompanied on the evening's bill of fare? What were the social functions of cartoon stars like Donald Duck and Minnie Mouse? Smoodin argues that cartoons appealed to a wide audience--not just children--and did indeed contribute to public debate about political matters. He examines issues often ignored in discussions of animated film--issues such as social control in the U.S. army's "Private Snafu" cartoons, and sexuality and race in the "sites" of Betty Boop's body and the cartoon harem. Smoodin's analysis of the multiple discourses embedded in a variety of cartoons reveals the complex and sometimes contradictory ways that animation dealt with class relations, labor, imperialism, and censorship. His discussion of Disney and the Disney Studio's close ties with the U.S. government forces us to rethink the place of the cartoon in political and cultural life. Smoodin reveals the complex relationship between cartoons and the Hollywood studio system, and between cartoons and their audiences.




Communication Acoustics


Book Description

In communication acoustics, the communication channel consists of a sound source, a channel (acoustic and/or electric) and finally the receiver: the human auditory system, a complex and intricate system that shapes the way sound is heard. Thus, when developing techniques in communication acoustics, such as in speech, audio and aided hearing, it is important to understand the time–frequency–space resolution of hearing. This book facilitates the reader’s understanding and development of speech and audio techniques based on our knowledge of the auditory perceptual mechanisms by introducing the physical, signal-processing and psychophysical background to communication acoustics. It then provides a detailed explanation of sound technologies where a human listener is involved, including audio and speech techniques, sound quality measurement, hearing aids and audiology. Key features: Explains perceptually-based audio: the authors take a detailed but accessible engineering perspective on sound and hearing with a focus on the human place in the audio communications signal chain, from psychoacoustics and audiology to optimizing digital signal processing for human listening. Presents a wide overview of speech, from the human production of speech sounds and basics of phonetics to major speech technologies, recognition and synthesis of speech and methods for speech quality evaluation. Includes MATLAB examples that serve as an excellent basis for the reader’s own investigations into communication acoustics interaction schemes which intuitively combine touch, vision and voice for lifelike interactions.

Communication Acoustics


Book Description

The communication channel, in communication acoustics, comprises of a sound source, a channel (acoustic and/or electric) and finally the receiver: the human auditory system, a complex and intricate system that forms the way sound is heard. Consequently, when developing techniques in communication acoustics, such as in speech, audio and aided hearing, it is significant to understand the time-frequency-space resolution of hearing. The book gives an introduction to the fields which concern some kind of communication channel having the human as listener in the end; the fields together are named as "communication acoustics". This book conveys to engineering students and researchers alike the relevant knowledge about the nature of acoustics, sound and hearing that will empower them to develop new technologies in this area from end to end getting a thorough understanding of how sound and hearing works. It converses the multidisciplinary area of acoustics, hearing, psychoacoustics, signal processing, speech and sound quality and is appropriate for senior undergraduate and graduate courses related to audio communication systems. It discusses the technologies and applications for sound synthesis and reproduction, and for speech and audio quality evaluation.
