Sound is one of the types of waves that can be felt by the sense of hearing. In physics, the definition of sound is something that is produced from objects that vibrate. Objects that produce sound are called sound sources. The sound source will vibrate the molecules into the air around it. Sound is mechanical compression or longitudinal waves that propagate through the medium. This medium or intermediate agent can be liquid, solid, gas.

Sound is one of the types of waves that can be felt by the sense of hearing (ears). In physics, the definition of sound is something that is produced from objects that vibrate. Objects that produce sound are called sound sources. The sound source that vibrates will vibrate the molecules into the air around it. Sound is mechanical compression or longitudinal waves that propagate through the medium. This medium or intermediate agent can be liquid, solid, gas. So, sound waves can propagate for example in water, coal, or air. Most sounds are a combination of various vibratory signals composed of harmonic waves, but pure sound can theoretically be explained by oscillating vibrational speed or frequency measured in Hertz (Hz) vibration units and amplitude or loudness of sound with measurements in decibels (dB). The effect sounds can have on us humans is simply astounding. While everyday life becomes stressful, overcrowded and increasingly hectic, we seek ways for inner peace and balance. The power of music, felt through overtone-rich sound therapy and sound massage, can be a solution. No matter how much scientific explanation is behind it, healing through music remains fascinating, even magical. This paper introduces a new field called cymatics and sound healing with their plausible impact to spirituality and consciousness research.

Artificial Intelligence and Multimodal Signal Processing in Human-Machine Interaction presents an overview of an emerging field that is concerned with exploiting multiple modalities of communication in both Artificial Intelligence and Human-Machine Interaction. The book not only provides cross disciplinary research in the fields of multimodal signal acquisition and sensing, analysis, IoTs (Internet of Things), Artificial Intelligence, and system architectures, it also evaluates the role of Artificial Intelligence I in relation to the realization of contemporary Human Machine Interaction (HMI) systems.Readers are introduced to the multimodal signals and their role in the identification of the intended subjects, mental state and the realization of HMI systems are explored, and the applications of signal processing and machine/ensemble/deep learning for HMIs are assessed. A description of proposed methodologies is provided, and related works are also presented. This is a valuable resource for researchers, health professionals, postgraduate students, post doc researchers and faculty members in the fields of HMIs, Brain-Computer Interface (BCI), Prosthesis, Computer vision, and Mental state estimation, and all those who wish to broaden their knowledge in the allied field. - Covers advances in the multimodal signal processing and artificial intelligence assistive HMIs - Presents theories, algorithms, realizations, applications, approaches, and challenges that will have their impact and contribution in the design and development of modern and effective HMI (Human Machine Interaction) system - Presents different aspects of the multimodal signals, from the sensing to analysis using hardware/software, and making use of machine/ensemble/deep learning in the intended problem-solving

An overview of the pioneering work done by Dr. Hans Jenny with audible vibration on various substances. His research had led to speculation about the origin of matter and its relation to vibration and sound.

A practical and accessible guide to sound healing therapies • Explores tools such as tuning forks, gongs, singing bowls, drumming, chakra chants, and angelic vibrations • Provides simple practices such as humming, vowel toning, and affirmations that you can begin using right away for self-healing • Explains how sound therapy triggers self-healing mechanisms and offers a non-invasive way to permeate every cell of the body with healing intentions All sound and vibration affect us. From the moment of birth--even in the womb--every word, thought, or sound we encounter is important and powerful, nourishing or toxic. When we understand the powerful effects of sound and vibration, we can consciously apply them for our health and well-being. In this practical and accessible guide, Erica Longdon explains the therapeutic and healing impact of sound, frequency, and vibration on the body, mind, and spirit. She shows how sound therapy triggers the body’s natural self-healing mechanisms and offers a non-invasive way to permeate every cell of the body with healing intentions. She presents a wide range of sound-healing methods and vibrational practices and explores tools such as tuning forks, gongs, singing bowls, drumming, chakra chants, and angelic vibrations as well as cymatics--the study of wave phenomena, which makes sound visible. She explains how to use different sound healing methods and offers instructions both for self-treatment and as preparation if you go see a sound therapist. She reveals how each of us has a sound healing tool at our disposal--our own voice--and provides simple practices and exercises such as humming, vowel toning, and affirmations that you can begin using right away for self-healing. She also explores the power of silence and how even our inner vibrations--thoughts and intentions--affect us sonically and can be used for vibrational healing. Offering a natural way to treat pain and illness, this guide gives you the tools to connect with your inner healer, restore balance and harmony, and harness the power of vibration for sound health.

In the 18th century, Chladni developed the technique of drawing a violin bow across a metal plate of sand and observing the patterns that formed. In this title, Lauterwasser extends the idea to more complex and moving sounds in water, ranging from pure sine waves to music by Beethoven, Stockhausen and overtone chanting.
