How does sound in sound healing work? This article explores qualities and energetics of sound. SOUND HAS RESONANCE. Resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate (move or swing) Some objects have two or more resonant frequencies. Resonance occurs when an object’s movements (oscillations) are increased by the matching vibrations of another object. Everything in the universe vibrates, which means everything has a resonant frequency whether we can audibly perceive it or not, such as dog whistles, wi-fi, radio towers. When taken in alignment with the concept of sound, every organ, bone and tissue in our body has a resonant frequency. When taken to another level, understand that a conscious being is more than a combination of organs, bone and tissues. A conscious being has thoughts, feelings, and emotions. Therefore the resonant frequency of an individual in combination with the resonance of a physical body and consciousness create a compositional frequency and harmonic resonance that has the ability to attract others, as well as affect others in a positive or negative way. SOUND HAS FREQUENCY. Frequency is the number oscillations (vibrations or waves) per unit of time. It is measured in cycles per second called Hertz. The slower the vibration the lower the frequency. The faster the vibration, the higher the frequency. (we can see this physically manifest on the length of a pendulum chain - the shorter the chain the faster the pendulum response) The speed at which sound travels depends on the media through which the sound is traveling. Sound travels 4x faster in water than in the air, so the body, made mostly of water is an excellent sound resonator. SOUND HAS RHYTHM, this is to say that there is a regular pattern of beats and regular recurring patterns of activity. (such as a heartbeat) These patterns are formed from stress and unstressed actions. This is another reason why sounds can calm and stabilize the body. SOUND HAS ENTRAINMENT. Entrainment is an action that causes something to happen, it draws something in and moves it along in the flow. Solid particles, air bubbles, or liquids dropped into a moving fluid are carried along. With entrainment, the body cells have the ability to communicate. Healthy cells can transform unhealthy cells. SOUND HAS VIBRATION. Vibration is the process of movement, which in effect can communicate feelings and thoughts from one to another as well as creates the atmosphere of a place or a situation. We observe this when we enter certain buildings, a church or temple feels much differently than a busy office. SOUND HAS TONE/TIMBRE. Tone is a measure of the quality of a sound wave. Timbre is the perceived quality of any sounds’ multiple frequencies changing through time. This explains why some sounds stimulate positive or negative memories, as well as the importance of soundtracks in the movies for example.
