Essay on psychoacoustics

In the realm of psychoacoustics, the terms music, sound, frequency, and vibration are interchangeable, because they are different approximations of the same essence. The study of psychoacoustics dissects the listening experience. Currently, however, there is renewed interest in sound as vibration.

Why choose this course?

An important distinction is the difference between a psychological and a neurological perception. A song or melody associated with childhood, a teenage romance, or some peak emotional experience creates a memory-based psychological reaction. There is also a physiological response to sounds, however.

Slightly detuned tones can cause brain waves to speed up or slow down, for instance. Additionally, soundtracks that are filtered and gated this is a sophisticated engineering process create a random sonic event. It triggers an active listening response and thus tonifies the auditory mechanism, including the tiny muscles of the middle ear.

As a result, sounds are perceived more accurately, and speech and communication skills improve. While a psychological response may occur with filtered and gated sounds, or detuned tones, the primary effect is physiological, or neurological, in nature. Research on the neurological component of sound is currently attracting many to the field of psychoacoustics.

A growing school of thought — based on the teachings of the Dr. Alfred Tomatis — values the examination of both neurological and psychological effects of resonance and frequencies on the human body.

Thanks to the ground breaking findings of Dr. Tomatiswe have come to understand the extraordinary power of the ear. After birth, sound is to the nervous system what food is to our physical bodies: Food provides nourishment at the cellular level of the organism, and sound feeds us the electrical impulses that charge the neocortex.

Anything that moves has a vibration.

What you will study

Though invisible, every aspect of our material world at the atomic level moves constantly. Wherever there is motion, there is frequency. Though inaudible at times, all frequencies make a sound. All sounds resonate and can affect one another.

In the spectrum of sound — from the movement of atomic particles to the sensory phenomenon we call music — there is a chain of vibration: All atomic matter vibrates.

Frequency is the speed at which matter vibrates. The frequency of vibration creates sound sometimes inaudible. Sounds can be molded into music. This chain explains the omnipresence of sound. Resonance is the single most important concept in understanding the constructive or destructive role of sound in your life.

Entrainment, sympathetic vibration, resonant frequencies, and resonant systems all fall under the rubric of resonance. This can have many different effects — some subtle and some not so.

From iceburgs to airport construction to the human body, soundwaves have the capacity to alter, to actually shift frequency. Simply put, sound is a powerful — yet often ignored — medium for change. Another fascinating and important aspect of resonance is the process of entrainment.Honors Honors Program in the School of Biological Sciences.

Introduction and Overview. This research defines and outlines the ego death theory, as a new systematic research framework and paradigm. The ego death theory holds that the essence and origin of religion is the use of visionary plants to routinely trigger the intense mystic altered state, producing loose cognitive-association binding, which then produces an experience of being controlled by.
