Acoustics – The Science of Sound.

Acutonics – Acutonics is an energy-based approach to healing that uses vibrations and the sound of precision-calibrated planetary tuning forks. This effective non-invasive methodology works with vibratory energy created through sound.

Auditory Canal – is also called the ear canal. A short tube about 1 inch (2.5 cm) long that directs sound to the eardrum.

Auditory Nerve – Also called the vestibulocochlear nerve or acoustic nerve. Acts like a telephone line to the brain. The electrical signals generated by the hair cells are sent to the brain by this nerve.

Cochlea – The snail-shaped part of the inner ear which contains the organ of Corti also known as the organ of hearing.

dB – A measure of how loud sounds are or sound intensity (abbreviation for decibel).

Decibel – A unit of measure commonly used to describe the sounds around us (abbreviated as dB). It’s based on a logarithmic scale which means a sound that is 3 decibels higher has twice as much energy.

Eardrum – Also called the tympanic membrane. A thin membrane separates the outer ear from the inner ear. Sound waves make it vibrate; this vibration is transferred to the three bones of the middle ear.

Energy -The ability to do work, energy is just the force that causes things to move. Energy is divided into two types: potential and kinetic.

Frequency – The number of times a vibrating object oscillates (moves back and forth) in one second. Fast movements produce high-frequency sound (high pitch/tone), but slow movements mean the frequency (pitch/tone) is low.

Hertz (Hz) – A measure of frequency, abbreviated as Hz. The number of oscillations (back and forth movements) per second.

The study of sound perception is limited by the complexity of human ear mechanisms. The figure below represents the domain of perception and the thresholds of pain and listening. The pain threshold is not frequency-dependent (around 120 dB in the audible bandwidth). At the opposite side, the listening threshold, as all the equal loudness curves, is frequency-dependent. In the center are typical frequency and loudness ranges for human voice and music.
