Description

Harmonium is a sound therapy application that makes the rhythm of the moon and the sea permeate into you.

-----------
Feature
-----------
Harmonium creates healing sounds from the moon's astronomical location(moon phase and distance between the earth and the moon) and weather forecast (atmospheric pressure and tide level).

This healing sound consists of the sound of waves, the sounds of creatures, the sounds of rain and thunder, and a piano tuned to 432 Hz.

In addition, we refer to the brain science study that the relaxation of the mind and body will increase when the brain wave of a person becomes 8 to 13 Hz. Harmonium reproduces the phenomenon called Brainstem Frequency Following Response(FFR) to obtain the brain waves of this frequency.

Harmonium makes use of two types of FFR guiding sounds, 432Hz and 528Hz, according to the position of the moon and, while aligning with the tide level in real-time, changes the frequencies of the left and right sounds like the ebb and flow of the tide, guiding the brainwaves to 7.83Hz, a little lower than 8Hz.

Harmonium evokes a sense that perceive the rhythm of nature.

-----------
Function
-----------
Harmonium has three channels.

1. Concentration
Play only the ocean wave sounds.(45 min)
There are 24 ocean sound files in Harmoniums.

2. Relax
Added FFR guidance sound to the ocean wave sounds.(30 min)

3. Sleep
Ocean wave sounds,Creatures living around the ocean, Weather sounds of rain and thunder, Felt piano sound, and FFR guidance sound.(60 min)
When the moon leaves the earth, FFR guidance sound is 528 Hz, and when the moon approaches the earth, it is 432 Hz.
During the tide rise, add the target EEG frequency to the FFR guidance sound. Subtract when the tide is falling.

Ex.
At the moon moves away from the earth, the tide is rising
Left ear:528Hz + 7.83Hz = 535.83Hz
Right ear:528Hz + 0 = 528Hz
535.83Hz - 528Hz = 7.83Hz

Notes
-----------
Harmonium uses special sounds known as Frequency Following Response sound(A similar sound is binaural beats).Therefore, please do not use this app in the following cases.

Lovely

Yesterday I heard only the sound of waves and the piano, but today the wolf and the birds were singing.
I want to be able to freely mix animals and piano sounds.

Developer Response ,

Thank you for your feedback.
Your suggestion is really attractive.
We will research how to achieve that function.
