Sound is basically the
continuous and regular vibrations that travels through air or another medium
that can be heard. Human being can listen sounds from 20Hz to 20,000Hz. Sound is
capable of producing powerful reactions in the listener - whether it's a snake's
warning hiss, or the youth song playing on radio. Every moment of our life, we
are listening something. Scholars have been fascinated by the relationship
between sound and emotional states since at least the time of the Ancient Greeks
and modern neuroscience has led to some fascinating advances in our
understanding of why our ears and emotions have such a strong bond.
Sound affects directly on our behavior, our attitude and our communications etc.
A 2009 report from Sweden’s Lund University put forward six psychological
mechanisms through which emotions may be produced when the brain reacts to
sound. 1) Brain System Reflex, 2) Evaluating Conditioning, 3) Emotional
Contagion, 4) Visual Imagery, 5) Episodic Memory, 6) Music Expectancy. Human
emotions produced by this mechanism. Some sounds relaxes peoples, some make them
extremist. Some make them love some make them hatred. Some make the happy some
makes sad. Some makes them motivated and some makes demotivated.
Your brain is made up of billions of brain cells called neurons, and your
neurons (just like the rest of your body) use electricity to communicate with
each other. Human brainwave pattern are generally categorized in 4 parts. Alpha,
Beta, Theta & Delta. All of the best state of listening is Alpha because in this
state human can feels Relax, Improved, Healthy, Competent etc. This state is
also called “The Zone”. Nice and Sweet sounds make peoples happy and energetic.
An old quote is that ‘Music is the Nutrition of the Soul’. This is true,
According to the world wide survey music plays and important role for betterment
of human life. Best frequency for listen the music is 5000Hz.
There are also some bad effects of heavy or bad sounds or we can say ‘Noise’ on
human body. Due to heavy noise or sound there is the big chance of Hearing Loss,
Stress, Headache, Stomach Ulcers, Vertigo, Fatigue, Annoyance etc. Due to this
sleep disturbance, fatness and other problems also occurs. Due to high noise
Human Hormones also effected, Men and Women’s fertilizers can be weakens. If the
music level increase to the certain limit, women can lost their ability to get
pregnant. So, human being listens something in every moment. There are some
influence of sound on human nature and body too. Sounds effect peoples
everywhere, every time.
