First, the volume of sound we hear depends on the amplitude of sound wave we receive. There are two factors, namely distance from the sound source and the path sound travels. Absorption occurs when sound travels in the air as well as hits on every object, which leads to reduction of wave amplitude same with the amount of absorption. In short, farer we are from the source, sound deteriorates more; more reflection occurs, more extent in which the volume decreases due to objects hit and distance traveled.
That is why there are more speakers behind the balcony seats than the back side than the front in theatres and halls: direct sound from the stage is much weaker where listeners stay far from the stage. Humans, especially the ones who love music much, demand great quality of music. We build theatres and music rooms of special shape to allow better enjoyment of music: we produce high-technology well-designed headphones to allow best transmittance of music to our auditory system, we develop portable music devices such as MPH and pod to allow music experience at anytime.
But why does everybody incline to music so much that we do such many things to improve our music enjoyment? Researchers have yet to find out the reason. But according to investigations and studies humans have done till now, it has been discovered that he regions in brain that are activated by music are more or less the same as those linked to other blissful stimuli such as sex, food and drugs. Blood flow in the brain bounces to swells of music in areas linked with emotion, reward and arousal. Our body and emotion can easily be initiated by music, no matter what type it is.
The relationship between body and mind has been studying and discussing over centuries. Humans have an innate to engage with music. Music influences human secretly that many of us have our emotion and feeling changed before noticing that it is due to the surrounding rhythms. When hearing strong beats, we feel like our heart is fiercely beating with them as if something invisible is hitting it; our skin is likely to bob like a float in the sea as if thousands of tiny droplets are dropping on our body; our necks and shoulders move naturally to present the beats with their movement.
When listening to melodious rhythmical flow, our index and middle fingers move like ballet dancers; our muscles are relaxed and our eyes tend to close slowly; our whole body is immersed into the comfortable and relaxing atmosphere. Humans’ sensation to music is very fine but strong. All of the reactions are so reflex and natural that we Reflection to music and human body By Kong-Sang every human being. People feel Joyful and pictures beautiful images under the influence of light-hearted pop songs; feel warmed because of soft slow classic love songs; feel excited when listening to arousing National Anthem.
Actually, our emotion changes follow two factors: the melody itself and the message it transmits. Actually, after realizing that our emotion is tightly bonded with music, we can apply music on our daily life such as emotion regulation or even disease healing. For instance, positive and happy earmarks reduce anger or cheer one up in the presence of depression. According to an experiment performed by McNally-Agony, a psychologist from the University of Montreal, people are likely to report having more positive affection after an armor has struck than they had before.
Regarding healing diseases, music functions well and has been being used in plenty of areas. As an example, music therapy helps children with attention, communication and abnormal behavior. There are often various kinds of musical instrument in a therapy room, in which the patients can find one that they are able to adapt to. The therapist either plays a guitar or piano to keep the surrounding peaceful and comfortable. It is reported that music with Joy can effectively deal with mood disorders.
Apart from mental problems, appropriate music can also help with physical diseases. One common example would be performance of rhythms in curing heart disease. Some music reduce heart rate and blood pressure in humans. For patients with coronary heart disease, this would be a great benefit. But as the impacts on different patients are not exactly the same, this healing method has not been commonly used in hospitals yet.
