Splashing is a movement or change in the state of movement of the body, which is repeated over time or has one or another degree of repetition.

Waves are disturbances (or changes in the state of the medium or field) that propagate through space at a finite speed.

These two concepts (splash and wave) play an important role in human life. It is through the waves that a person can understand different messages from the environment, and any messages spread in the environment have an impact on human health.

Splashes and waves have wide applications in practice. Lapping forms the basis of acoustics, optics, electrical engineering and radio engineering.

The elastic waves that produce auditory sensations in the ears of humans and animals are called sound waves.

There are too many sounds. For example: voices of people, birds, thunder, musical instruments are sounds. Sound plays an important role in human activity. Through sound, people inform each other about any unfortunate events. It should not be forgotten that the frequency that the human ear can hear is the range from 16 Hz to 20 kHz. Many sounds are inaudible to the human ear due to their low pitch, for example: low-frequency splashes of 5 to 8 Hz have the power to induce panic in people. In such a situation, a person does not hear the sound, but is ready to run away in some direction and hide himself or cover his face with his hands. In short, low-pitched sounds of 5 to 8 Hz cause a resonance event in the part of the human brain. It is through the phenomenon of resonance that people involuntarily develop a sense of fear. Today, low-pitched sounds have a positive effect on the mental activity of a person, which leads to a decrease in the mental state of people. For example: when the cars are moving on the road, although their engine emits low-speed sound waves, such sounds create a sense of fear and panic in the human being.

Primarily splashes and sound waves propagate through the air. Floating objects create waves in the air. This wave reaches the human ear and splashes its membrane.

Sound that creates pleasant emotions is called musical sound.

The sound of music includes the sound of musical instruments, tuning fork, gizhak, two strings, rubob, circle, flute, drum, trumpet, trumpet, piano, etc.

Music gives a fresh spirit and inspiration to the mental and physical condition of a person.

Ancient Greek philosophers Pythagoras, Aristotle, Plato (IV century BC) have shown that music has a positive effect on the treatment of patients.

The effect of music on the disruption of hormones in the human body is of great importance. Philosophers have noted that music can cure various diseases.

Democritus noted in one of his works that the influence of musical instruments has a great influence on humanity. He suggested that listening to a musical instrument of the flute has an effect on the treatment of a deadly infectious disease. In 1913 in Russia at the initiative of V.M. Bekhterev research committee of music therapy was established. This committee includes a number of well-known Russian doctors and representatives of the world of art: S.S. Korsakova, V.M. Bekhterev, I.M. Dogelya, I.M. Sechenov, I.R. Tarkhanova and others.

Doctors at the Munich University Hospital used music therapy to treat children with paralysis. In recent years, doctors have been recommending listening to the works of composers Beethoven and Mozart for the treatment of patients, as well as for the treatment of stomach worms.

The effect of musical instruments on the human body is enormous. For example: 19-23 hours of listening to the sound of the drum instrument has a good effect on the spine, the guitar on the heart, the flute on the liver, the clarinet on the gall bladder, the harmonica on the colon, the harp on the lungs, the saxophone on the kidneys, the piano on the stomach, the trumpet on the stomach. , intestinal irritation, etc.

In conclusion, continuous listening to music gives a fresh inspiration to all parts of the body and leads to longevity of mankind.
