Long-term listening to alpha waves is harmful.

Many people have the habit of listening to music before going to bed. This habit is not because the vibration of alpha brain waves causes the brain to produce alpha brain waves to help sleep, but because the music produces a kind of "white noise" , covering up household appliances, floors and other noise. At the same time, listening to your favorite music is also a psychological suggestion, which indicates quietness and safety.

Since it is said that listening to music can help us calm down physically and psychologically, why is it said that long-term "listening" to alpha infrasonic music produced by others "may" be harmful.

Although we cannot hear infrasound waves, our body organs can sense them. The frequency of infrasound waves is very low, and the absorption coefficient of the atmosphere for infrasound waves is small, causing infrasound waves of the same energy to travel farther than high-frequency sound waves.

The frequency of infrasound waves is close to the natural frequencies of human organs (the natural frequencies of human organs are 3 to 17 Hz, the natural frequencies of the head are 8 to 12 Hz, and the natural frequencies of abdominal viscera are 4 to 6 Hz). When infrasound waves act on the human body, human organs are prone to vibrations, causing human body dysfunction or damage, increased blood pressure, and general discomfort; the balance function of the mind will also be destroyed, resulting in a sense of spinning, nausea, and discomfort. .

Many people living in high-rise buildings will feel dizzy and nauseated during storms. This is due to infrasound waves. Of course, the so-called infrasound murder story requires extremely high energy and high requirements on equipment, angles, distances, environments, etc. Infrasound waves do not need to rise to the level of fear.
