Audio selection needs to match the age and development of the listener

Wonderful sounds, the assembly of the world's wisdom, depicting the world's wind and snow, gathering and relaxing, releasing and talking. If you encounter a device that truly expresses the original sound, it is enjoyable.

Killer sound quality, bring double damage to mind and body

Wonderful sounds, the assembly of the world's wisdom, depicting the world's wind and snow, gathering and relaxing, releasing and talking. If you encounter a device that truly expresses the original sound, it is enjoyable. On the contrary, it is not only a torture but also a physical injury. According to neurologists, the noisy sound quality in inferior audio is easy to make people feel emotional and even temperament. In severe cases, it can lead to hearing loss and even mental disorders. The sound reproduces the music by technology. In this process, because of the difference between the advantages and disadvantages of the equipment, the playing sound is inconsistent with the original sound. Some "killer sound quality" with noise, harsh treble and even the original sound is played, and the human ear is sharp. The sound adaptability is very weak. The most direct hazard to the human body is the hearing damage, especially the sharp noise that suddenly bursts out, which can cause acute trauma to the auditory organs, causing rupture of the tympanic membrane, getting lost bleeding, and the spiral from the basement membrane. Acute exfoliation may cause the ear to completely lose hearing, ie, shock deafness. According to the survey, most of the audio products on the market today that are sold at the low-end and mid-end prices are sold to the elderly and children, and it is these low-cost products that cause harm to these most vulnerable groups that cannot protect themselves.

Be wary, the volume of the error is not good.

Some new fathers and new mothers are cultivating their children's music cells. They often use music, TV, and audio to listen to children. I don't know if they don't help the children but harm the children. There is such an example. A father puts songs on the children every day and hopes to cultivate musical genius. But when the child grows to 4 years old, he is still unclear. When the doctor tells the child that the music he has hurt hurts the child, he regrets that it is a pity. Unrecoverable. Scientific experiments have shown that sounds of 50 to 90 decibels can cause changes in neonatal respiration. The strong, high-pitched, and long-pitched sounds that the baby emits on the device appear earlier and more sensitively than the response to the human voice. Once the baby reacts strongly to the instrument sound, the response to the human voice is diminished. In this way, if you lose the opportunity to communicate with adults, the phenomenon of smiling and sprinkling children will be less. In the future, there may be problems with "speaking late", "unclear speech", or "strange". Scientists have found that children who have different degrees of obstacles after birth, if they are affected by the sound of the device, will make the development of the brain more severely contused, thus making the brain more backward.

Choose to match the sound of the brain so that your family is no longer injured

Keeping your family away from harm, in addition to considering whether the music matches the listener's mind, you also need to consider whether the volume is high, the tone is perfect, and the sound quality is not cleared. But not everyone has the professional level of tuning sound, knowing what kind of pitch and volume is most suitable for the listener, and the super-audio unique audio playback self-test device, online audio device adjustment, control, always keep the original sound The playing status allows each owner to enjoy the live performance of the master at all times.

1. Real-time online calibration The cloud data receiving center of 慑力音响 generates control signals to send signals through the network control center, which can adjust the sound for the user online, and keep the original sound quality at any time.

2. The audio playback environment predicts when the data receiving center receives the real-time parameters of the audio power amplifier, and compares the pre-stored data to determine whether the audio player's own parameters are suitable for continuously playing music. If the environment predicts that its own parameters are beyond the pre-stored range, the system will send a signal through the network control center to turn off the audio amplifier and provide maintenance information to the user.

3. Remote automatic audio compensation For different music types, adjust the high-pitched or mid-range crossover circuit of the frequency equalization distribution circuit in the speaker online, so as to compensate for the lack of high-pitched or low-frequency audio components, and finally achieve suppression of acoustic feedback and improve sound quality. , to modify, beautify the sound, improve the sound quality.

4.α music brain wave detection If the music played does not contain the 8-13 Hz alpha brain wave frequency, the audio playback device is allowed to enter the normal playing music stage; if the played music contains the 8-13 Hz alpha brain wave frequency, then Turn on the special infrasound sounding device, and adjust the high-frequency crossover circuit of the frequency equalization distribution circuit in the speaker to achieve the best puzzle effect of α brain wave, and allow the audio playback device to enter the normal playing music stage.

Composite Suspension Insulator is also referred to as "composite long rod insulators." Suspension Type Insulator has a better mechanical performance and electric performance than porcelain insulators, and the tolerance of safe operation is big, Suspension Insulator is the renew products for electric power line. Electric Composite Suspension Insulator as a substitute for cap-pin insulators and also for critical environmental conditions such as high contamination.
