Description
Technical Field
The invention relates to the technical field of cognition and electroacoustic, in particular to a portable biological emotion regulating device and method utilizing audible sound waves.
Background
In human daily production and life, sound waves exist everywhere and often affect the mood of people. For example, soothing music can relax and calm people; an irritating warning sound or a sharp glass scraping sound often causes people to be alert and irritated. Existing studies have shown that white noise (white noise) or pink noise (pink noise), which covers the human's true auditory range (20-20000Hz) and is stimulated by monotonous sounds of the same energy density at various frequencies, as auditory stimuli, increases the brain electrical delta rhythm, calms the human and produces drowsiness. In addition, studies have found that when different rhythms of monosyllabic audio are played for SD rats, the behaviors, body weight, sugar water preference rate, hippocampus 5-HT and DA concentration, and hippocampus dopamine D2 receptor of the SD rats all change differently according to different rhythms. It can be seen that the corresponding audible sound waves all have a certain effect on the mood of the human animal. In addition, infrasound and ultrasonic sound waves at certain frequencies also affect the mood of people and animals, and for example, studies show that infrasound with low intensity frequency of about 7Hz can cause dysphoria when acting on human ears, and can show symptoms such as nonspecific stress response and neuroendocrine disturbance.
Amplitude modulation is a signal modulation method, which is a method that makes the amplitude of carrier wave change according to the change rule of the required transmission signal, but the frequency remains unchanged, and is widely applied to signal transmission. The amplitude modulation process is to directly control the amplitude of the high-frequency oscillation with the low-frequency signal so that the high-frequency signal has the characteristics of the low-frequency signal, and therefore the low-frequency signal is called a modulation signal or a modulation wave, the high-frequency oscillation is called a carrier wave, and the modulated high-frequency oscillation is called a modulated wave. Amplitude modulation systems are inexpensive and easy to generate and recover. Thus, the sound waves in the originally inaudible frequency range, infrasonic or ultrasonic, can be applied to the high-frequency signal in an amplitude-modulated manner and converted into audible sound waves.
In the prior art, the transcranial electrical stimulation method is widely adopted nowadays for the emotion regulation of people. Transcranial electrical stimulation is a non-invasive neurostimulation technique, which uses electrodes to apply specific low-intensity current to specific brain regions, so as to achieve the purpose of regulating the activity of cerebral cortex nerves. The technology is already applied to the treatment of clinical mental diseases, and is also applied to the regulation of human emotions and behavior. However, the transcranial electrical stimulation method has certain limitations, and is a contact-type regulation method, in which the electrodes need to be attached to the scalp of a human or an animal to function, and the human or the animal needs to be in a relatively calm state. However, if the emotion of the human or the animal is regulated and controlled by using the sound waves, the contact can be avoided, the activity state of the human or the animal is not required, and the method is a more convenient and widely feasible emotion regulation and control mode.
The patent document with the publication number of CN108873940A discloses mood interactive system based on sound wave detection, including unmanned aerial vehicle, unmanned aerial vehicle includes unmanned aerial vehicle flight system to and the big dipper module and the flight circuit database of being connected with unmanned aerial vehicle flight system, and with unmanned aerial vehicle flight system connection processor unit, the power supply interface of processor unit is connected with battery module, and the digital signal output part of processor unit is connected with voice broadcast module and video display module, and the digital signal input part of processor unit is connected with the sound wave detection module, and the serial bus of processor unit has storage module. This mood interactive system based on sound wave detection makes a sound after the resident family returns home, and sound wave detection module obtains the sound that the resident family sent fast, later opens unmanned aerial vehicle flight system through the processor unit, controls unmanned aerial vehicle flight to residence gate position and meets the resident family, shows the expression and plays greeting pronunciation through voice module through the display module.
Therefore, a new technical solution needs to be proposed.
