Description

Multi-sound source relaxation sleep aiding method for stage-type sound scene guidance Technical Field The invention relates to the technical field of sound therapy relaxation and sleep aiding, in particular to a multi-sound source relaxation sleep aiding method guided by a staged sound scene. Background Along with the increase of life rhythm and psychological pressure in modern society, sleep and emotion related problems such as difficulty in falling asleep, easy awakening in shallow sleep, tension anxiety in daytime and the like are increasingly common, and the demands of technology and products for relaxing sleep assistance are continuously improved. At present, research and application of relaxation and sleep aiding at home and abroad mainly concentrate on single track playing, voice guiding meditation, rhythmic sound stimulation, instrumental sound bath, simple intelligent sleep aiding equipment and other ideas, and although the basic experience and popularization cost have certain advantages, the technology defects generally exist, and the requirements of a user on efficient, stable and comfortable relaxation and sleep aiding are difficult to meet. The key defects of the prior art are mainly that firstly, the intervention content lacks unified specifications, most of single audio playing or operator impulse combined sound effects are achieved, sound source collocation, sound intensity change, paragraph structure and time sequence organization are not explicitly standard, repeatability and contrast among different schemes are poor, effect fluctuation is remarkable, secondly, the organization of the whole process of relaxing and sleeping aid is weak, only a playing starting link is focused, how a user is guided to quickly enter a relaxed state, the relaxed state is maintained for a long time, the user stably exits from the relaxed state and completes attention resetting, systematic flow design and parameter constraint are lacked, thirdly, single sound source or simple sound track combination easily causes auditory fatigue of the user, the immersion is insufficient, attention is easily drifted, the relaxing effect is difficult to maintain for a long time, fourthly, the design of an exiting mechanism is unreasonable, the abrupt exiting of the 'playing end and stop' is easy to cause the user to remain tight, state recycling is insufficient, and resetting consistency is poor. In addition, although the existing part of intelligent sleep-aiding schemes introduce physiological parameter monitoring, physiological feedback and stage switching depth are not fused, the scheme is mainly played at a fixed time sequence and cannot adapt to individual physiological differences of different users, meanwhile, most schemes do not clearly determine the leading effect of a core sound source, and are insufficient in sound scene stability and difficult to form a continuous perception anchor point. The sound bowl is used as a sound therapy tool with long history, the stable vibration frequency emitted by the sound bowl can influence brain waves of a human body through resonance, so that the sound bowl helps to regulate emotion and reduce physiological arousal, and is suitable for being used as a core sound source for relaxing and helping sleep, but the sound bowl is not systematically integrated with staged sound scenes, physiological feedback and self-adaptive adjustment in the prior art, and the sound therapy advantages of the sound bowl cannot be fully exerted.
