Description
The present invention relates to the improvement of sense of hearing study, also relating to the equipment for improving sense of hearing delay and method.
Study hearing, hearing problem and individual auditory to stimulate for a long time.The theoretical premise stimulated for individual auditory is based on the research carried out the 1950's, and it is relevant with the hypersensitivity of hearing.The imbalance having observed hearing affects the commitment of speech development and study reading, and causes mental illness problem.
Such as, French doctor AlfredTomatis has developed a kind of method, is wherein leached from sonic stimulation by low-frequency sound, and uses the sound of process like this as the Training Practicing in hearing.Be diagnosed as by many people of difficulty of learning to have auditory processing imbalance and difficulty in hearing particularly in low frequency range.
The auditory sense cognition imbalance particularly caused due to temporal structure and the quick transience of auditory cues is usually also relevant with Dyslexia.Under observation, auditory processing imbalance is the growth of the delay of language and speech at children's Early manifestation, but problematic feature is remained to adulthood by many people, causes difficulty of learning.
An example of auditory processing imbalance is that the sense of hearing postpones, caused by its sound heard by ears in the brain unsuccessful synchronous.When sound is asynchronous, the sound arrived via an ear is delayed by, and affects in fact the language learning technical ability of people like this.
Be known in the art that such as solving the apparatus and method of stutter problem.Open US3101081 describes a kind of device for solving stutter problem.Reduce the interference of laterality aspect according to the device intends of open US3101081, enter the volume of the sound in one of them ear by means of this device adjustable.
In open US2010172506, also describe hearing aid device, the object of this device to alleviate the auditory disorders in one of them ear.Device described by US2010172506 works by means of the loudspeaker be arranged in two ears (1R, 1L).This device works like this and the signal of telecommunication produced by the loudspeaker in ears is combined, and repeats output sound in the side with good hearing thus.First the signal combination will produced by left side and side right loudspeaker, and signal SL (t) postponing after this to be produced by side left loudspeaker is so that by two signal combination.
According to open US201131331 also known a kind of technical scheme describing laterality process, by means of this technical scheme, manufacture a kind of system identifying also location sound signal, even if the height of the instantaneous reception of sound and sound may be different between left ear and auris dextra.This system is arranged to only to replace the time difference between ITD(ear that nature exists) and ILD (interaural intensity difference) calculating, it is caused by the alternate position spike towards the left ear on the head of sound source and auris dextra.
By means of disclosed technical scheme in the prior art, the audio signal of ear can not will be arrived according to the needs of user personalized.The possible frequency response all reckoning without ear in prior art is open is poor.
