Description
Technical field
This utility model relates to a kind of audition integration instrument for training, particularly a kind of digital acoustic perception integrated training instrument that is used for the treatment of the childhood development behavior disorders such as infantile autism, hyperkinetic syndrome, aphasis.
Background technology
Audition integration training (Auditory Integration Training, referred to as AIT) created by French ENT doctor bernard (Guy.Bernard), this therapy makes full use of modern digital electronics technology equipment, utilize one group of special sound and the music Listening Training program as a kind of entirety, reach and correct the phenomenon of auditory system to acoustic processing imbalance by allowing infant listen to through the music of filtering and allocate, and stimulate brain activity, thereby reach the object of improving conduct disorder and emotional maladjustment.Since " dancing in the rain " book of mother's Anabel of U.S.'s infantile autism infant is published, the training of audition integration has obtained generally carrying out in countries in the world.In pediatric " Holy Bible " " Gunnar Nilsson pediatrics " and " practical paidonosology ", classify the training of audition integration as occupy after structural teaching and behavior therapy the 3rd selection.
The training of audition integration is a kind of special musical therapy method.Autism children great majority to music produce preference, although their world is to external world unconcerned, some or even there is no language, they mostly show great interest to music, some child even has music sense free from worldly cares and the superpower sound ability of distinguishing.When acoustical signal conducts to thalamus and cerebral cortex system by the nerve fiber of organon auditus, pitch in music, loudness of a sound, these basic elements of tone color can be directly by sub-dermal structures such as thalamuses, make brain body produce autonomic response, various sound equipments are taking the time as carrier, in the process of time, showing the audio frequency regular movements that self is orderly, and the sympathetic response that in this audio frequency regular movements and the Nature, the lived object of all tools is producing allosome isomorphism, form, open, , that closes replaces and the life regular movements increasing in order, rhythm pattern in music and tune system have marvellous common with the feature rhythm and pace of moving things of human body to a great extent.
The treatment of audition integration is also the one of sensory integration treatment.The method is by allowing experimenter listen to the music through the modulation of audition integration instrument for training, utilize instrument for training to determine whether filter certain audio frequency according to the hearing test situation of infant or reduce high frequency in music or the sound of low frequency, correct the processing imbalance of experimenter's auditory system to sound, and stimulate brain activity, thereby reach the object of improving experimenter's aphasis, disorders,communication, emotional maladjustment and conduct disorder.
In existing audition integration instrument for training, what source of sound adopted is all music, and treatment specific aim is not strong, secondly, existing audition integration instrument for training is mainly taking analogue signal as sound source signal, tonequality is not high, along with scientific and technological development, digital audio signal replaces the best means that analogue signal stores as voice data gradually, therefore need to develop a treatment with strong points, audition integration training system taking digital audio signal as source signal, again, in existing audition integration instrument for training, although the acoustical signal of some responsive frequency has been carried out to filtration treatment, but signal after treatment is not carried out to advanced treating, the tonequality fidelity of the final sound broadcasting is not high, have a strong impact on therapeutic effect, finally, in existing equipment, medical worker only can observe according to the external presentation of infant the present situation of the infant of tested person, carries out careful judgement without established data.
