Abstract
The invention discloses a fractional frequency regulating method of a hearing correction device, which includes the following steps of: S1, collecting hearing loss data of multiple sound frequencies of a subject in a hearing threshold range; S2, analyzing and processing the hearing loss data, and generating a hearing loss curve; and S3, respectively compensating various frequencies of correction sound according to the hearing loss curve, and outputting the correction sound. The fractional frequency regulating method outputs the correction sound after the hearing loss of the subject at multiple sound frequencies is collected and the hearing loss curve is generated. The hearing compensation is performed on a hearing loss region of the subject without influencing a normal hearing region, a stimulation demand of hearing loss region is satisfied, and an unimpaired hearing region is protected.
Description
Technical field
The present invention relates to a kind of frequency division regulate and control method of hearing apparatus for correcting.
Background technology
Existing music or Audio Players, as tinnitus sound therapentic equipment, the sound of output is joinedSide only can regulate the loudness of sound on the whole, and tinnitus patient merges hearing loss conventionallySymptom, i.e. the deafness difference of each frequency in the threshold of audibility, the loudness of sound entirety regulatesAlso the normal good hearing position that has stimulated patient in stimulating patient's hearing loss position, althoughThe tinnitus of tinnitus patient is produced to inhibitory action, but also can cause patient's normal good hearing positionOverstimulation and damage.
Summary of the invention
The object of this invention is to provide a kind of frequency division regulate and control method of hearing apparatus for correcting, at least canEnough one of address the above problem.
For achieving the above object, according to an aspect of the present invention, provide a kind of hearing to correctThe frequency division regulate and control method of device, comprises the following steps:
The hearing loss data of S1, collection person under inspection multiple sound frequencies within the scope of the threshold of audibility;
S2, by the processing of hearing loss data analysis, generate hearing loss curve;
S3, compensate respectively in each frequency of rectification sound according to hearing loss curve, output is rectifiedPositive sound.
Beneficial effect of the present invention is: well-behaved frequency modulation control method is gathering person under inspection's hearing multipleThe hearing loss of sound frequency generates after hearing loss curve, just carries out the output of rectification sound, energyEnough carry out hearing compensation for person under inspection's hearing loss region, and do not affect normal hearing districtTerritory, meets the stimulation in hearing impairment region is required, protects and do not damage hearing region.
In some embodiments, in step S1, while gathering person under inspection's hearing loss data,The different frequency pure tone of output within the scope of the threshold of audibility, draws the hearing of person under inspection in each detection frequencyThe extent of damage. Thus, adopt pure tone test can obtain hearing loss data more accurately.
In some embodiments, in step S3, at the offset of each frequency of rectification soundFor the loudness difference of hearing loss curve and normal good hearing. Thus, at corresponding sound frequencyCompensate corresponding loudness difference, can effectively improve person under inspection's listening comfort, to reach betterResult for the treatment of.
In some embodiments, in step S2, by hearing loss data analysis placeWhen reason, the hearing loss data of each frequency are in turn connected to form to level and smooth curve. Thereby mostMeasure and on few testing time, obtain the hearing loss of person under inspection on cline frequency.
In some embodiments, in step S1, the different frequency pure tone phase successively of outputInterval 20～200Hz. Thereby can obtain more data, to generate hearing loss song accuratelyLine.
Detailed description of the invention
The present invention is further detailed explanation below.
The frequency division regulate and control method of hearing apparatus for correcting of the present invention, comprises the following steps:
The hearing loss data of S1, collection person under inspection multiple sound frequencies within the scope of the threshold of audibility.
While gathering person under inspection's hearing loss data, the different frequency of output within the scope of the threshold of audibility is pureSound, draws the deafness of person under inspection in each detection frequency. The different frequency pure tone of output20～200Hz separately successively. The threshold of audibility scope that the present invention measures is 20～10000Hz, adoptsCollection person under inspection is in the hearing loss of 20～10000Hz.
At 20～100Hz, test acoustic frequency is spaced apart 20Hz, at 1000～3000Hz, and testAcoustic frequency is spaced apart 50Hz, and at 3000～5000Hz, test acoustic frequency is spaced apart 100Hz,At 5000～10000Hz, test acoustic frequency is spaced apart 200Hz. When person under inspection is in a certain frequencyWhen deafness is serious in scope, also need in this frequency range, carry out detailed numberAccording to collection, to gather hearing loss data every 20Hz, to obtain reliable hearing lossCurve.
Hearing apparatus for correcting is also provided with data acquisition unit, for receiving and store person under inspection'sHearing loss data. Hearing apparatus for correcting is provided with man-machine interaction unit, for to data acquisitionUnit sends hearing loss data, for showing the frequency of detection sound and loudness, for regulating inspectionThe loudness of survey sound. Hearing apparatus for correcting is also provided with detection sound output unit, for exporting differenceThe pure tone of frequency.
Pure tone refers to the sine wave with single-frequency. Hearing loss is that people's ear is in a certain frequencyThe decibels that the threshold of audibility exceeds than normal threshold of audibility.
When hearing loss data acquisition, make the detection sound output unit of hearing apparatus for correcting a certainThe loudness of frequency increases gradually, and loudness when person under inspection hears the sound of this frequency and normal person shouldWhen the loudness of hearing is made comparisons, obtain hearing loss data.
S2, by the processing of hearing loss data analysis, generate hearing loss curve.
The data processing unit of hearing apparatus for correcting, will to the processing of hearing loss data analysisThe hearing loss data of each frequency are in turn connected to form level and smooth curve, to obtain person under inspection wholeDeafness on cline frequency in individual test specification.
S3, compensate respectively in each frequency of rectification sound according to hearing loss curve, output is rectifiedPositive sound.
Offset in each frequency of rectification sound is the loudness of hearing loss curve and normal good hearingDifference. Thereby can compensate corresponding loudness difference at corresponding sound frequency, can effectively improve and be subject toInspection person's listening comfort, to reach good result for the treatment of.
The sound generation unit of hearing apparatus for correcting receives the data of data processing unit, according toHearing loss in each frequency, generates gain signal, makes each frequency sound of output in loudnessUpper increase. Thereby can increase person under inspection's comfort level. Therefore, well-behaved frequency modulation control method canHearing compensation is carried out in hearing loss region for person under inspection, and does not affect normal hearing districtTerritory, meets the stimulation in hearing impairment region is required, protects and do not damage hearing region.
Above-described is only some embodiments of the present invention. For the ordinary skill of this areaPersonnel, without departing from the concept of the premise of the invention, can also make some distortionAnd improvement, these all belong to protection scope of the present invention.
