Problems solved by technology

During the matching process, the fitter refers to the patient's audiogram, imports the audiogram data into the fitting system, and then adjusts the input sound gain, and the patient himself informs the fitter whether the volume of the sound is appropriate through subjective reactions. This subjective description is often inaccurate and will affect the actual listening effect
[0003] Measurements are currently made by simulating the sound output in standard couplers and ear simulators, however, standard couplers and ear simulators are very different from our real ears, because each hearing-impaired patient's hearing is different (Even the hearing of the left and right ears of the same patient is different, that is, the sensitivity of the left and right ears of tinnitus patients to different frequency sounds and the sound pressure levels that cause perceptual responses are different), so such test results are not very accurate. objective

Embodiment 1

[0035] Figure 1~2 A device for objectively simulating and regulating the hearing state of the real ear according to an embodiment of the present invention is schematically shown.

[0036] Such as Figure 1~2 As shown, the device for objectively simulating and regulating the hearing state of the real ear includes a sound playback system 2 , an external auditory canal body bracket 3 , a DSP processing system 4 and a computer 1 . The sound playing system 2 is connected with the DSP processing system 4 , and the computer 1 is connected with the DSP processing system 4 .

[0037] The external auditory canal body support 3 is used to imitate the patient's ear canal model. The external auditory canal body support 3 of this embodiment is used to embed the ear mold of the patient's ear canal shape, and then make a model that imitates the shape of the individual's ear canal. The external auditory canal body bracket 3 is made of a material with high plasticity, reusability, and close...

Embodiment 2

[0062] image 3 A device for objectively simulating and regulating the hearing state of the real ear according to another embodiment of the present invention is schematically shown.

[0063] Such as image 3 As shown, the structure of this device is basically the same as that of the device for objectively simulating and regulating the hearing state of the real ear in Embodiment 1, the difference being that the sound playback system 2 in this embodiment does not include the earphone holder 21 .

[0064] The sound playing device 22 of this embodiment is directly installed in the external auditory canal body support 3 and forms an integral body with the external auditory canal body support 3 . When in use, directly insert the sound player 22 such as earphone or loudspeaker into the external auditory canal body support 3, so that the external auditory canal body support 3 and the housing 41 of the DSP processing system 4 are connected as a whole, and the sound of the in-ear earph...

Abstract

The invention discloses a device for objectively simulating and controlling hearing state of true ears. The device comprises a sound playing system, an external auditory canal support, a DSP processing system and a computer, wherein the sound playing system is connected with the DSP processing system, the computer is connected with the DSP processing system, the external auditory canal support is used for coping a patient auditory canal model, the sound playing system comprises a sound player mounted on the external auditory canal support, the DSP processing system comprises a microphone and a DSP chip which are connected, and the sound player, the computer and the DSP chip are connected. Thus, a complete artificial ear fitting system is established, integrates data acquisition, receiving, measurement, feedback regulation and coding matching, and can help hearing loss or tinninus patients to rapidly and safely select proper sound waveforms, acquire more precise sound stimulation and auditory perception under smaller sound pressure level and realize better and more significant rehabilitation effects while protecting hearing functions.

Description

technical field [0001] The invention relates to the field of audiology equipment, in particular to a device and method for objectively simulating and regulating the hearing state of the real ear. Background technique [0002] For patients with hearing impairment or tinnitus, it is usually necessary to choose hearing aids or tinnitus sound therapy devices. These devices input sound signals to the human ear to achieve rehabilitation and other purposes. During the matching process, the fitter refers to the patient's audiogram, imports the audiogram data into the fitting system, and then adjusts the input sound gain, and the patient himself informs the fitter whether the volume of the sound is appropriate through subjective reactions. This subjective description is often inaccurate and will affect the actual listening effect. [0003] Measurements are currently made by simulating the sound output in standard couplers and ear simulators, however, standard couplers and ear simula...
