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...
