Description

Technical Field

[0001] The invention relates to an auditory space positioning detection and training instrument, and belongs to the technical field of auditory testing. Background Art

[0002] Auditory spatial localization is the judgment of the spatial position of the sound source. Sound source localization is an important component of auditory function and is the key to speech comprehension in a noisy environment. Any type of hearing damage will affect sound source localization. Patients with hearing loss often complain that they cannot accurately locate the target sound source and hear verbal communication in daily environments, especially in dense traffic environments. They cannot quickly and accurately identify oncoming vehicles, which brings great inconvenience to daily life, affects social interaction and increases the risk of accidents. In addition, the ability to localize sound sources plays an important guiding role in auditory implants and auditory assistance strategies. Through training, the patient's auditory spatial localization ability and multi-system sensory integration after auditory compensation can be improved. Furthermore, electroencephalographic physiological research related to sound source localization is also one of the current research hotspots. It is of great significance to accurately assess the sound source localization ability of hearing-impaired patients.

[0003] However, the speakers of existing testing equipment are not completely circular in the horizontal direction, nor are they 360-degree fully circular surround sound sources, making it impossible to perform all-round auditory spatial positioning testing and subsequent training. At the same time, in order to ensure the accuracy of the test data, it is necessary to change the angle between two adjacent speakers and the distance between the speaker and the tester, and to use multiple sets of data to ensure the accuracy of the final test. Existing testing equipment cannot perform this type of operation well. Summary of the invention

[0011] Preferably, the widths of some of the sliding blocks are greater than the thickness of the corresponding mounting plates, the openings of some of the sliding grooves are matched with the corresponding mounting plates, and the interiors of some of the sliding grooves are matched with the sliding blocks.

[0012] Auditory spatial localization detection includes the following steps:

[0013] Step 1: Multiple speakers are placed in an arc shape at a certain interval angle (usually 15° or 30°) on a plane with the patient as the center. The radius ranges from 0.85-2.35 meters. The tester stands in the center. The sound is randomly emitted by one of the speakers. The signal sound can be a pure tone, noise, word or sentence. The content of the behavioral test of sound source localization ability mainly includes discrimination test (angle discrimination threshold) and recognition test (angle deviation);

The two sounds are emitted successively by two speakers at a certain angle, and the test subject is asked to distinguish whether they are emitted by two different speakers. Then the angle between the sounding speakers is gradually reduced until the patient cannot distinguish, thus achieving the test of the angle discrimination threshold:

[0015] Step 3: Make one of the sound sources emit a sound. After hearing a sound, the subject uses the long rod in his hand to point out the location of the sound source he thinks, and see how much the angle difference is with the real sound source, so as to achieve the angle deviation test;

Through training, the patient's auditory spatial positioning ability and multi-system sensory integration after auditory compensation can be improved.

[0030] Auditory spatial localization detection includes the following steps:

[0031] Step 1: Multiple speakers are placed in an arc shape at a certain interval angle (usually 15° or 30°) on a plane with the patient as the center. The radius ranges from 0.85-2.35 meters. The tester stands in the center. The sound is randomly emitted by one of the speakers. The signal sound can be a pure tone, noise, word or sentence. The content of the behavioral test of sound source localization ability mainly includes discrimination test (angle discrimination threshold) and recognition test (angle deviation);

[0032] Step 2: When two sound sources emit sound continuously in the horizontal direction, the test subject can just distinguish the minimum angle between the two sound sources. The two sounds are emitted successively by two speakers at a certain angle, and the test subject is asked to distinguish whether they are emitted by two different speakers. Then the angle between the sounding speakers is gradually reduced until the patient cannot distinguish, thus achieving the test of the angle discrimination threshold:

[0033] Step 3: Make one of the sound sources emit a sound. After hearing a sound, the subject uses the long rod in his hand to point out the location of the sound source he thinks, and see how much the angle difference is with the real sound source, so as to achieve the angle deviation test;

[0034] Step 4: Through sound source localization detection combined with brain electrophysiological research, further explore the pathophysiological mechanism (especially central cortical remodeling) of hearing loss, auditory intervention, tinnitus, and decreased vestibular function.

[0035] Specifically, when the present invention is used, the tester sits cross-legged at the center of the fixed plate 2, and makes two speakers 9 at a certain angle to each other make sounds. The tester then distinguishes whether the sounds are made by two different speakers 9, and then gradually narrows the angle between the sound-making speakers 9 until the patient cannot distinguish, thereby completing the test of the angle discrimination threshold. When performing the angle deviation test, one speaker 9 makes a sound. After receiving the sound, the tester moves the identification block 52 to point the identification block 52 to the position of the sound source that he thinks. The angle of the corresponding speaker 9 can be accurately known through the positioning block 11. Therefore, the actual error can be clearly known based on the angle difference between the positioning block 11 and the identification block 52. In order to ensure the accuracy of the final test data, the mounting plate 10 is pushed, and the mounting plate 10 can rotate along the second annular groove 8 through the support 13 and the ball 14, so that the distance between two adjacent speakers 9 can be adjusted. At the same time, the control block 62 is rotated, and the control block 62 drives the screw 61 to rotate, and the mounting block 63 threadedly connected to the screw 61 drives the speaker 9 to move, and the distance between the speaker 9 and the tester is adjusted. When the speaker 9 moves, it drives the connecting block 73 to move. The distance between the speaker 9 and the tester can be known according to the scale line 71 on the support rod 72, which is convenient for operation and collects multiple groups of test data, thereby ensuring the accuracy of the final test result.
