Auditory space positioning detecting and training instrument

Abstract

The invention discloses an auditory space positioning detecting and training instrument. The auditory space positioning detecting and training instrument comprises a chassis; a fixing disc is fixedly connected to the center position of the upper end of the chassis; a first annular groove is formed in the upper end of the fixing disc; an identification mechanism is arranged in the first annular groove; angle lines are arranged on the edge of the fixing disc; a plurality of mounting plates are evenly arranged on the outer side of the fixing disc; positioning blocks are fixedly connected to the upper ends of the plurality of mounting plates correspondingly; the multiple positioning blocks correspond to the angle lines; a loudspeaker is arranged on one side of each of the multiple positioning block; the multiple loudspeakers and the corresponding mounting plates are connected through adjusting mechanisms; an indicating mechanism is arranged on one side of the corresponding adjusting mechanism; supporting columns are vertically fixed to the bottom ends of the multiple mounting plates; sliding blocks are fixedly connected to the ends, close to the fixing disc, of the multiple mounting plates; and the outer side wall of the fixing disc is provided with a sliding groove. According to the auditory space positioning detecting and training instrument, detection is more accurate through 360-degree auditory space positioning detecting and training instrument, and auditory positioning ability comparison tests of normal people and different types of hearing impairment people can be carried out.

Description

technical field [0001] The invention relates to an auditory space positioning detection and training instrument, belonging to the technical field of auditory testing. Background technique [0002] Auditory spatial localization is the judgment of the spatial location of sound sources. Sound source localization is an important component of auditory function and the key to speech understanding in noisy environments. Any type of hearing impairment can affect sound source localization. Patients with hearing loss often complain that they cannot accurately locate the target sound source and hear speech clearly in the daily environment, especially in a dense traffic environment, and cannot quickly and accurately identify passing vehicles, which brings great inconvenience to daily life, affects social interaction and increases risk of accidents. In addition, the sound source localization ability plays an important guiding role in auditory implantation and auditory assistance strat...

Problems solved by technology

[0003] However, the speaker composition of the existing detection equipment is not a complete ring in the horizontal direction, and it is not a 360-degree full ring surround sound source, so it is impossible to perform all-round auditory space positioning detection and follow-up training. At the same time, in order to ensure the accuracy of the detection data, it is necessary to The angle between the two speakers and the distance between the speaker and the tester are changed, and multiple sets of data are used to ensure the accuracy of the final test. Existing test equipment cannot perform this type of operation well.
