Abstract

The invention relates to a device of a spatial auditory clinical audiometric system. The audiometric system and the device are suitable for a small-scale acoustic space used clinically in a hospital,and can support behavioral tests of spatial direction and distance auditory localization under various conditions comprising a quiet environment or a noise environment, a single sound source or a plurality of sound sources, coincide or separation of a noise source and a target sound source, and the like. By changing the interval of loudspeakers on a semi-circular ring, space auditory capability audiometry with different spatial resolutions is realized; change of the azimuth angle of a test seat is controlled through rotation of a numerical control turntable so as to meet audiometry requirements of different sound source spatial orientations; and the numerical control turntable for fixing the test seat is placed on a ground track so as to realize a spatial auditory distance localization capability test. The device can adapt to the spatial auditory clinical audiometry under a condition of small acoustic space, provides an effective test scheme of whole-space spatial auditory capability on a horizontal plane in a limited space, and can well meet requirements of spatial coordinate precision of otological clinical spatial auditory tests.

Description

technical field [0001] The invention relates to the fields of electroacoustics and medical equipment, in particular to a device for a spatial hearing clinical audiometry system. The audiometry system and device are suitable for small-scale acoustic spaces used clinically in hospitals, and can support behavioral tests of spatial direction and distance auditory positioning under various conditions. Background technique [0002] Hearing examination or audiometry is an examination to understand the state of auditory function and diagnose diseases of the auditory system by observing the subjects' responses to sound stimuli. The purpose of the hearing examination is to clarify whether there is hearing impairment, the degree of hearing loss, and the nature and location of hearing loss. The purpose of the sound source localization examination is mainly to detect the subject's angular perception of the position of the sound source. It can be used to study the sound source localizat...
