Hearing evaluation detection system

Abstract

The invention relates to a hearing evaluation detection system, and the system a hearing test module, a sound field detecting module, a speech evaluation module and an upper computer. The hearing testmodule uses single-frequency sinusoidal sound for sound generation, and determines the minimum sound at various frequencies that can be heard by an ear, so as to understand the hearing loss at each frequency, and draw an audiogram, and judge the degree and nature of the deafness according to the audiogram. The speech evaluation module is used for performing the speech test of a vocabulary to understand the hearing state of a patient, and performs the discrimination and diagnosis of the hearing loss status and characteristics. The sound field detecting module is configured to determine a soundfield hearing threshold level of a bare ear and a hearing threshold level after a functional gain. The upper computer is used for controlling the hearing test module, the speech evaluation module andthe sound field detecting module, and performs the integration and preservation of the detection data result, in order to obtain a hearing evaluation test result. The economic investment of the system is low, and the accuracy of the hearing damage evaluation test result is improved, the beneficiary personnel are expanded, and the society is benefited.

Description

technical field [0001] The invention relates to the field of hearing assessment and detection, in particular to a hearing assessment and detection system. Background technique [0002] With the development of industrialization and the aggravation of environmental pollution and other factors, hearing disease has become a common disease. Clinically, hearing impairment is divided into two categories: conductive deafness and neurological deafness. Conductive deafness refers to hearing loss caused by damage to the "tympanic membrane-ossicle chain" system from the ear canal to the middle ear; nerve deafness is a sensory sensory lesion, which refers to damage to the nerve conduction pathways related to the cochlea in the inner ear or the auditory nerve to the auditory center , leading to hearing loss or disappearance, also known as sensorineural deafness. In conductive deafness, sound waves can also be transmitted from the skull to the inner ear through bone conduction to cause se...

Problems solved by technology

When carrying out hearing evaluation and detection, it is necessary to carry out hearing test, sound field detection and speech evaluation. In the prior art, the test equipment and places for hearing test, sound field detection and speech evaluation are all independent, which exists. On the one hand, due to hearing The economic investment of impairment assessment and testing is large, which reduces the number of beneficiaries, and even some hearing-impaired people, for economic reasons, only do one or two of the three tests, which affects the hearing assessment and testing results; on the other hand , the data of hearing test, sound field test and speech assessment can only be shared manually, and there are risks such as data loss and distortion of hearing loss assessment test results.
