Description
Technical Field
The application relates to the field of audiometric device manufacturing, in particular to a miniature audiometric device capable of carrying out one-to-many in-situ audiometry.
Background
The strong noise (including steady-state noise and pulse noise) exposure of ships often causes acute and chronic auditory system damage, and a professional platform and a technical means for noise exposure intensity real-time monitoring, personnel hearing state dynamic detection and noise reduction effect evaluation of the existing noise-proof facilities are urgently needed to be established for determining the pathogenesis of noise hearing damage and screening noise deafness susceptible people.
The detection of a hearing condition requires the use of an audiometer. The audiometer is an acoustic electronic instrument for testing the hearing function, is used in the aspects of clinic, scientific research and the like, and can provide a basis for qualitative, quantitative and positioning diagnosis of hearing loss. The method comprises the functions of pure tone audiometry, extended high-frequency audiometry, language audiometry and the like. The conventional audiometer structure is generally composed of a host (signal generator, attenuator, power amplifier, controller), a power supply, a transducer, software, a subject response device and the like. It adopts the psychoacoustics principle, through the process of electronic oscillation, amplification, attenuation, etc. the signals with different frequencies and intensities and various noise signals for masking effect in the test are transmitted to the testee by the transducer, so as to achieve the purpose of detecting the hearing sensitivity of human ears.
The traditional audiometer has large volume and complex structure, and has strict requirements on environment (acoustic environment and electromagnetic environment), field and the like during use. In recent years new techniques have emerged for in-situ audiometry using hearing aids, i.e. patients are tested in the external auditory canal with hearing aids that have been used or are to be used by themselves. Including hearing assessment tests. The hearing aid dispenser may use the hearing aid as a microphone to deliver the stimulation signal during testing. This technology is derived from in-situ testing of hearing aids (in situ), which is intended to mean testing of the physical performance of hearing aids on the actual wearer or a replacement (mannequin) that is strictly designed to have the same acoustic properties as a normal adult. Since the in-situ test is performed while worn and not in accordance with the ANSI S3.221996 standard, the test provides more accurate and effective information about the frequency gain characteristics and directivity characteristics of the hearing aid. For example, in situ testing takes into account the significant effect on the input signal sound pressure level due to diffraction effects on the wearer's body and head. However, for the dynamic detection of the hearing status of the ship crew, the hearing aid used by each patient is used in the test, so the test result has no universality. And no matter the traditional audiometer or the hearing aid is used for in-situ audiometry, the test can be carried out one by one, and the time required for one test is long, so that the method is not suitable for serving as a professional platform for dynamically detecting the hearing status of the crew on the naval vessel.
