This patent application discloses a method for constructing a risk prediction system for age-related hearing loss based on metabolomics, belonging to the interdisciplinary field of biomedicine and artificial intelligence. The method first acquires peripheral blood metabolomics data, pure-tone audiometry results, and age information of subjects, and then screens out age-related hearing loss patients with symmetrical hearing loss and healthy controls. Next, a hierarchical screening strategy is used to identify multiple core metabolites related to the age-related hearing loss state itself from massive amounts of data. Subsequently, based on these core metabolites, a predictive model is constructed using machine learning algorithms, and rigorously validated through independent internal and external clinical cohorts. This invention achieves early, accurate, and interpretable risk warning for age-related hearing loss, exhibiting excellent predictive performance.

This invention relates to the field of audiometry chamber technology, specifically to an audiometry chamber with an opening window, comprising an audiometry chamber body equipped with a soundproof door and an observation window; the audiometry chamber further includes: a placement cavity disposed on the side wall of the audiometry chamber body, the bottom of the placement cavity being horizontal; and a delivery unit comprising two opening window assemblies, the two opening window assemblies being respectively disposed on the inner and outer side walls of the audiometry chamber body, the two opening window assemblies being symmetrical about the placement cavity, and only one of the two opening window assemblies being able to open at any given time. This invention can promptly deliver items to test subjects experiencing physical or emotional discomfort to alleviate discomfort, and also avoids repeated testing that could aggravate discomfort.

The invention relates to a tinnitus intervention method, device and equipment based on a brain-computer interface, and relates to the technical field of tinnitus digital intervention, and the method comprises the steps: processing a pure tone audiometry result of a target user through a matching method, and obtaining input parameters such as tinnitus frequency / loudness; and performing real-time dynamic processing on the original audio in the buffer area to generate an audio block, performing band-pass filtering in combination with the tinnitus input parameters, and constructing a band-pass / band-stop filter. And introducing key noise by adopting random noise, performing optimal superposition on the noise and an audio block, analyzing signal gain, performing incisura enhancement according to a band elimination filter and the gain based on an incisura / sound channel mode, and generating incisura music. And finally, on the basis of a brain-computer interface, combining the incisura music with the neural feedback information, and carrying out comprehensive tinnitus intervention, so that the incisura music is adjusted, and a tinnitus intervention result is determined. Therefore, the brain-computer interface and the incisura music therapy are combined to realize advantage complementation, so that the tinnitus digital intervention effect is improved.

The invention relates to the technical field of auditory screening, and discloses a machine learning-based intelligent auditory screening system, which comprises an auditory measurement end and a background server, the hearing measurement end is used for detecting hearing data of a patient / user in a measurement period and storing the hearing data to the background server; the background server comprises a data module which is used for storing real-time hearing data and historical hearing state data of a patient / user. According to the intelligent hearing screening system based on machine learning, a convenient hearing test mode is provided for common users and doctors by adopting a big data technology and designing the convenient hearing test mode and hearing analysis based on big data, and rapid and accurate hearing test experience is achieved; meanwhile, according to big data analysis, the hearing loss trend is analyzed according to historical hearing test records, proper suggestions are provided for the user and doctors, and the user is helped to correctly understand the hearing condition of himself / herself.

The invention discloses a network-based mobile audiometry vehicle system and an application method. The network-based mobile audiometry vehicle system is characterized by comprising a detection fitting system, a data transmission module and a server, the detection fitting system is arranged on the audiometry vehicle and is used for hearing detection and hearing aid fitting of a user; the data transmission module is used for interacting the data of the detection fitting system, the data of the hearing aid, the user data, the fitting teacher terminal, the user terminal and the local terminal with the server; and the server is used for storing, analyzing and processing data and distributing a fitting worker. The hearing aid fitting convenience is improved, the subsequent use frequency and use experience of the hearing aid are improved, and the user experience is improved.

The present invention is a pronunciation correction system for hearing-impaired individuals. It employs an audiometry module to generate hearing impairment data for the hearing-impaired individual. A frequency enhancement module then uses this data to establish a gain model, which is applied to adjust multiple word audios, enabling the hearing-impaired individual to clearly hear the adjusted audios. An assistive learning module plays the adjusted word audios and captures the utterances repeated by the hearing-impaired individual. A speech recognition module performs speech recognition on these utterances, comparing the recognition result with the text labels corresponding to the word audios. The comparison results are sent back to the assistive learning module, which displays visual feedback to display the results. This process assists the hearing-impaired individual in correcting the pronunciation effectively.
