This utility model discloses a low-noise centrifugal pump for petrochemical applications, comprising a centrifugal pump body, an impeller movably mounted inside the pump body with an impeller shaft mounted on it, an inlet pipe at the front of the pump body, a drain pipe at the top of the pump body, and a low-noise mechanism wrapped around the outside of the pump body. The low-noise mechanism consists of noise reduction covers A, B, C, and D. Noise reduction cover B is fixedly mounted at one end of noise reduction cover A, and noise reduction cover D is fixedly mounted at one end of noise reduction cover C. This low-noise centrifugal pump for petrochemical applications features modularly designed noise reduction covers that can be quickly installed using a mounting bracket without complex tools or specialized skills, reducing the noise level generated by the centrifugal pump and preventing damage to the inner ear hair cells of factory workers, thus avoiding irreversible hearing loss. The rock wool itself has a porous fiber structure, primarily absorbing mid-to-high frequency noise.

Compensation for the hearing loss of a user may be provided in an audio device, based on the hearing information of a user input to the audio device, by applying one or more different forms of hearing loss compensation to an audio signal output via the audio device, while also enabling a user to control the degree to which the one or more different forms of hearing loss compensation are applied to the audio signal output via the audio device. A user may be presented with a selection of such hearing compensation controls based on which of a plurality of common hearing profiles the user's hearing information most closely matches.

The application discloses a hearing loss GRM7 gene susceptibility identification method and system, relates to the technical field of magnetic resonance medical image processing and bioinformatics, and comprises the following steps: acquiring multi-modal data of a to-be-detected individual, performing feature extraction and calculation on the multi-modal data, obtaining multi-dimensional quantitative indexes, splicing the multi-dimensional quantitative indexes into a four-dimensional feature vector according to a preset order, performing Z-score standardization on the four-dimensional feature vector, performing prediction on the standardized four-dimensional feature vector through a pre-trained binary classification support vector machine model, and obtaining a probability value of the to-be-detected individual being a TT high-risk genotype of a GRM7 gene rs11928865 site. The application can non-invasively obtain brain image phenotype data related to GRM7 gene expression only by using a conventional magnetic resonance examination, significantly improves the specificity and interpretability of features, and provides high-confidence decision support for clinical non-invasive early warning.

The hearing loss correction system comprises a microphone unit, a speaker unit and a mobile phone inbuilt application processor to operatively connect the microphone unit with the speaker unit for recording environmental sound signal though the microphone unit and storage free direct streaming of said recorded sound signal to the speaker unit upon real time amplification and background noise suppression.

The invention provides application of p-hydroxycinnamic acid in preparation of a medicine for preventing and treating noise-induced deafness. The invention has the advantages that the p-hydroxycinnamic acid has the advantages of strong pertinence, high safety, convenience in medication, good patient compliance and the like, not only effectively overcomes the defects of the existing noise-induced hearing loss treatment medicines, but also provides a brand-new preventive treatment thought; important clinical popularization significance and industrial application prospects are realized.

To suppress hearing loss in players. [Solution] The pachinko machine 1 includes a speaker 22 and a performance control board 300 that can control the volume of sound output from the speaker 22 or from earphones owned by the player based on a custom volume value that can be changed according to the player's operation. When the volume value is a specific value, the volume of sound output from the earphones is lower than the volume of sound output from the speaker 22. This makes it possible to suppress hearing loss in the player.

A display device according to an embodiment of the present invention may comprise: a speaker; and a controller for transmitting a sound source to the speaker, receiving information including a plurality of hearing loss magnitudes of a user for a plurality of frequencies, respectively, comparing each of the plurality of hearing loss magnitudes with a first reference magnitude to obtain an inaudible frequency, the hearing loss magnitude of which is greater than or equal to the first reference magnitude, among the plurality of frequencies, and outputting, to the speaker, a compensation sound resource obtained by compensating the inaudible frequency among frequencies constituting the sound source.

A system and method of operating a hearing aid of a user includes receiving a mixed audio signal of multiple persons speaking and noise via a hand-held device microphone, the hand-held device such as a smartphone, being operationally connected to the hearing aid. The mixed audio signal is separated into individual speech streams of the persons speaking and the noise is attenuated. The individual speech streams are input into a voice-to-text application software to convert individual speech streams into text streams. Each individual text stream is displayed on a display screen of the hand-held device. The individual text streams on the hand-held device display are selected by the user to be transmitted as audio signals to the user's hearing aid. Lastly, the selected audio signals are amplified in the user's hearing aid while the non-selected speech streams and noise are attenuated.
