HEARING DEVICE WITH EAR MONITORING FUNCTION |
摘要 |
According to an aspect, a hearing device adapted to be worn at an ear of a user for in-situ monitoring of a middle ear of the user is disclosed. The hearing device includes a receiver adapted to direct an incident electrical acoustic signal of a predetermined level and a predetermined frequency toward a tympanic membrane of the user; a measurement microphone adapted to covert a reflected sound signal that is reflected from the tympanic membrane in response to the incident electrical acoustic signal to a reflected electrical acoustic signal; a comparator adapted to calculate a level difference between the predetermined level and a reflected level of the reflected electrical acoustic signal; and a notification generator adapted to generate an indicator signal representative of status of the middle ear of the user if the level difference is equal or more than a predetermined threshold level. |

1. A hearing device adapted to be worn at an ear of a user for in-situ monitoring of a middle ear of the user, the hearing device comprising
a receiver adapted to direct an incident electrical acoustic signal of a predetermined level and a predetermined frequency toward a tympanic membrane of the user; a measurement microphone adapted to covert a reflected sound signal, reflected from the tympanic membrane in response to the incident electrical acoustic signal, to a reflected electrical acoustic signal; a comparator adapted to calculate a level difference between the predetermined level and a reflected level of the reflected electrical acoustic signal; and a notification generator adapted to generate an indicator signal representative of status of the middle ear of the user if the level difference is equal or more than a predetermined threshold level. |
