Abstract：Loop hearing aid is a hearing asistive service technology that uses an induction coil loop to provide magnetic field signals to hearing aids within thecoverage area.Hearing aid technology has become very popular in developed countries，and its application scope also covers the rail transit industry. However， there is still a significant gap in the specialized application of hearing aid technology，especially in the rail transit scene in China. Based on this，this paper puts forward adesign scheme of localized passenger hearing aid system terminal equipment for rail transit，introduces the principle and functions of this system，and emphaticaly analyzes its design scheme. The test verifies that the equipment has good performance，and users can get good hearing aid efects，realizing the independent design and production of passenger hearing aid products，and getting rid of the technical dependence on foreign enterprises.

Key words： rail transit; passenger hearing aid system;audio induction loop;passenger information system; Droadcasting system
