The invention relates to a listening assistance device (1) comprising hearing modules (3) mounted on the ends of the arms of an eyeglass frame (2), said modules being designed to support the eyeglass frame on the ear of the user. The hearing modules also have a formed part (5) which extends into the auditive canal without closing the latter and which includes the sound outlet hole (6) of the module. The modules comprise a speech spectrum frequency response and linear dynamics in order to improve speech intelligibility. This makes it possible to provide a listening assistance device compensating for mild hearing loss that can be produced easily and economically, is more comfortable to use and is not regarded at first sight as a hearing aid by an observer.

The electronic ticket system according to claim 1, wherein at least said ticket public information and said ticket secret information constitute ticket characteristic information. 5. The electronic ticket system according to claim 4, wherein said ticket public information is made of a finite Abelian group, and said ticket secret information constitutes a annhilator area of said finite Abelian group. 6. The electronic ticket system according to claim 4, wherein said ticket secret information is an integer, and said ticket public information is a finite group, an element of said finite group, an order of said element, and a multiple of the element and secret information. 7. The electronic ticket system according to claim 1, wherein said proving device has internal state hold means for holding a variable internal state. 8. The electronic ticket system according to claim 7, wherein at least part of said variable internal state held by said internal state hold means of said proving device is protected against external attempts at modifying. 9. The electronic ticket system according to claim 7, wherein, during said interactive verification and said interactive proof, redundant information is transmitted at least once with respect to proof of knowledge about secret information. 10. The electronic ticket system according to claim 8, wherein said proving device has ticket counting means for holding information indicating an initialized internal state. 11. The electronic ticket system according to claim 10, wherein said proving device transmits at least once to said verification device information acquired from the internal state information of said proving device. 12. The electronic ticket system according to claim 11, wherein information acquired from that internal state information of said proving device which cannot be modified externally is transmitted at least once from said proving device to said verification device. 13. The electronic ticket system according to claim 8, wherein said internal state hold means of said proving device holds, in association with said ticket, an internal state indicating the validness of said ticket in a way that protects said internal state against external attempts at modifying; and wherein, if said internal state indicating the validness of said ticket takes a specific value, the corresponding ticket is judged to be invalid and information indicating invalidness of said ticket is transmitted during said interactive proof. 14. The electronic ticket system according to claim 13, wherein said verification device transmits information at least once to said proving device; and wherein, in accordance with the transmitted information from said verification device, said proving device changes the internal state which is associated with said ticket and which indicates the validness of said ticket, in order to either invalidate a valid ticket or validate an invalid ticket. 15. The electronic ticket system according to claim 8, wherein said internal state hold means of said proving device associates said ticket with an internal state acting as a ticket counter, said internal state being held so as to be protected against external attempts at modifying; wherein, during said interactive proof, an arithmetic operation is executed by use of said internal state acting as said ticket counter; and wherein, if said arithmetic operation results in a specific value, the corresponding ticket is judged to be invalid and information indicating the invalidness of said ticket is transmitted during said interactive proof. 16.
