- the second bone conduction device in contact with a second bone zone of the user's head, the second bone zone being different from the first bone zone, and the first and the second bone zones being located around a same ear,
- the method makes it possible to stimulate, by means of two bone conduction devices positioned at specific points of the user's anatomy, two different parts of the auditory nerve.
- the process makes it possible to restore the entire auditory spectrum to the user, unlike a device that would use a single point of bone conduction.
- a bone conduction device when it is indicated that a bone conduction device is positioned around the ear, this means that it is positioned in contact with bone parts located around said ear, and this, preferably 3 cm at most from a point on the circumference of the ear to which it is closest, preferably 2 cm at most.

- the first and/or the second bone zones is (are) chosen so as to be able to transmit the determined frequency ranges to the user; thus, the positioning of the first and of the second devices can be adapted so as to the user's needs and also to his morphology; advantageously, it is thus possible to transmit all the frequencies of the auditory spectrum or to favor certain frequencies according to the degree of hearing loss of the user;
- the first device can be positioned in contact with the temporal bone, and preferably in contact with the mastoid process of the temporal bone; advantageously, the mastoid process of the temporal bone makes extensive contact with the auditory nerve and the first vibrations transmitted by this part of the temporal bone thus stimulate an extended part of the auditory nerve; moreover, the mastoid process of the temporal bone preferentially transmits frequencies ranging from very low to medium; and
- the second device can be positioned in contact with the temporal bone and/or the mandible; when the second device is in contact with the temporal bone, it is preferably close to the temporomandibular joint, namely for example at most 3 cm from said joint and preferably at most 2 cm; the temporal bone preferably transmits frequencies ranging from medium low to very high.

In the case where the hearing system is used for example for a conversation with a third person, or to listen to music, the hearing system allows the user to have stereo sound.
- the invention also relates to a hearing aid for its use in the treatment of hard of hearing and deafness, said hearing aid comprising at least a first bone conduction device and at least a second bone conduction device, the first device being configured to be positioned in contact with a first bony zone of the user's head and for transmitting first vibrations to said first bony zone, and the second device being configured to be positioned in contact with a second zone of the user's head and for transmitting second vibrations to said second bone area, said second area being different of the first zone, and said first bony zone and said second bony zone being located around one and the same ear of the user, said hearing aid further comprising at least one microphone making it possible to pick up a surrounding sound signal which is then transformed to generating the first and second vibrations.
- the hearing aid may be such as that described according to the first object of the invention.

- the first microphone 10 is oriented towards the front of the user and the second microphone 10' is oriented towards the rear of the user.
- the first and second microphones 10 and 10' pick up different and complementary sound signals.
- the central unit 6 also comprises a processing module 9 comprising, as in the first variant, a processor 11.
- the processor 11 makes it possible to superimpose the electrical signals coming from the first and second microphones 10 and 10' in order to form an overall electrical signal which is then transmitted to the first and to the second transducers 12 and 13.
- first bone conduction device 2 and 3 are identical to those described in the first variant and are positioned around the user's ear as described for the first variant.
- the hearing aid is more compact and less bulky and therefore more practical to use.
- the two microphones being positioned near the ear and being oriented differently, the device reproduces very realistically the sound normally perceived by the ear.
- FIG. 2a illustrates a hearing aid 21 according to a second embodiment.
- the hearing aid 21 includes a first bone conduction device 22 and a second bone conduction device 23.
- the first and the second devices 22 and 23 are connected to each other by a connecting device 4 which also serves as a system for holding the first and the second device 22 and 23.
- the connecting device is a relatively rigid hoop which matches the contour of the ear 5 and which maintains the first and the second devices 22 and 23 in a relatively fixed position with respect to each other.
- Figure 2b illustrates an enlarged view of a first part 4' of the connecting device 4 in which are placed the various elements making it possible to generate first vibrations 34.
- the connection device 21 comprises a first microphone 30, a processing module 32 comprising a microprocessor 31 and a first transducer 33.
- the connection device 21 also comprises a battery 27 making it possible to supply the various aforementioned elements.
- the link device 21 also includes a wireless connection system 26 that can allow, for example, to receive a secondary electrical signal from a mobile phone or a music player. This secondary electrical signal can be processed by the microprocessor 31 then be transmitted to the first and to the second transducer 33 and 33' and thus be transformed into first vibrations 34 and second vibrations 35.
- the hearing aid comprises only one of the following elements: microphone 30, microprocessor 32 and battery 27.
- the hearing aid 21 may comprise each of these elements in duplicate, the second element of each being positioned in a second part of the connecting device 21, close to the second bone conduction device 23.
- FIG 3 illustrates a third embodiment of the invention.
- This embodiment relates to a hearing system 50 which includes a first hearing aid 41 and a second hearing aid 41'.
- Each hearing aid 41 (41') includes a first bone conduction device 42 (42') and a second bone conduction device 43 (43').
- Each hearing aid also includes the elements for receiving and processing the sound signal (microphone, microprocessor and transducer) as in the second embodiment which are placed in the holding system 52 taking the form of a helmet.
- This third embodiment can for example be used as a noise-canceling helmet making it possible not to hear surrounding noise but making it possible to receive an electrical signal coming for example from a music player or the words of a third person by telephone.
- This type of helmet can be used for example by workers in the construction industry. According to this use, it is possible to process the sound signal in such a way that the noise is reduced or even eliminated, and that the user can still hear the instructions of a person around him.
- Figure 4 illustrates a method 100 of listening to a surrounding sound signal by means of the hearing aid 1. This method comprises:
