Beschreibung
Zusammenfassung:	The invention relates to a magnetic induction antenna for transmitting audio signals to a person who is hard of hearing and wears a hearing aid, said antenna comprising a copper loop. The antenna of the invention is unique in that it is produced in the form of a printed circuit on a flexible or rigid substrate, and comprises a copper track forming multiple adjacent turns on said substrate, and in that the length and the height of the copper track determine an antenna impedance of approximately 32 Ω which is compatible with a headphone jack of an electronic device. The invention also relates to the integration of said antenna into a removable magnetic-loop audio transmission system. The invention also relates to a seat comprising the antenna of the invention in a headrest of said seat. The invention also relates to a cabin of a passenger transport vehicle comprising a system or a seat according to the invention.
