Abstract: Hearing excitation system for an eardrum (16), comprising a signal generator (17) and an optomechanical transducer (18) for exciting a vibration of an eardrum (16). The signal generator (17) is designed to emit a light signal (20) such that the light signal (20) hits the optomechanical transducer (18) and the light signal (20) triggers thermal deformation in the optomechanical transducer (18). The optomechanical transducer (18) is designed such that the thermal deformation causes a change in the curvature of the optomechanical transducer (18), as a result of which a surface portion (30, 31) of the optomechanical transducer (18) is deflected. The invention also relates to a method for operating a hearing excitation system.

Abstract: A method for operating an electro-acoustic system (11) arranges an electro-acoustic device (10), for occluding an ear canal on an ear and uses a signal processing device (16) for processing a signal incoming at the device (10). A correction unit (17) of the signal processing device (16) modifies the signal incoming at the device (10). To reduce, to avoid or to compensate for an interfering or undesired change in a perception of ambient noises during the use of an electro-acoustic device occluding the ear canal, with the correction unit (17), a signal outgoing from the device (10) is generated in order to achieve acoustic transparency, in which, on the basis of the outgoing signal, a received signal is generated at the eardrum which is adapted so as to correspond to a free-ear received signal at the eardrum in the case of a free ear canal without the device (10).
