Abstract: Embodiments of the present invention provide improved methods and apparatus suitable for use with hearing devices. A vapor deposition process can be used to make a retention structure having a shape profile corresponding to a tissue surface, such as a retention structure having a shape profile corresponding to one or more of an eardrum, the eardrum annulus, or a skin of the ear canal. The retention structure can be resilient and may comprise an anatomically accurate shape profile corresponding to a portion of the ear, such that the resilient retention structure provides mechanical stability for an output transducer assembly placed in the ear for an extended time. The output transducer may couple to the eardrum with direct mechanical coupling or acoustic coupling when retained in the ear canal with the retention structure.

Abstract: An output transducer is coupled to a support structure, and the support structure configured to contact one or more of the tympanic membrane, an ossicle, the oval window or the round window. An input transducer is configured for placement near an ear canal opening to receive high frequency localization cues. A sound inhibiting structure, such as an acoustic resistor or a screen, may be positioned at a location along the ear canal between the tympanic membrane and the input transducer to inhibit feedback. A channel can be coupled to the sound or feedback inhibiting structure to provide a desired frequency response profile of the sound or feedback inhibiting structure.

Abstract: Contact hearing devices for use with a wearable communication apparatus are disclosed to provide the user with an open ear canal to hear ambient sound and sound from an audio signal. The disclosed devices and systems have an advantage of providing sound to user from the audio signal, in many embodiments without creating sound that can be perceived by others. The contact hearing device can also be used to amplify ambient sound to provide a hearing assistance to users with diminished hearing. The wearable information apparatus can be configured to couple wirelessly to the contact transducer assembly, such that the wearable information apparatus can be removed while the contact transducer assembly remains placed on the user.

Abstract: A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.
