Abstract

Hearing assistive apparatus can be implemented to include sound replay capability, the hearing assistive apparatus enabling operation in a replay mode (in which the hearing assistive apparatus replays sound that occurred prior to the current time), as well as in a current sound mode (in which the hearing assistive apparatus reproduces—and, typically, enhances—sound as the sound occurs) and/or an off mode (in which the hearing assistive apparatus does not produce sound). The hearing assistive apparatus can also, additionally or alternatively, be implemented so that part of the hearing assistive apparatus is spatially separated from another part of the hearing assistive apparatus (in particular, so that part of the hearing assistive apparatus is spatially separated from part of the hearing assistive apparatus that is ear-mounted).
