摘要： A hearing aid system includes a Bluetooth enabled sound output device and Bluetooth enabled sound output device. The sound output device has a first processor coupled to a first memory, to a first Bluetooth module, to a sound processing module including an amplifier and a speaker, and to a first power supply. The sound input device has an optional aux jack, and a second processer coupled to a second memory, to a second Bluetooth module selectively Bluetooth linkable with the first Bluetooth module, to a sound input module, and to a second power supply. The sound input device may adjust audio volume level of audio signals to a default level before transmission to the sound output device. A second sound input device may transmit audio signals based to the sound input device, from which the audio signals are transmitted to the sound output device.

摘要： An equalized hearing aid system includes a microphone, a first equalizer, a first mixer, and a first speaker coupled in series forming a first signal path with a second mixer coupled to the first equalizer within the first signal path. The microphone, a second equalizer, a third mixer, and a second speaker are coupled in series forming a second signal path with a fourth mixer coupled to the second equalizer within the second signal path. A control interface may be coupled to at least one of the first equalizer and the second equalizer. A Bluetooth module may be coupled to at least one of the first equalizer and the second equalizer. A third equalizer may be coupled to input signal into the first signal path and a fourth equalizer may be coupled to input signal into the second signal path.

摘要： An iontophoresis device may include a flexible support layer, an electrode layer, having at least two electrically isolated electrodes, fixed to the support layer. A return electrode is separated from the electrode layer and the flexible support layer. A control module is detachably connected to the electrode layer and to the return electrode. The control module is configured to provide a variable current source or a variable voltage source only to a selected proper subset of the at least two electrically isolated electrodes while not providing the variable current source to other electrodes of the at least two electrically isolated electrodes.
