Abstract: An apparatus provides a quick and easy way too store smart headphones while preserving headphone battery life. A trigger element such as a magnet is positioned so that a sleep/wake system in the headphones detects its proximity when stored on the apparatus. In an exemplary embodiment, the apparatus is configured so that the headphones are hung in an open-air setting which makes them easily accessible for use without having to be retrieved from a closed container. When mounted, the trigger element may signal the headphones to enter a sleep mode to preserve battery life. Once removed, the headphones may detect the lack of proximity to the trigger element which frees the headphones for operation.

Abstract: Hearing aids for persons with sensorineural hearing loss aim to compensate for degraded speech perception caused by frequency-dependent elevation of hearing thresholds, reduced dynamic range, abnormal loudness growth, and increased temporal and spectral masking. A digital hearing aid is implemented as a smartphone application as an alternative to ASIC-based hearing aids. The implementation provides user-configurable processing for background noise suppression and dynamic range compression. Both processing blocks are implemented for real-time processing using single FFT-based analysis-synthesis. A touch-controlled graphical user interface enables the user to set and fine-tune the processing parameters in an interactive and real-time mode.
