    Abstract: A personal listening system and a method of using the personal listening system to enhance speech intelligibility of audio playback, are described. The method includes determining a speech intelligibility metric, such as a speech reception threshold, of a user. Based on the speech intelligibility metric, a tuning parameter is applied to an audio input signal. The speech reception threshold is compared to an environmental signal-to-noise ratio to determine whether enhancement of the audio input signal is warranted. Application of the tuning parameter to the audio input signal generates an audio output signal having reduced noise, making playback of the audio output signal more intelligible to the user. Other aspects are also described and claimed.

    Abstract: An earphone comprising an earphone housing having a wall comprising (1) a front side that joins (2) an end portion in which a primary sound output opening is formed, which joins (3) a face portion in which a secondary output opening is formed, which joins (4) a back side which joins the front side and encloses a driver, wherein the primary output opening is dimensioned to output sound generated by a diaphragm of the driver contained within the earphone housing into the ear and the secondary output opening is dimensioned to vent the ear to a surrounding environment, and wherein the primary output opening and the secondary output opening face different directions.

    IPC: H04R25/00

    Abstract: A media system and a method of using the media system to accommodate hearing loss of a user, are described. The method includes selecting a personal level-and-frequency dependent audio filter that corresponds to a hearing loss profile of the user. The personal level-and-frequency dependent audio filter can be one of several level-and-frequency-dependent audio filters having respective average gain levels and respective gain contours. An accommodative audio output signal can be generated by applying the personal level-and-frequency dependent audio filter to an audio input signal to enhance the audio input signal based on an input level and an input frequency of the audio input signal. The audio output signal can be played by an audio output device to deliver speech or music that the user perceives clearly, despite the hearing loss of the user. Other aspects are also described and claimed.
