We introduce HomeSound, an in-home sound awareness system for Deaf and hard of hearing (DHH) users. Similar to the Echo Show or Nest Hub, HomeSound consists of a microphone and display, and uses multiple devices installed in each home. We iteratively developed two prototypes, both of which sense and visualize sound information in real-time. Prototype 1 provided a floorplan view of sound occurrences with waveform histories depicting loudness and pitch. A three-week deployment in four DHH homes showed an increase in participants' home- and self-awareness but also uncovered challenges due to lack of line of sight and sound classification. For Prototype 2, we added automatic sound classification and smartwatch support for wearable alerts. A second field deployment in four homes showed further increases in awareness but misclassifications and constant watch vibrations were not well received. We discuss findings related to awareness, privacy, and display placement and implications for future home sound awareness technology.
