Abstract: A wearable sound therapy device includes a housing, and a loop cord coupled to the housing for supporting the sound therapy device pendant from the neck of a user upon a torso of the user. Audio electronics are resident in the housing and include a bone-conduction transducer, an audio file storage medium storing an audio file, a power supply, and a transducer control unit structured to energize the bone-conduction transducer based on the stored audio file to bone-conduct sounds to the body of the user. The stored audio file can include a compressed audio file such as an MP3 or MP4 file of pure tone sounds.
