Classification: CPC A  H | IPC A

Claim 11:
12. An aural developmental medical device, comprising:
a first audio transducer device and a second audio transducer device that each transduce electrical signals into acoustic sounds;
at least one microphone device that transduces received acoustic sounds into electrical input signals;
electronics electrically coupled to the first audio transducer device, the second audio transducer device, and the at least one microphone device, wherein the electronics are operable to:
associate the aural developmental medical device with an identifier; and
receive the electrical input signals from the at least one microphone device;
electronically filter the electrical input signals to attenuate frequencies above a cutoff frequency that is at least octave above a fundamental frequency of a typical human voice to generate filtered electrical signals;
provide the filtered electrical signals to the first audio transducer device and the second audio transducer device;
generate recorded electrical signals from audio data encoding a recording and associated with the identifier; and
provide the recorded electrical signals to the first audio transducer device and the second audio transducer device;

a flexible packaging that positions the first and second audio transducer devices relative to each other so that the first and second audio transducer devices can be respectively positioned over a left ear and a right ear of an infant; and
an error detection device that monitors the frequency spectrum of the filtered electrical signals and generates an error signal when the monitoring of the frequency spectrum of the filtered electrical signals indicates frequencies above the cutoff frequency are not attenuated at least a threshold amount relative to frequencies below the cutoff frequency.
