Abstract: Sound devices such as hearing aids and headphones configured for intelligent information capturing are disclosed herein. In one embodiment, a sound device is a hearing aid or a noise-canceling headphone. The sound device includes a microphone, a speaker, a processor, and a memory containing a set of sound models each corresponding to a known sound. Upon receiving a digital sound signal representing an ambient sound captured via the microphone, the sound device can determine whether the digital sound signal includes a signal profile that matches the sound signature of one of the sound models stored in the memory. In response to determining that the digital sound signal has a signal profile that matches the sound signature of one of the sound models, the sound device can output, via the speaker, an audio message to the user identifying the known sound while suppressing the captured ambient sound from the environment.
