1. An acoustic device, comprising:
- an Ambient Sound Microphone (ASM) configured to capture ambient sound;
at least one Ear Canal Receiver (ECR) configured to deliver audio to an ear canal; and
a processor operatively coupled to the ASM and the ECR, where the processor monitors the ambient sound for a target sound and adjusts the audio delivered to the ear canal based on the target sound, the processor generating a sound signature from the ambient sound and comparing the sound signature to a plurality of learned signature models to detect the target sound.

Abstract
Methods for personalized listening which can be used with an earpiece are provided. A method includes capturing ambient sound from an Ambient Sound Microphone (ASM) of an earpiece partially or fully occluded in an ear canal, monitoring the ambient sound for a target sound, and adjusting by way of an Ear Canal Receiver (ECR) in the earpiece a delivery of audio to an ear canal based on a detected target sound. A volume of audio content can be adjusted upon the detection of a target sound, and an audible notification can be presented to provide a warning.

16. A method for sound signature detection, the method comprising:
-
capturing ambient sound with an Ambient Sound Microphone (ASM); and receiving a directive to learn a sound signature within the ambient sound, where a voice command or an indication from a user is received and is used to initiate the steps of capturing and learning. - View Dependent Claims (17)

18. A method for personalized listening, the method comprising:
-
capturing ambient sound via an earpiece that is at least partially occluded in an ear canal; detecting a sound signature within the ambient sound that is associated with a target sound; and mixing the target sound with audio content delivered to the earpiece in accordance with a priority of the target sound and a personalized hearing level (PHL), where learned models are retrieved from a database, the sound signature is compared to the learned models, and the target sound is identified from the learned models in view of the comparison. - View Dependent Claims (19)

20. A sound detection device comprising:
-
an ambient sound microphone configured to measure an ambient sound; an ear canal microphone; and a processor configured to compare the ambient sound to at least one target sound signature, and where the processor identifies an onset of an identified target sound signature in the ambient sound, where the ear canal microphone is configured to emit an auditory warning when the processor identifies the onset. - View Dependent Claims (21)
