1. A system, comprising:
- a microphone;
a memory that stores instructions;
a processor that executes the instructions to perform operations, the operations comprising;
estimating a background noise level (BNL) of an environment;
identifying a peak level (SPL) stored in an audio buffer including an external ambient sound, wherein the SPL is of the external ambient sound;
generating a SPL-BNL difference by subtracting the BNL from the SPL identified in the audio buffer;
comparing the SPL-BNL difference to a threshold to determine if a sound has been detected; and
detecting the sound when the SPL-BNL difference is greater than the threshold.

Abstract
Earpieces and methods for acute sound detection and reproduction are provided. A method can include measuring an external ambient sound level (xASL), monitoring a change in the xASL for detecting an acute sound, estimating a proximity of the acute sound, and upon detecting the acute sound and its proximity, reproducing the acute sound within an ear canal, where the ear canal is at least partially occluded by an earpiece. Other embodiments are disclosed.

12. A method, comprising:
-
estimating a background noise level (BNL) of an environment; identifying a peak level (SPL) stored in an audio buffer including an external ambient sound, wherein the SPL is of the external ambient sound; generating, by utilizing instructions from a memory that are executed by a processor, a SPL-BNL difference by subtracting the BNL from the SPL identified in the audio buffer; comparing the SPL-BNL difference to a threshold to determine if a sound has been detected; and detecting the sound when the SPL-BNL difference is greater than the threshold. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A device, comprising:
-
a memory that stores instructions; a processor that executes the instructions to perform operations, the operations comprising; estimating a background noise level (BNL) of an environment; identifying a peak level (SPL) stored in an audio buffer including an external ambient sound, wherein the SPL is of the external ambient sound; generating a SPL-BNL difference by subtracting the BNL from the SPL identified in the audio buffer; comparing the SPL-BNL difference to a threshold to determine if a sound has been detected; detecting the sound when the SPL-BNL difference is greater than the threshold; and passing the sound to an ear canal receiver if the sound is determined to not be user-generated.
