1. An earpiece comprising:
- an Ambient Sound Microphone (ASM) configured to capture ambient sound, the ambient sound containing an acute sound having an abrupt high energy sound profile;
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 at least one ECR, the processor being configured to;
monitor a change in an ambient sound level of the ambient sound,detect an on-set of a fast rising amplitude wave-front of the acute sound, andupon detecting the on-set of the fast rising amplitude wave-front of the acute sound, reproduce the acute sound within the ear canal via the ECR.

Abstract
Earpieces and methods for acute sound detection and reproduction are provided. A method can include measuring an ambient sound level external to an ear canal at least partially occluded by the earpiece, monitoring a change in the ambient sound level for detecting an acute sound, estimating a proximity of the acute sound, and reproducing the acute sound within the ear canal responsive to detecting the acute sound and the proximity.

14. An earpiece, comprising:
-
an Ambient Sound Microphone (ASM) configured to capture ambient sound, the ambient sound containing an acute sound having an abrupt high energy sound profile; at least one Ear Canal Receiver (ECR) configured to deliver audio to an ear canal; an audio interface configured to receive audio content; and a processor operatively coupled to the ASM, the at least one ECR, and the audio interface, the processor being configured to; monitor a change in an ambient sound level of the ambient sound, detect an on-set of a fast rising amplitude wave-front of the acute sound, adjust an audio content level (ACL) of the audio content delivered to the ear canal, and upon detecting the on-set of the fast rising amplitude wave-front of the acute sound, reproduce the acute sound within the ear canal via the ECR. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for acute sound detection and reproduction the method comprising:
-
measuring an ambient sound level (xASL) of ambient sound external to an ear at least partially occluded by an earpiece, the ambient sound containing an acute sound having an abrupt high energy sound profile; monitoring a change in the xASL of the ambient sound; detecting an on-set of a fast rising amplitude wave-front of the acute sound; and upon detecting the on-set of the fast rising amplitude wave-front of the acute sound, reproducing the acute sound within an ear canal. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
