Method and apparatus for scoring shooting events using hearing protection devices
First Claim
1. A system for scoring a shooting event for a shooter having a first ear and a second ear, the system comprising:
- a pair of hearing protection devices configured to protect hearing of the shooter from injurious sounds, the pair of hearing protection devices including;
a first ear device configured to be worn in or over the first ear, to detect gunshots, and to produce first detection information characterizing each of the gunshots as detected by the first ear device; and
a second ear device configured to be worn in or over the second ear, to detect the gunshots, and to produce second detection information characterizing each of the gunshots as detected by the second ear device; and
a portable device configured to be communicatively coupled to the pair of hearing protection devices, detect an acoustic signature using the first detection information and the second detection information, and identify each gunshot fired by the shooter from the gunshots detected by the first and second ear devices using the detected acoustic signature and a template signature, the template signature allowing for the identification of each gunshot fired by the shooter based on lengths of sound paths through which a sound of the gunshot being identified travels to the first ear device and the second ear device.

Abstract
A system for scoring a shooting event for a shooter includes a pair of hearing protection devices and a portable device. The hearing protection devices each include an electronic circuit that detects a gunshot and produces detection information characterizing the gunshot as detected. The difference between the detection information produced by the hearing protection devices worn in or over different ears of the shooter allows the portable devices to identify the gunshot as being fired by the shooter and subsequently prompt the shooter to give a voice command indicating the result of the gunshot to the portable device for the scoring without manual entry.

10. A method for scoring a shooting event for a shooter wearing a pair of hearing protection devices configured to protect hearing of the shooter from injurious sounds, the method comprising:
-
receiving detection information charactering each gunshot of gunshots detected by the pair of hearing protective devices; detecting an acoustic signature from the received detection information, the acoustic signature including one or more parameters allowing for identification of each gunshot fired by the shooter from the gunshots detected by the pair of hearing protective devices; determining whether the detected acoustic signature for the each gunshot matches a template signature; and identifying the each gunshot as being fired by the shooter in response to the determination that the detected acoustic signature for the each gunshot matches the template signature, wherein the template signature allows for the identification of the each gunshot as being fired by the shooter based on lengths of sound paths each being a path through which a sound of the each gunshot travels to one device of the pair of hearing protective devices. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A portable device for scoring a shooting event for a shooter wearing a pair of hearing protection devices including first and second ear devices configured to protect hearing of the shooter from injurious sounds, the portable device comprising:
-
a communication circuit configured to receive detection information regarding gunshots detected by the pair of hearing protection devices from the pair of hearing protection devices via a wireless link, the detection information including or derived from first detection information characterizing each of gunshots as detected by the first ear device and second detection information characterizing the each of the gunshots as detected by the second ear device; and a processing circuit configured to identify an acoustic signature using the detection information and identify each gunshot fired by the shooter from the gunshots detected by the pair of hearing protection devices in response to the identified acoustic signature matching a template signature, the template signature allowing for the identification of each gunshot fired b the shooter based on lengths of sound paths through which a sound of the gunshot being identified travels to the first and second ear devices. - View Dependent Claims (18, 19, 20, 21)
