Replaceable sound attenuating device detection

A hearing protection system, comprising:

• a computing system configured to estimate an effectiveness of at least one replaceable sound attenuating device, the at least one replaceable sound attenuating device comprising a sound attenuating material having a sensor element embedded therein;
• and
• an electronic receiver for the at least one replaceable sound attenuating device, the electronic receiver configured to:
• mate with the at least one replaceable sound attenuating device,
• determine a type of the at least one replaceable sound attenuating device based at least on a property of the sensor element as detected by the electronic receiver, and
• transmit, to the computing system over a communication link, an indicator that represents the type of the at least one replaceable sound attenuating device;
• wherein the computing system is configured to estimate the effectiveness of at least one replaceable sound attenuating device based at least on the indicator.

A method, comprising:

• detecting, by an electronic receiver for a replaceable sound attenuating device comprising a sound attenuating material having a sensor element embedded therein, a coupling between the electronic receiver and the replaceable sound attenuating device;
• determining, in response to detecting the coupling, a type of the replaceable sound attenuating device based on a property of the sensor element;
• receiving a command as part of an initial diagnostic test to estimate effectiveness of the replaceable sound attenuating device within a particular environment;
• and
• responsive to the command, transmitting an indicator that represents the type of the replaceable sound attenuating device to a computing system over a communication link.
