1. An earpiece, comprising:
an ambient microphone configured to measure the ambient sound near the entrance to a user's ear canal;
an internal microphone configured to measure the sound within the user's ear canal;
a user interface;
a memory that stores instructions;
an expandable element configured to contain a non-Newtonian fluid wherein the non-Newtonian fluid is a fluid wherein the viscosity of the fluid increases when an acoustic pressure against it increases and wherein the viscosity of the fluid reduces when the acoustic pressure against it is reduced;
an inflation management system configured to move non-Newtonian fluid into and out of the expandable element;
a controller, wherein the controller is configured to execute the instructions to perform operations comprising:
receiving an activation signal from the user interface and activating the inflation management system;
sending a signal to the inflation management system to move non-Newtonian fluid into the expandable element; and
sending a signal to the inflation management system to stop non-Newtonian fluid movement when a threshold comfortable pressure level is reached.
