1. A device comprising:
- a sealing section configured to seal a user'"'"'s orifice, where the sealing section is configured to produce an acoustic seal between a first side of the sealing section and a second side of the sealing section;
a transducer configured to generate a first acoustic signal incident on the first side of the sealing section; and
a first microphone configured to measure a second acoustic signal incident on the second side of the sealing section, where the second acoustic signal includes at least a portion of the first acoustic signal that has passed from the first side to the second side of the sealing section where the first acoustic signal is compared to the second acoustic signal to determine if the sealing section is sealed.

Abstract
A test signal emitted by an earpiece is compared against the acoustic signal to determine if a sealing section of the earpiece is sealed properly. The degree of acoustic sealing is used to adjust the attenuation level of a sealing section of the earpiece or alert the user of the seal status of the sealing section.

10. A method of detecting whether a sealing section of an earpiece is sealed comprising the steps of:
-
generating a first acoustic signal incident on a first side of the sealing section; measuring a second acoustic signal incident on a second side of the sealing section, where the second acoustic signal includes at least a portion of the first acoustic signal that has passed from the first side to the second side of the sealing section; and comparing the first acoustic signal to the second acoustic signal to determine if the sealing section is sealed. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of detecting whether a sealing section of an earpiece is sealed comprising the steps of:
-
generating a first acoustic signal incident on a first side of the sealing section; measuring a second acoustic signal incident on a second side of the sealing section, where the second acoustic signal includes at least a portion of the first acoustic signal that has passed from the first side to the second side of the sealing section; correlating the first acoustic and second acoustic signals; and comparing the correlation to a threshold where the earpiece is sealed improperly if the threshold is exceeded. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
