Patent ID: 8254587

Claim:
An apparatus for assessing in-situ an acoustic seal of an in-ear device, the in-ear device having a passageway extending therethrough, the passageway being in fluid communication with an ear canal of an ear when the in-ear device is inserted therein, said apparatus comprising: a controller unit operatively connectable to a sound source; a sound measurement device operatively connecting to said controller unit, said sound measurement device being selectively locatable in a close relationship relative to the in-ear device and outside the ear canal for measuring a first sound level outside the ear canal when submitted to the sound source, said sound measurement device being removably engageable into the passageway to selectively occlude the passageway for measuring a second sound level inside the ear canal with the in-ear device inserted therein when submitted to the sound source; and a supporting device for releasably supporting said sound measurement device located in a close relationship relative to the sound source for measuring a reference sound level when being submitted thereto, wherein the supporting device is mountable on the sound source, releasably supporting the sound measurement device thereon.
