Patent number: 8571224Abstract: In various embodiments, a system is used to provide an apparatus configured to measure sound in an ear canal of a wearer's ear at a distance from a tympanic membrane of the ear. The sound is measured and received by the apparatus to produce a signal. A frequency analysis is performed on the signal to determine output as a function of the frequency and to determine the frequency of the minima (null). Further, a distance equal to a quarter wavelength of the null frequency is calculated. A correction factor associated with the quarter wavelength is retrieved and applied to the output to generate a corrected output. An estimated sound pressure level at the tympanic membrane from the corrected output is produced.Type: GrantFiled: August 7, 2009Date of Patent: October 29, 2013Assignee: Starkey Laboratories, Inc.Inventors: Karrie LaRae Recker, Tao Zhang, Wei Li Lin

Publication number: 20130114839Abstract: An ear piece is formed for insertion and placement in an external auditory canal. The ear piece has an inflatable which, when it is inflated, expands and braces against the walls of the auditory canal. When it is deflated, it may be withdrawn from the auditory canal. The ear piece may be used in connection with a hearing aid, an MP3 player, a cell phone, or the like. A pump is provided for inflating the balloon and a valve may be controlled for selectively deflating the balloon. The air intake to the pump is disposed so as to be protected against contamination from inside the auditory canal. For that purpose it is formed inside a housing the air inlet of which is as far outside the ear canal as possible. In the case of a behind-the-ear application, the intake opening is formed in the housing that is to be placed behind the user's ear.Type: ApplicationFiled: April 8, 2011Publication date: May 9, 2013Applicant: SIEMENS MEDICAL INSTRUMENTS PTE. LTD.Inventor: Anton Gebert

Patent number: 8437492Abstract: An earpiece is provided containing a thermal activator layer comprised of a first polymer, the thermal activator layer being separated from the tympanic membrane of the user's ear by an air gap, and an acoustical reflector layer, containing a second polymer and pigment particles, adjacent to the thermal activator layer. The earpiece may be produced by sequential introduction of various liquefied components in layers within the ear canal, with the components being cured to provide the thermal activator layer and the acoustical reflector layer.Type: GrantFiled: March 18, 2011Date of Patent: May 7, 2013Assignee: Personics Holdings, Inc.Inventors: Steven Goldstein, John Patrick Keady, Paul Calvert

Patent number: 8437489Abstract: A hearing instrument with at least one microphone and signal processing includes at least two receivers having a different frequency response. At least a first one of the receivers can be placed outside the ear canal, for example in a behind-the-ear component. A behind-the-ear component and an external component can be provided for being placed in the user's ear canal or in the user's ear with a connection link between the behind-the-ear component and the external component. The sound processing means can feed the first receiver with a first signal of a first central frequency and the second receiver with a second signal of a second central frequency. The signal processing means can be one or two signal processing units. A frequency separating filter can have an input operatively connected to an output of the signal processing unit.Type: GrantFiled: October 25, 2010Date of Patent: May 7, 2013Assignee: Phonak AGInventors: Sven von Dombrowski, Hans Leysieffer, Bruno Gabathuler
