Publication number: 20120321094Abstract: A personal noise monitoring system and method for operating the same. Sound pressure data from inside the ears of a user of hearing protection device (HPD) are acquired from microphones in the HPD and reported to a master control unit. Simultaneously, the master control unit receives sound pressure data from the ambient environment in which the user is located. The data are reported to a central server for processing. The central server may use the data to determine in near real time or real time whether the user of the HPD is at risk for exposure to excess sound levels and to take remedial action while the user is still in the ambient environment.Type: ApplicationFiled: June 5, 2012Publication date: December 20, 2012Applicant: Adaptive Technologies, Inc.Inventors: Ean H.

Patent number: 7854294Abstract: An earmuff assembly with a double-shell structure is disclosed for use with a sound-attenuating circumaural headset. The earmuff assembly comprises a cup-shaped outer shell mounted on a resilient outer sealing ring and a cup-shaped inner shell mounted on a resilient inner sealing ring. By means of the two sealing rings the outer and the inner shells are brought into abutment with the head surface around an ear of a wearer. Both shells are structurally rigid. The sound attenuation performance is maximized by isolating the inner shell from the outer shell.Type: GrantFiled: January 22, 2010Date of Patent: December 21, 2010Assignee: Adaptive Technologies, Inc.Inventors: Yu Du, Kenji Homma, Michael A.

Patent number: 7308106Abstract: A tailored active noise control design method is presented that provides for improved noise attenuation performance for each individual user and improved hearing protection in a specified noise field as a function of a specified metric indicative of a noise reduction objection. Characteristics of individual users, behavior of the associated passive hearing protection, and the external noise environment are all concurrently accounted for in an automatic method for designing an active controller that limits the exposed noise level for a specific individual. The controller manufacturing process and implementation may be performed in-situ for each individual automatically. The design method may also account for actuator limitations and can be applied equally well to any passive/active noise control devices including headphones and earplugs.Type: GrantFiled: May 17, 2004Date of Patent: December 11, 2007Assignee: Adaptive Technologies, Inc.Inventors: Michael A.

Patent number: 7245726Abstract: A microphone housing improves the broadband noise canceling performance of an active noise canceling microphone system while also ensuring improved speech transmission through the system. First and second microphone elements are selected each having a diameter “d” and a thickness “t”. The two microphone elements are aligned axially with the back surfaces in contact and secured in an axially aligned cylindrical cavity within a cylindrically shaped housing. The cylindrically shaped housing has an outside diameter “D,” an interior cavity of diameter of “d,” and a height “2t”. The housing is exposed to an environment comprising both speech and noise. The first microphone element is adapted to receive a signal having both voice and noise components, while the second microphone element is adapted to receive a signal that is predominantly noise. A controller processes signals from the first microphone element and the second microphone element.Type: GrantFiled: August 27, 2004Date of Patent: July 17, 2007Assignee: Adaptive Technologies, Inc.Inventors: Yu Du, Michael A.

Patent number: 7206425Abstract: An actuator for use with active noise control (ANR). The present invention satisfies design goals commensurate with active noise reduction devices used in small enclosed volumes and moderate-to-high noise environments. An ANR voice coil speaker is cylindrical in shape, with a diaphragm to motor diameter less than unity and fits into the ear canal. The rear cavity volume is on the same order of magnitude as the volume of the front cavity defined by the space between the diaphragm and the eardrum. The relatively balanced front/back volume of the ANR speaker reduces the required force to achieve a specific displacement required for high sound pressure output. An ANR balanced armature actuator uses a modified cabinet design, and a segmented or stiffened diaphragm made of light materials, and a sheet-type coupling between the armature and the diaphragm to reduce or eliminate resonances and phase lag within a desired control band.Type: GrantFiled: January 21, 2004Date of Patent: April 17, 2007Assignee: Adaptive Technologies, Inc.Inventors: Michael A.
