    Abstract: Systems for magnetoacoustically transferring sound across an acoustic barrier include first and second acoustic resonators positioned on opposite sides of the barrier. Each of the first and second resonators includes an attached magnet. Via magnetic coupling between the magnets, an acoustic oscillation at the first resonator induces an oscillation of the same frequency at the second resonator. Thus sound waves absorbed at the first resonator are magnetically transferred across the barrier to the second resonator, from which they are emitted.

    Abstract: Workplace safety is a principal concern in many environments. Protecting user ears from damage due to extended exposure to unacceptably high sound volume serves as an important component to workplace safety. Monitoring a device, such as a phone, utilized by a user often provides an incomplete picture of the sound level presented to the user. As provided herein, monitoring a user's sound exposure on one device may cause the sound level presented to the user from a second device to become limited. Additionally, over time the sound level limits may be adjusted based on the cumulative historic sound exposure. As a result, the user may avoid exposure to unacceptably high sound levels originating from more than one source and/or over an extended period of time.

  • Patent number: 11330388
    Abstract: An audio customization system operates to enhance a user's audio environment. A user may wear headphones and specify what portion the ambient audio and/or source audio will be transmitted to the headphones or the personal speaker system. The audio signal may be enhanced by application of a spatialized transformation using a spatialization engine such as head-related transfer functions so that at least a portion of the audio presented to the personal speaker system will appear to originate from a particular direction. The direction may be modified in response to movement of the personal speaker system.

  • Patent number: 11321912
    Abstract: A system and method for generating a full three-dimensional (3D) digital geometry for an ear provides a 3D reconstruction model that not only includes the outer area of an ear, but also the inner canal area up to the second bend. The system includes at least one remote server and a PC device. The remote server manages and processes data needed for the 3D model for an ear. The PC device allows a user to access the system and method. The remote server processes a series of video frames to generate outer ear 3D data points. Full ear geometry 3D data points are generated by comparing the outer ear 3D data points with a plurality of ear impressions. Canal 3D data points are then adjusted with a tragus angle for accuracy. The 3D reconstruction model that includes the outer ear area and inner canal area is finally generated.

  • Patent number: 11303998
    Abstract: Disclosed herein are techniques for determining a wearing position of a boomless headset. An earpiece of the boomless headset can include at least one local talker (LT) microphone and a reference microphone. The LT microphone(s) are disposed substantially in a first end of the earpiece closest to a mouth of a LT when the LT wears the earpiece. The reference microphone is disposed substantially in a second end of the earpiece, furthest from the mouth of the LT when the LT wears the earpiece. A signal strength measurement (SSM) for a local talker audio signal to the LT microphone(s) and a SSM for a signal to the reference microphone are obtained. Signal processing logic can determine whether the earpiece is worn at an incorrect ear based on whether a difference between the SSM for the LT microphone(s) and the SSM for the reference microphone is below a predetermined threshold.
