  • Patent number: 8333260
    Abstract: A deep insertion vented earpiece system is described including resilient earpieces shaped to a wearer's ear canal for a conformal fit. A receptacle is provided within the outer surface of each earpiece for releasably receiving an audio plug. The audio plugs include a miniature loudspeaker and a pair of external ribs for mating with a corresponding pair of grooves formed along the periphery of the receptacle. This rib and groove feature provides for a secure retention of the audio plugs while enabling a simple removal operation. Each earpiece includes an audio passage to conduct the audio signal from the loudspeaker and a vent passage to enable continuous venting of the wearer's ear to atmosphere.

  • Patent number: 8322222
    Abstract: A noise dosimeter with capability to rapidly predict noise exposure over an extended time period based on a measurement of short duration. Either an acoustic or an electrical earphone adapter provides a convenient means to connect the noise dosimeter to an external sound source. A direct input jack operable to receive at least one audio signal provides a signal to an RMS detector, which provides a DC signal to a two-stage amplifier circuit. The outputs of the amplifiers are provided to a processor having multiple A/D channels. The processor calculates accumulated noise doses and drives a display, which in one embodiment includes a panel of light-emitting diodes. In one embodiment, the dosimeter includes functionality for control of external devices such as sound boards.

  • Patent number: 8306237
    Abstract: This invention is a wearable device that masks and/or cancels annoying ambient sounds to help a person sleep. It includes a soft and stretchable member, such as a headband or hat, that contains one or more sound-conducting tubes. Sound that is emitted from the one or more tubes helps to mask and/or cancel annoying ambient sounds. Advantages of this device over prior art include: no speakers or other rigid components over a person's ears that can be uncomfortable or unsafe when the person sleeps on their side; a relatively wide sound-emitting area to accommodate different size and shape heads; and a stretchable wearable member that gently clings to the person's head to avoid having sound-emitting areas shift away from the person's ears as they toss and turn in their sleep.

  • Patent number: 8284974
    Abstract: A hearing aid comprises a microphone on a proximal side of a device housing and a loudspeaker which via a transmission channel is in open communication with a sound-emitting opening of the device. A sound processing device serves to generate sound received by the microphone to the loudspeaker in amplified form. The device housing is provided on a distal side with an optionally sealed battery chamber for receiving a battery therein. The transmission channel is at least almost wholly separated from the microphone acoustically in order to prevent acoustic feedback. The battery chamber comprises ventilation means for the purpose of increasing the lifespan of the battery.

  • Patent number: 8280093
    Abstract: A removable component for use with an earphone is disclosed. As an example, the removable component can be an ear tip. According to one aspect, an improved ear tip can be provided for use with a headphone. The ear tip is suitable for in-ear operation and can have a cosmetic deformable outer member. The deformable outer member can enable the ear tip to readily conform to a user's ear. The ear tip can also include an inner member to structurally support the outer member and to facilitate attachment to a headphone. Methods for forming such ear tips are also disclosed.

  • Patent number: 8218803
    Abstract: In the case of a receiver facility to be fixed in the auditory canal, particularly for hearing devices with an external receiver, the receiver is to be mounted in the earmold in an acoustically advantageous fashion which guards against contaminations and is also easily exchangeable. Provision is thus made for a receiver facility with a longish receiver and a earmold, which has a borehole, into which the receiver is inserted. A tubular connector, which is more elastic than the receiver and the earmold, is used to accommodate for the most part the longitudinal extension of the receiver in a friction-locking fashion. The connector is for its part force-fitted into a borehole of the earmold in a friction-locking fashion. The receiver is thus elastically mounted and can be easily removed from the earmold together with the connector with the aid of a pin-like tool for replacement purposes.
