A method and system for enhancing speech intelligibility using wireless communication in portable, battery-powered and entirely user-supportable devices. The devices may be talker devices and receiver devices, where the audio signals input into the talker devices may be transmitted to the receiver devices to provide better quality audio to person using the receiver devices. The receiver devices may initiate and terminate communications with the talker devices. Additionally, the receiver devices may indicate to the talker devices the gain level the talker devices need to apply to the audio signals before sending them to the receiver devices.

An insert high fidelity earphone is provided in which a hollow housing is connected to two tubes. A first tube is connected to the hollow housing on one side, and on the other side is inserted into an ear tip that ensures substantial sealing of the ear canal. A second tube is connected to hollow housing on one side and houses a cable that connects circuitry in the hollow housing to an audio source. The first tube comprises a damping assembly. The first tube comprises grooves on the inside wall that ensure that the damping assembly only fits in one orientation, which is the correct orientation. The damping assembly may be easily replaceable, without having to replace the entire earphone. The earphone may have a curved shape providing a comfortable and nearly invisible fit into the ear canal.

Certain embodiments of the invention may be found in an insert earphone assembly. The insert earphone assembly may comprise a housing and a transducer located in the housing. The transducer may be for converting electrical signals received into sound energy. The insert earphone apparatus may further comprise an insert element. The insert element may be at, least partially integrated within the housing. The insert element may also comprise a main sound channel for communicating the sound energy from the transducer to a user. In certain embodiments, one or more of the body and the insert element may comprise one or more auxiliary ducts and one or more auxiliary volume spaces. The one or more auxiliary ducts and one or more auxiliary volume spaces may be separated by one or more auxiliary dampers. In certain embodiments, a diameter, length and/or shape of the one or more auxiliary ducts or one or more auxiliary volume spaces may be adjusted so as to modify an insertion response characteristic of the insert earphone assembly.

A microphone assembly generally for hearing aid and communications applications is disclosed. The microphone assembly operates in both directional and non-directional or omni-directional modes. The microphone assembly has front and rear sound inlet tubes, and an actuator switch that may be moved between a first position in which the rear tube is plugged, defining the omni-directional mode, and a second position in which the rear tube is unplugged, defining the directional mode. Circuitry senses the position of the actuator switch and selects a microphone output based on the position sensed.

A hearing-aid device comprising a housing and circuitry module, wherein the circuitry module comprises a battery, a microphone, and a receiver, and the circuit module is inserted in the hearing aid housing. The hearing aid device further comprises a retractable battery sleeve, wherein a battery slot is exposed when the battery sleeve is retracted, and a battery can be inserted into the battery slot from either side of the battery slot with either polarity. The hearing aid housing may comprise an ear-tip, wherein a microphone is mounted in the hearing aid housing near the ear-tip and the microphone receives sounds through at least one sound inlet located on a side surface of the hearing aid housing. The ear-tip additionally comprises three flanges decreasing in size toward the flange closest to the ear canal, and the hearing aid can be inserted into the ear canal in any orientation.
摘要:
A personal noise dosimeter having functionality for increasing the dynamic range of the device. A microphone 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. A current source injects current into the output of the RMS detector to reduce performance degradation. Functionality detects and accounts for voltage offsets in the dosimeter. The microphone is turned off during offset determination. In one embodiment, the dosimeter includes functionality for control of external devices such as sound boards.

A power supply circuit is set forth which overcomes the problems associated with incorrect battery insertion. The power supply circuit includes first and second battery terminals for electrical connection to the battery. The first and second battery terminals are connected to a first transistor switching circuit. The first transistor switching circuit is responsive to power from the battery to through-connect a negative polarity power signal therethrough irrespective of the polarity orientation of the battery. The first and second battery terminals are also connected to a second transistor switching circuit. The second switching circuit is responsive to power from the battery to through-connect a positive polarity power signal therethrough irrespective of polarity orientation of the battery. The negative and positive polarity power signals are available for connection to a load device, such as a hearing aid amplifier. The device is thereby provided with proper power polarity irrespective of the way in which the battery is inserted between the first and second battery terminals. The power supply circuit is implemented in an integrated circuit format and is mounted with a chip capacitor.
