At least one exemplary embodiment is directed to a method of earphone feature control by using a graphic user interface on a device linked to the earphone.

Earphone software and hardware

At least one exemplary embodiment is directed to a method and device for voice operated control with learning. The method can include measuring a first sound received from a first microphone, measuring a second sound received from a second microphone, detecting a spoken voice based on an analysis of measurements taken at the first and second microphone, learning from the analysis when the user is speaking and a speaking level in noisy environments, training a decision unit from the learning to be robust to a detection of the spoken voice in the noisy environments, mixing the first sound and the second sound to produce a mixed signal, and controlling the production of the mixed signal based on the learning of one or more aspects of the spoken voice and ambient sounds in the noisy environments.

Method and device for voice operated control

A method and device for automatically increasing the spectral bandwidth of an audio signal including generating a 'mapping' (or “prediction”) matrix based on the analysis of a reference wideband signal and a reference narrowband signal, the mapping matrix being a transformation matrix to predict high frequency energy from a low frequency energy envelope, generating an energy envelope analysis of an input narrowband audio signal, generating a resynthesized noise signal by processing a random noise signal with the mapping matrix and the envelope analysis, high-pass filtering the resynthesized noise signal, and summing the high-pass filtered resynthesized noise signal with the input narrowband audio signal. Other embodiments are disclosed.

Method and device for spectral expansion of an audio signal

A control device configurable to couple to one or more devices having different control functions and a method of facilitating remote control of at least one device having different control functions includes a processor that receives an instruction for at least one of the control functions and additional information from the at least one device, the processor including a plurality of processing algorithms, the additional information received from the at least one device including at least a locally transmitted data signal. The processor selectably processes the additional information using at least one of the processing algorithms and controls a touch sensitive display reconfigurable for the different control functions, such that the at least one control function and the selectably processed additional information are presented on the touch sensitive display. The processor also generates at least one control signal responsive to receiving the locally transmitted data signal. Other embodiments are disclosed.

Designer control devices

At least one exemplary embodiment is directed to a method of generating a hearing impairment compensation function to process audio reproduced by an earphone device. The compensation function includes processing the audio to compensate for frequency sensitivity to improve speech intelligibility.

Method to estimate hearing impairment compensation function

At least one exemplary embodiment is directed to a communication device that includes a microphone configured to detect an acoustic signal from an acoustic environment, and a processor, configured to detect an acoustical dampening between the acoustic environment and the microphone, based on a change in a characteristic of the acoustic signal and, responsive to the acoustical dampening, apply a compensation filter to the acoustic signal to form a compensated acoustic signal that is reproduced. Other embodiments are disclosed.

Acoustic device and methods

A method of incorporating environmental acoustic sources into a virtual environment by measuring real environment acoustic sources and locations and incorporating them into a virtual environment with virtual acoustic sources.

Location based audio signal message processing

At least one exemplary embodiment is directed to a method of determining hearing loss using audio cues whose spectrum is orthogonal to each other to identify a wearer's hearing loss, and using the information to adjust audio to normal listening levels.

Hearing sensitivity acquisition methods and devices

A device to test the seal quality of an earpiece. Audio processing circuitry produces an audio signal for driving a speaker. Output from the microphone while the speaker is being driven by the audio signal is used to determine the seal. The device or method further includes control circuitry to evaluate a seal quality of the device. Other embodiments are disclosed.

Acoustic sealing analysis system

An earpiece () and acoustic management module () for in-ear canal echo suppression control suitable is provided. The earpiece can include an Ambient Sound Microphone () to capture ambient sound, an Ear Canal Receiver () to deliver audio content to an ear canal, an Ear Canal Microphone () configured to capture internal sound, and a processor () to generate a voice activity level () and suppress an echo of spoken voice in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal () that is delivered to the ear canal ().

Method and device for in-ear echo suppression

At least one exemplary embodiment is directed to a method of testing the earphone for proper sealing then generating a self-administered hearing test.

Method to acquire preferred dynamic range function for speech enhancement

Acoustic dampening compensation system

A method and device for automatically increasing the spectral bandwidth of an audio signal including generating a 'mapping'(or 'prediction') matrix based on the analysis of a reference wideband signal and a reference narrowband signal, the mapping matrix being a transformation matrix to predict high frequency energy from a low frequency energy envelope, generating an energy envelope analysis of an input narrowband audio signal, generating a resynthesized noise signal by processing a random noise signal with the mapping matrix and the envelope analysis, high-pass filtering the resynthesized noise signal, and summing the high-pass filtered resynthesized noise signal with the original an input narrowband audio signal. Other embodiments are disclosed.

Method and device for spectral expansion for an audio signal

Earpieces and methods for acute sound detection and reproduction are provided. A method can include measuring an external ambient sound level (xASL), monitoring a change in the xASL for detecting an acute sound, estimating a proximity of the acute sound, and upon detecting the acute sound and its proximity, reproducing the acute sound within an ear canal, where the ear canal is at least partially occluded by an earpiece. Other embodiments are disclosed.
