The invention relates to a hearing aid a cochlear implant comprising a) at least one input transducer for capturing incoming sound and for generating electric audio signals which represent frequency bands of the incoming sound, b) a sound processor which is configured to analyze and to process the electric audio signals, c) a transmitter that sends the processed electric audio signals, d) a receiver/stimulator, which receives the processed electric audio signals from the transmitter and converts the processed electric audio signals into electric pulses, e) an electrode array embedded in the cochlear comprising a number of electrodes for stimulating the cochlear nerve with said electric pulses, and f) a control unit configured to control the distribution of said electric pulses to the number of said electrodes. The control unit is configured to distribute said electric pulses to the number of said electrodes by applying one out of a plurality of different coding schemes, and wherein the applied coding scheme is selected according to characteristics of the incoming sound.

A volume-based earbud switching method is applied to a wearable device. The wearable device includes: a first earbud and a second earbud; The method includes: obtaining a first volume of the first earbud and a second volume of a second earbud; calculating a first power consumption speed of the first earbud and a second power consumption speed of the second earbud; and determining an earbud switching policy between the first earbud and the second earbud according to the first and the second power consumption speeds; and sending an earbud switching command to an electronic device connected with the wearable device according to the earbud switching policy, wherein the earbud switching command is used to direct the electronic device to execute switching between the first earbud and the second earbud.

Wireless headphones with battery life effectively extended includes first and second headphones. The first and second headphones each with respective low battery levels remaining or very different battery levels remaining receive audio signals from an electronic device and output the sound of the audio signal after adjustments are applied to volume level and to sound quality on one side or on both sides, to reduce the consumption of battery level. Each of the first and second headphones carries a processor for intercommunication in addition to communication with the electronic device performing playback.

An apparatus and method are provided to determine a parameter using an auditory model of a hearing loss patient. The parameter determination apparatus determines a similarity between a neurogram of a normal subject and a neurogram of a hearing loss patient, and determines an optimal frequency band for the hearing loss patient based on the similarity.

An audio signal is transmitted from a transmitter to a receiver in a hearing device, particularly a hearing aid. A communication facility configured for transmitting and/or receiving the audio signal. A hearing device system has two hearing devices configured to transmit audio signals between the two hearing devices by way of their communication facilities in accordance with the method.

Systems, methods, and non-transitory computer-readable storage media for performing a role swapping operation between a pair of non-tethered wireless ear buds after detecting a triggering event. Further, state information can be coordinated between devices, including in connection with performing a role swap between buds in a pair of wireless, untethered ear buds, where one wireless ear bud is in a primary role and is responsible for a connection with a companion device, and another wireless ear bud in the pair is in a secondary role.

A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.

A method transmits an audio signal from a transmitter to a receiver and a hearing device, particularly a hearing aid, contains a communication facility which is provided and configured for transmitting and/or receiving an audio signal according to the method. A hearing device system has two hearing devices and is provided and configured to transmit audio signals between the two hearing devices by their communication facilities according to the method.

Provided is a digital acoustic system comprising: a ΔΣ modulator that modulates a digital input signal and outputs a digital signal; a post-filter that is connected to the ΔΣ modulator and which performs mismatch shaping to convert the digital signal; a parallel-serial converter that converts the digital signal converted by the post-filter into a digital signal which is serially transmitted; a serial-parallel converter that restores the digital signal converted by the parallel-serial converter; and a drive circuit which receives the digital signal restored by the serial-parallel converter, and drives drive elements to convert the signal into an analog audio signal.

A voice input/output device is connected to a smart device having a voice signal input/output function is provided. A digital voice signal output by the smart device is output to an output unit, (e.g., ear receiver or a speaker), in the form of a voice, and a voice signal transmitted by the smart device is extracted and input to the smart device as a digital voice signal to generate a sound by the smart device itself in addition to an externally generated sound that is input again with improved quality. Accordingly, a voice signal output by the smart device is extracted using a earphone type device having microphone mounted thereon and the voice signal is input to the smart device again.
