The first output signal and the second output signal correspond to an audio zoomed signal.

In-ear sound pressure level, SPL, is determined that is caused by output audio being converted into sound by a headset worn by a user. The in-ear SPL is converted into a sound sample having units that are suitable for evaluating sound noise exposure. These operations are repeated to produce a sequence of sound samples during playback. This sequence of sound samples is then written to a secure database. Access to the database is authorized by the user. Other aspects are also described and claimed.

In one aspect, a first device includes a processor and storage accessible to the processor. The storage bears instructions executable by the processor to receive information pertaining to a location of a user and, based at least in part on the information, determine an apparatus to actuate from among plural apparatuses to participate in communication concerning audio data. The instructions are also executable to, based at least in part on the determination, participate in communication with the apparatus concerning audio data.

A device or a method using the device includes a sealing section configured to seal a user's orifice, where the sealing section is configured to produce an acoustic seal between a first side of the sealing section and a second side of the sealing section and audio processing circuitry to produce an audio signal for driving a speaker in the device and to measure sound level using output from the microphone in the device while the speaker is being driven by the audio signal. The device or method further includes control circuitry to evaluate a seal quality of the device. Other embodiments are disclosed.

Systems and methods for recording and playback of multi-dimensional sound are described herein. The systems and methods may include positioning a plurality of multi-dimensional sound recording devices in a location and positioning a plurality of multi-dimensional sound recording sensors within the location. Then, acoustical footprint data can be generated. Next, recording positional data within the location utilizing the plurality of multi-dimensional sound recording devices may occur. The systems and methods may continue to generate spatial data utilizing the recorded positional data and store the generated acoustical footprint data and spatial data. An audio mix-down utilizing the stored acoustical footprint and spatial data is generated. Finally, a consumer-device audio track mix based on the audio mix-down can be generated. Further embodiments may also replace audio tracks to mimic the original recording conditions in other languages and environment. Playback may occur on a device that generates a profile of the playback area.

An assistant guiding system includes a plurality of radio frequency identification (RFID) tags, a server, and an earphone assembly. The plurality of RFID tags is located at a predetermined area, and each RFID tag pre-stores an identification number of the predetermined area. The server stores scenic spot introduction information of the predetermined area. The earphone assembly communicates with a portable electronic device of tourists, and the portable electronic device downloads the scenic spot introduction information from the server. The earphone assembly includes a reading module and a transmission module. The reading module reads the identification number from the RFID tag. The transmission module sends the identification number to the portable electronic device. The scenic spot introduction information corresponding to the identification number of the predetermined area is played or displayed on the portable electronic device.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing binaural navigational cures. In one aspect, a method includes presenting audio media in a non-directional playback state that presents the audible media in an original format, iteratively determining a navigational heading relative to a current navigational course, the navigational heading indicative of a direction to face to proceed along a navigational route, and for each iteration, determining whether a change is required to the current navigational course based on the navigational heading. For each determination that a change is not required to the current navigational course, presenting the audio media in the non-directional playback state, and for each determination that a change is required to the current navigational course, changing the non-directional playback state to a directional playback state that presents the audible media in a modified format that is directional from the navigational heading.

A system for presenting audio content to a user. The system comprises one or more microphones coupled to a frame of a headset. The one or more microphones capture sound from a local area. The system further comprises an audio controller integrated into the headset and communicatively coupled to an in-ear device worn by a user. The audio controller identifies one or more sound sources in the local area based on the captured sound. The audio controller further determines a target sound source of the one or more sound sources and determines one or more filters to apply to a sound signal associated with the target sound source in the captured sound. The audio controller further generates an augmented sound signal by applying the one or more filters to the sound signal and provides the augmented sound signal to the in-ear device for presentation to a user.

A hearing aid includes an input unit, an output unit, a signal processing unit connected to said input unit and output unit, where the input unit, the signal processing unit and the output unit are forming part of a forward path of the hearing aid, where the signal processing unit is configured to apply a forward gain to the at least one electric input signal or a signal originating therefrom. The hearing aid further includes a feedback control unit configured to reduce a risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit of said hearing aid, where the hearing aid is configured to receive motion data characterising movement and/or acceleration and/or orientation and/or position of the hearing aid to control processing.
