An analysis system has at least one monitoring assembly that includes at least one microphone to monitor an acoustic field proximate the monitoring assembly. The at least one microphone produces at least one microphone signal responsive to the acoustic field. The analysis system further includes a data storage device configured to buffer the at least one microphone signal and an audio analysis system configured to analyze a content of the data storage device where the audio analysis system is configured to analyze the content of the buffer to process at least a sound into a response or action.

An apparatus for fitting an earphone device in an ear canal using an anatomically shaped, compressible cushion member with a through channel and a spacer member extending from its side wall, but not connecting to its other side wall, thus providing sufficient acoustic signal transmission to the ear canal in all circumstances by ensuring a 5 minimum clearance C between the opposing side walls of the channel in both a non-compressed state and a compressed state of the cushion member, while also allowing for a flexible and comfortable design.

An earphone according to the present disclosure includes: a speaker unit that generates a sound wave; a case having one end and the other end opposite to the one end and housing the speaker unit; and a sound conduit connected to the one end side of the case and provided with a sound hole that emits the sound wave generated from the speaker unit, in which an internal space connected to the sound hole is provided between the speaker unit and the sound conduit in the case, and the case is provided with a plurality of vent holes that communicate the internal space with an external space that is outside the case.

A device, system and related methods to provide assessment and treatment of amblyaudia through standardized methods that do not require advanced training or a booth with loudspeakers for the operator to administer. The ARIA stimuli protocols for both assessment and treatment, encoded in or to be used by a software program or application, are transferred to a stand-alone set of specialized noise-cancelling headphones attached or connected to, wired or wirelessly, a software platform on an electronic computing device. or integrated with the headphones. The program administers assessment tests to individuals through the noise-cancelling earphones. The device enables someone with minimal instructions to administer automatically or semi-automatically both assessment and treatment protocols, generate results, make interpretations, store data, and produce reports. The device or system may be loaded with standard protocols for English-speaking individuals, as well as dichotic speech material in any language.

An in-ear hearing protection device is provided. The in-ear hearing protection device includes a microphone (410) configured to receive an ambient sound. The in-ear hearing protection device also includes a processor (420) configured to perform an attenuation function on the received ambient sound to provide an attenuated sound. The in-ear hearing protection device also includes a speaker (440) configured to broadcast the attenuated sound. The in-ear hearing protection device also includes a communication module (430) configured to receive a second attenuation function detail from a second in-ear protection device. The processor is configured to calculate a first attenuation function detail and compare the first and second attenuation function details. The performed attenuation function is based on one of the first and second attenuation function details.

To accurately achieve synchronization between a master and a slave that perform wireless communication.

A synchronization device that synchronizes time-series data between a master and a slave by wireless communication, the master including a packet transmission unit that transmits a plurality of packets at a predetermined interval, and the slave including a synchronization unit that synchronizes time-series data transmitted by the master and time-series data received by the slave on the basis of the interval between the plurality of packets.

A system and method for providing sensory relief from distractibility, inattention, anxiety, fatigue, and/or sensory issues to a user in need. The user can be autistic/neurodiverse, or neurotypical. The system can be configured to connect to a datastore storing one or more sensory thresholds specific to a user of a wearable device of the system, the sensory thresholds selected from auditory, visual or physiological sensory thresholds; record, using one or more sensors of the wearable device, a sensory input stimulus to the user; compare the sensory input stimulus with the sensory thresholds to determine an intervention to be provided to the user, the intervention configured to provide the user relief from distractibility, inattention, anxiety, fatigue, or sensory issues; and provide the intervention to the user, the intervention comprising filtering, in real-time, an audio signal presented to the user or an optical signal presented to the user.

Examples of an aiding device for singers are described. The aiding device comprises a body that has a periphery edge, a top wall and a smooth inner wall. The top wall curves away from the periphery edge thus forming a cup-like cavity which is shaped to define a first chamber and a second chamber that are interconnected together. The first chamber is shaped and sized to fit over an earlobe of a singer while the second chamber has a distal end that is designed and configured to be positioned in proximity to a user's mouth. When in use the first chamber encloses one of user's ears and the distal end of the second chamber is positioned in proximity to user's mouth with the periphery edge pressed against user's face such that a sound produced by the user is captured and travels into the second and first chamber and is reflected back from the smooth inner wall producing echo within the cavity. Thus, the unfiltered sound coming out from the singer's mouth is provided to one of the singer's ear in real time and hear the original sound or key in the other ear so that the singer can match his/her pitch to the original sound.

The present invention discloses an indoor Electronic Traveling Aid (ETA) system for blind and visually impaired (BVI) people. The system comprises a headband, intuitive tactile display with myographic (EMG) feedback, controller, and server-based methods corresponding to three operation modalities. In 1.sup.st modality, sighted users mark routes, map navigational directions, and create semantic comments for BVIs. This information of routes is continuously collected and estimated in ETA servers. In the 2.sup.nd modality, BVIs choose the routes from servers, thereby, are supplied with real-time navigational guidance. Also, an EMG interface is used, where the user's facial muscles are enabled is to send commands to the ETA system. In the 3.sup.rd modality, BVIs receive real-time audio guidance in complex or unforeseen situations: ETA provides a crowd-assisted interface and real-time sensory (e.g., video) data, where crowd-assistants analyze the situation and help the BVI to navigate.
