Abstract: An inflatable in-ear device includes a core member with a platform provided with a sealing assembly in the form of a locating recess for the registration of a retention ring formed around a defining opening of a sheath arranged in close circumjacent manner around the platform attached to the core member, an abutment surface being formed on a capping for the platform and the core member whereby in use positive location of the retention ring within the recess is achieved by the closure of the recess by the abutment surface. A space is defined between the sheath and the core member for the injection of a settable material used for the inflation of the sheath once the device is emplaced within the ear canal of the ear.

Abstract: A device and a method for detecting voice of a user of an intra-aural device. The intra-aural device has an in-ear microphone adapted to be in fluid communication with an outer-ear ear canal of the user occluded from an environment outside the ear. A signal provided by the in-ear microphone is obtained to determine an acquired voice indicator signal, and a voice produced by the user is detecting by comparing the acquired voice indicator signal with a corresponding threshold value, upon the acquired voice indicator signal being larger than the corresponding threshold value. Although the method also reduces any voice interference coming from a non-user, the results are improved when the non-user voice is captured from an outer-ear microphone of the intra-aural device.

Abstract: A method, and device, for enhancing speech generated from bone and tissue conduction of a user of an In-ear device in a noisy environment, the Intra-aural device having an in-ear microphone adapted to be in fluid communication with the ear canal of the user and an outer-ear microphone adapted to be in fluid communication with the environment outside the ear. The method comprises applying an adaptive filter on the in-ear microphone signal, using the outer-ear microphone signal as a reference for the ambient noise and interrupting the application of the adaptive filter to the In-ear microphone signal upon detecting speech by the user.

Abstract: An earpiece adapts to the acoustics characteristics and needs of its user to provide a perceptually transparent hearing protection, apart from uniform loudness reduction. An occlusion effect (OE) active noise control (ANC) system reduces the augmented perception of one's own voice while occluded. This occlusion effect active control adapts to the specific acoustic characteristics of the user to provided better control of the details occlusion effect reduction, and enhanced performances relative to fixed or one-size-fits-all solutions. An isolation effect (IE) filtering algorithm adapts itself to the user's acoustic characteristics to provide a uniform attenuation either in dB or in phons. Additionally, the device may be used as an in-ear monitor that also adapts to its user characteristics to provide in-ear quality sound.

Abstract: A system and method for training a classification module of nonverbal audio events and a classification module for use in a variety of nonverbal audio event monitoring, detection and command systems. The method comprises capturing an in-ear audio signal from an occluded ear and defining at least one nonverbal audio event associated to the captured in-ear audio signal. Then sampling and extracting features from the in-ear audio signal. Once the extracted features are validated, associating the extracted features to the at least one nonverbal audio event and updating the classification module with the association. The nonverbal audio event comprises one or a combination of user-induced or externally-induced nonverbal audio events such as teeth clicking, tongue clicking, blinking, eye closing, teeth grinding, throat clearing, saliva noise, swallowing, coughing, talking, yawning with inspiration, yawning with expiration, respiration, heartbeat and head or body movement, wind, earpiece insertion or removal, degrading parts, etc.

Abstract: A system to detect a man down situation using intra-aural inertial measurement units is disclosed. The system comprises an earpiece having an inertial measurement unit (IMU) adapted to capture acceleration and rotation speed of the earpiece. The method comprises a training phase to characterize statistical distribution models of extreme values of feature signals, segmented by their respective optimally-sized time windows and to merge the detection probability provided by the statistical model of the feature signals. The method further comprises a prediction phase. The prediction phase comprises applying the detection strategy on independent data, based on the critical states obtained from the characterization. The data from the said inertial measurement of the MEMS are used for the detection of full (F), immobility (I) and down on the ground (D) states.

Abstract: A device and method for the continuous monitoring of otoacoustic emissions (OAE) levels on an individual worker uses as a pair of earpieces each featuring an external microphone, an internal microphone and a pair of miniature receivers. An adaptive filtering noise rejection processing of the measured distortion product OAE (DPOAE) is used to further improve the Signal-to-Noise ratio in frequencies where passive isolation remains insufficient. The adaptive filtering noise rejection technique relies on a Normalized Least-Mean-Square (NLMS) algorithm that uses the ipsilateral external microphone and the contralateral internal microphone to reject the noise from the measured DPOAE signals for each in-ear OAE probe. A DPOAE signal extraction algorithm provides for an increase in results reliability on a greater dynamic range in DPOAE magnitudes than known methods of DPOAE signal extraction. The device and method is suitable for the continuous monitoring of workers' hearing capabilities in industrial noises up to 75 dB(A).
