摘要： A method and apparatus (10) for objectively assessing acoustical performance of an in-ear device (12) having a passageway (20) extending there through use a dual microphone probe (26) that removably engages the passageway (20). The acoustical performance of the in-ear device (12) is performed with the in-ear device (12) inserted into the ear canal (14) of the user and a reference sound source (24). A clip (36) holding the probe (26) in an acoustic near field of the sound source (24) permits real time calibration thereof. The method and apparatus (10) allow on-site and in-situ measurement of a predicted personal attenuation rating (P-PAR) of the device, a subject-fit re-insertion test, an acoustic seal test, a rating test, a stability and reliability test, as well as a protection test of the device (12) with an assessment of a filtered predicted exposure level (F-PEL) at the ear for a specific noise exposure level. The apparatus (10) may be simply housed along with the sound source (24) for in-field evaluation tests.

摘要： A method and a system for measuring the energy of a signal is based on the use of a time-frequency distribution using as kernel a bi-dimensional filter having compact support properties. The two-dimentional filter is applied to the two-dimensional correlation function of the signal to be analyzed. The system includes an acquisition unit for providing samples (s(n)) of the signal, a Hilbert transformer (26, 104) for producing analytical signals from those samples, and a local correlator (28) for computing the convolutions of a kernel derived from a Gaussian kernel and having compact support properties and instantaneous autocorrelation functions so as to yield generalized instantaneous autocorrelation functions, and a Fourier transformer (30, 128) for determining information related to the energy of the signal from the derived generalized instantaneous autocorrelation functions. The method and system allows a better reduction of false energy observances (interference) while providing good resolution in time and in frequency.

摘要： A system, device and method to condition a wide-band calibration stimulus such as a chirp or logarithmic chirp with the purpose of reducing the dynamic range necessary for an acquisition system of an audio wearable device. The dynamic range of the stimulus is compressed using a temporal envelope and digital filters to prevent the high magnitude of the resonance peaks from clipping or saturating the response signal. Such pre-conditioning method for the calibration of the audio wearable device may allow the use of a low -depth or low-resolution acquisition system to perform the measurements.

摘要： 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.

摘要： A method for determining an ear canal size of a user is provided. The method comprises measuring a cross-section perimeter of the little finger of the user at a predetermined distance from base of the little finger of the user, the predetermined distance being between 2/3 and 9/10 of the length of the little finger. The measured cross-section perimeter of the little finger determines the cross-section perimeter of between the opening the ear canal and 1/4 to 1/2 of the length of the ear canal. An earplug finger-gage device comprises plurality of side cavities, each cavity has the same predetermined depth and a first opening having a diameter differing from one another and being adapted to receive a finger. The size of a cross-section of the finger is selected when pressure against the cavity is neither too tight nor too wide to be felt against the cavities.

摘要： A system and a method to determine heart and/or breathing rates. The system comprises a shell configured to occlude an ear canal, an in-ear microphone located inside the shell to capture an audio signal inside the ear canal, and a processor operatively connected to the in-ear microphone, the processor being configured to analyse the audio signal in order to determine at least one of a heart beat and/or a respiration rate measurement or attribute, even when the wearer of the system is immersed in high level of environmental noise. The system and method also comprise the use of an adaptive digital filter to remove the residual environmental noise from the audio signal captured by the in-ear microphone. The system and method also comprise the use of a predetermined audio signal association to identify attributes of the captured audio signal inside the ear canal.
