摘要： In accordance with an implementation of the disclosure, systems and methods are provided for providing an estimate for noise in a speech signal. An instantaneous power value is received that corresponds to a frequency index of a portion of the speech signal. A first weighted power value is updated based on the instantaneous power value and a first weighting parameter. A second weighted power value is updated based on the first weighed power value and a second weighting parameter. An estimate of the noise is computed from the instantaneous power value and the second weighted power value.

摘要： The invention includes a method, apparatus, and computer program to selectively suppress wind noise while preserving narrow-band signals in acoustic data. Sound from one or several microphones is digitized into binary data. A time-frequency transform is applied to the data to produce a series of spectra. The spectra are analyzed to detect the presence of wind noise and narrow band signals. Wind noise is selectively suppressed while preserving the narrow band signals. The narrow band signal is interpolated through the times and frequencies when it is masked by the wind noise. A time series is then synthesized from the signal spectral estimate that can be listened to. This invention overcomes prior art limitations that require more than one microphone and an independent measurement of wind speed. Its application results in good-quality speech from data severely degraded by wind noise.

摘要： A capacitive vacuum sensor includes an elastic diaphragm electrode and a rigid fixed electrode opposite the elastic diaphragm electrode. An internal space is defined between the elastic diaphragm electrode and the rigid fixed electrode. The elastic diaphragm electrode deflects elastically in response to any change in the pressure of a gas applied on the elastic diaphragm electrode, and the capacitive vacuum sensor is responsive to any change in the capacitance between the elastic diaphragm electrode and the rigid fixed electrode that may occur in accordance with the deflection of the elastic diaphragm electrode so that it can measure the pressure of the gas. The vacuum sensor can include an anticorrosive diaphragm electrode that can resist the corrosive action of the reactive gas when it is exposed to such gas, and can be fabricated by the micromachining technology.

摘要： Vacuum pressure of a gas in a compartment (1) is measured. The vacuum pressure is established by a pump arrangement (3,5) with a pulsating pumping effect (g(t)). The shape of the resulting pulsation of the pressure (p(t)) in compartment (1) is exploited (15) as an indication of the operation status of the pump arrangement (3,5).

摘要： A unique, fully integrated, fully programmable, and highly flexible sound distribution system and methodology for providing masking sound, background music, and paging capabilities in up to eight zones of a building or space is provided. The methodology embodied in the system includes internal masking sounds that are uniquely pre-filtered to provide efficient and effective masking of distracting sounds within selectable zones of the space with a minimum masking sound dB sound level and with a pleasant sounding and non-annoying masking sound. The system also incorporates the capacity to be controlled from a remote or local telephone to adjust the volume level in any zone serviced by the system by issuing appropriate DTMF codes from the telephone's keypad. Unique bi-tone diagnostic functions are provided for assuring that the entire system is correctly wired and installed and for troubleshooting operational anomalies. ⅓ octave equalization is provided to compensate for known frequency response characteristics of the flat panel radiators of the system and to compensate for varying room acoustics to provide a low special variation of sound among the various zones of the space. The result is a high quality high fidelity sound that is consistent from zone to zone.

摘要： A device for determining the quality of an output signal to be generated by a signal processing circuit with respect to a reference signal. The device is provided with a first series circuit for receiving the output signal and a second series circuit for receiving the reference signal. The device generates an objective quality signal through a combining circuit which is coupled to the two series circuits. Poor correlation between the objective quality and subjective quality signals, the latter which will be assessed by human observers, can be considerably improved by a differential arrangement present in the combining circuit. This arrangement determines a difference between the two series circuit signals and reduces this difference by a certain value, preferably one that is a function of a series circuit signal. Poor correlation can be improved further by disposing a scaling circuit, between the two series circuits, for scaling at least one series circuit signal. Furthermore, the quality signal can also be scaled as a function of the scaling circuit.
