  • Publication number: 20110029288
    Abstract: Noise discrimination in signals from a plurality of sensors is conducted by enhancing the phase difference in the signals such that off-axis pick-up is suppressed while on-axis pick-up is enhanced. Alternatively, attenuation/expansion are applied to the signals in a phase difference dependent manner, consistent with suppression of off-axis pick-up and on-axis enhancement. Nulls between sensitivity lobes are widened, effectively narrowing the sensitivity lobes and improving directionality and noise discrimination.

  • Publication number: 20100061583
    Abstract: A wired or wireless earset assembly comprises an earset housing having a curved portion configured to fit to the top of an ear, a speaker driver contained in a speaker housing, a flexible tube having a first extension so as to be coupled with at least a part of the curved portion of the earset housing and a second extension coupled with the speaker housing, a rotatable cap containing a bud coupled with the speaker driver, a sound delivery port in the bud, a circuitry for processing an input signal in the case, and a wire in the flexible tube connecting the circuitry and the speaker driver. The structure of the assembly allows a user to wear it with great comfort and high quality acoustic performance for an extended period, enables the assembly to fit to both right and left ears by a simple rotation of the cap, and increases ease of manufacturability.

  • Publication number: 20090136057
    Abstract: In one embodiment, a method for matching first and second signals includes transforming, over a selected frequency band, the first and second signals into the frequency domain such that frequency components of the first and second signals are assigned to associated frequency bins, generating a scaling ratio associated with each frequency bin, and for at least one of the two signals, or at least a third signal derived from one of the two signals, scaling frequency components associated with each frequency bin by the scaling ratio associated with that frequency bin. The generating comprises determining, during a non-startup period, a signal ratio of the first and second signals for each frequency bin, determining the usability of each signal ratio, and designating a signal ratio as a scaling ratio if it is determined to be usable.

  • Patent number: 7522743
    Abstract: A high comfort sound delivery system (10) for use with a personal communications device such as a telephone. The high comfort sound delivery system (10) has a behind-the-ear member (12) for holding the device on or near an ear of the user, and a sound horn (14) to be positioned at or near the ear canal of the user. Sound is produced by a speaker (26) in a speaker enclosure portion (15) of the behind-the-ear piece (12) and is delivered to the sound horn (14) through a generally flexible connecting member (16). Rotational adjustment is provide to rotating the connecting member (16) in relation to a speaker tube connection projection (20) and/or a sound horn tube connection projection (46). A length adjustment is provided by moving an elongated portion (66) of the connecting member (16) of the sound horn tube connection projection (46). Alternate sound horn bodies (42a, 42b, 42c, 42d, 42e, 42f) provide addition rotational adjustment points.

  • Publication number: 20080152167
    Abstract: Near-field sensing of wave signals, for example for application in headsets and earsets, is accomplished by placing two or more spaced-apart microphones along a line generally between the headset and the user's mouth. The signals produced at the output of the microphones will disagree in amplitude and time delay for the desired signal—the wearer's voice—but will disagree in a different manner for the ambient noises. Utilization of this difference enables recognizing, and subsequently ignoring, the noise portion of the signals and passing a clean voice signal. A first approach involves a complex vector difference equation applied in the frequency domain that creates a noise-reduced result. A second approach creates an attenuation value that is proportional to the complex vector difference, and applies this attenuation value to the original signal in order to effect a reduction of the noise. The two approaches can be applied separately or combined.

  • Patent number: 7206421
    Abstract: The present invention, generally speaking, picks up a voice or other sound signal of interest and creates a higher voice-to-background-noise ratio in the output signal so that a user enjoys higher intelligibility of the voice signal. In particular, beamforming techniques are used to provide optimized signals to the user for further increasing the understanding of speech in noisy environments and for reducing user listening fatigue. In one embodiment, signal-to-noise performance is optimized even if some of the binaural cues are sacrificed. In this embodiment, an optimum mix ratio or weighting ratio is determined in accordance with the ratio of noise power in the binaural signals. Enhancement circuitry is easily implemented in either analog or digital form and is compatible with existing sound processing methods, e.g., noise reduction algorithms and compression/expansion processing. The sound enhancement approach is compatible with, and additive to, any microphone directionality or noise canceling technology.

  • Patent number: 7027603
    Abstract: A highly discreet and accurate voice pickup device includes a standard miniature pressure gradient type microphone element provided and mounted very close to the side of the user's head, preferably near the user's ear. The microphone element is oriented so that its direction of maximum sensitivity is parallel to the side of the user's head, and points toward the user's mouth so that it will pick up the user's speech sounds as the sounds diffract and travel along the side of the user's face and head, to the microphone element. The microphone element can be configured with low pass networks at front and rear ports of the microphone element, which cooperate with air volumes within the microphone to provide additional directional properties that advantageously vary with frequency and further enhance the noise-rejection capability of the microphone element.
