摘要： The invention relates to a method and an equipment for attenuating sound in a duct. Sound propagating in a duct is detected by means of a detector (2) and attenuated by using two successive monopole elements (3, 4) in such a way that both elements function as a dipole approximation and the elements are also used to approximatively produce the monopole radiation needed. A dipole control signal is fed to both elements (3, 4) at a phase shift which is 180° between the two elements. In addition, a monopole control signal is fed to the same elements (3, 4), only this time cophasally. Total volume velocities produced by the two elements (3, 4) are combinations of the portions obtained from the monopole and dipole sources.

摘要： An acoustical transformer or "phasing plug" for coupling sound from a speaker diaphragm to the throat of a horn. The phasing plug of the invention is in the general shape of a dome on one side and a truncated cone on the other, and has evenly spaced radial slots or channels formed therein, these slots forming air passageways for propagation of the soundwaves. The walls of the slots are tapered exponentially from their inlet ends at the speaker diaphragm towards a flat plane outlet at the throat of the horn, to provide an optimum impedance match between the output of the diaphragm and the input of the horn; the sound channels formed by the slots exponentially increasing in area between their inlets and outlets. Transformation from a spherical wave front at the input to a plane wave front at the outlet is assured by the shaping of the channels to make the distances between corresponding points at the channel inlets and outlets equal to each other.

摘要： There are provided a method and an apparatus for reducing random, continuous, non-stationary noise in audio signals, the noisy audio signal being filtered by means of a predetermined filter function. The filter function is determined dynamically having regard to the current properties of the noisy audio signal and/or its constituent parts, and the filter function is also limited dynamically having regard to the current properties of the noise component contained in the noisy audio signal.

摘要： Composite acoustic imaging and image deflection system adapted for use in a fluid medium and utilized for forming acoustic images with incident acoustic waves and at the same time deflecting or sweeping the image so formed over an image field so that the entire compressional acoustic image field of interest is swept by a line (in practice a linear array of transducers for converting the incident acoustic image compressional field to an equivalent electrical signal) contained in a plane which includes the axis of the incident acoustic image field. The imaging and image deflection system includes a composite lens assembly which incorporates two or more lens elements with a fluid filler medium contained therebetween to provide the focusing action and a pair of refracting prisms disposed between the lens elements (in the fluid medium) and mounted for counterrotation relative to each other, each in its own plane, to provide image deflection. In other embodiments the lens elements and prisms are combined by providing proper lens contours for prismatic lenses, e.g., by providing focusing lens contours on one side of each element and the slanting plane surface of a prism on the other face and providing means to counterrotate the lens elements so that the combined lens and prism elements perform both the focusing and image deflection functions. In order to reduce the radius of curvature of the lens elements and/or the slope of the sides of prisms to such an extent that mode conversion at liquid/solid interfaces is substantially eliminated while providing the required imaging and deflection (refraction), the materials of the lens, prisms and entrained liquid media are so selected that the velocity of propagation of acoustic waves in the medium at least on one side of the lens assembly is intermediate the velocity of propagation in the filler medium and the medium of the lenses and prisms.

摘要： Disclosed is an enclosure for ultrasonic transducers that can either project a narrow beam of energy or receive energy within a narrow cone of angles and also protect the transducer from damage. The enclosure defines an opening that is covered with a screen mesh that permits ingress and egress of wave energy. Within the enclosure the wave energy is subjected to a plurality of reflections from conically shaped reflective surfaces that provide optical shielding for the transducer, yet maintain the planar wave characteristics. An embodiment is disclosed that passes the wave energy through a honeycomb structure to further enhance directional properties. The subject enclosure can be used as a transmitter of wave energy or a directional receiver of wave energy.
