摘要： An appropriate binary sequence is used to create an acoustical treatment surface having desired parts with reflective properties and desired parts having absorptive properties resulting in the net effect of partially diffusive, partially absorptive properties. A genetic algorithm is designed to search for optimal 1D and 2D configurations for the acoustical treatments. A genetic algorithm essentially mimics the process of evolution that occurs in biology and is a known mathematical technique. During the course of genetic optimization, the fitness of individual sequences for the desired purposes is calculated. A useful fitness function includes terms that optimize the desired percentage of reflectivity and absorptivity. Through use of genetically optimized binary sequences, a curved surface may be constructed and optimized to find the best shape to achieve even scattering. The curved surface produces a dramatic improvement in effectiveness of diffusion.

摘要： An apparatus for the redistribution of acoustic energy is provided which comprises a lens having a reflective surface defined by the surface of revolution R1 of an elliptical arc A1 rotated about a line L through an angle .alpha.1 and the surface of revolution R2 of an elliptical arc A2 rotated about the line L through an angle .alpha.2. Each elliptical arc A1 and A2 constitutes a portion of an ellipse E1 or E2 having a focal point located at a point F1 on line L, and shares an end point P which lies on the reflective surface and the line L. The angle .alpha.1 is chosen such that the surface of revolution R1 is convex with respect to an adjoining surface S1 and the angle .alpha.2 is chosen such that the surface of revolution R2 is concave with respect to the adjoining surface S1.

摘要： Apparatus for supporting an acoustical diffuser panel within a structure. A preferred apparatus includes a rigid support member fabricated from an acoustically absorptive material. The support member has a bottom and upstanding side walls that define a well that is sized to receive a diffuser panel therein. The diffuser panel may comprise a plurality of column members that are integrally formed with a planar bottom surface and extend therefrom. At least one column member is longer than at least one other column member. Another diffuser panel that can be successfully used has a series of elongated columns that extend for the width or length of the panel. At least one column member extends a distance above the bottom of the support member that differs from the distance that another column extends above the support member when the panel is received therein. A method for installing at least one acoustical diffuser assembly into a wall structure and an acoustical wall structure are also disclosed.

摘要： A two-dimensional binary amplitude diffusor (BAD) offering both absorption and modest diffusion is disclosed. The invention consists of a flat-faced panel with a series of alternating reflective and absorptive regions or patches defined by a binary sequence consisting of zeros and ones with a flat power spectrum, such as the Maximum Length Sequence (MLS) based upon shift register theory. Combining regions of absorption and reflection in the manner described herein results in an effective combination of absorption and diffusion.

摘要： An acoustic resonance chamber in an underwater pinger is designed to enhance the acoustic emission from the pinger. An electro-acoustic transducer of the pinger is positioned away from a reflective surface of the pinger housing by a distance chosen in proportion to the wavelength of the fundamental frequency of the acoustic emission. This creates a resonant condition at the transducer, maximizing the acoustic output. This design also causes a maximum transfer of the acoustic wave through the pinger housing and into the surrounding water.

摘要： A two-dimensional sound diffusor is composed of a plurality of wells defined by a matrix of projecting elements. The wells, which have different depths and widths, are arranged in a repeating pattern. The boundaries of the wells and of the repeating pattern are defined by projections arranged on a base. The ends of the projections extend away from the base, terminating in an inclined face which is inclined relative to the base by an angle of 10.degree.. The incline may be rotated from one projection to the next, on a plane parallel to the base of the unit by 90.degree. or 180.degree.. This arrangement produces two dimensional sound diffusion.

摘要： A device is disclosed which allows an object to be tuned to an incoming sound wave magnitude and wavelength, such that the sound wave will alternatively be passed therethrough without detectable reflection or be completely reflected. The apparatus is intended to be mounted within a hollow object and adjust the perceived distance between the exterior walls of that object to mimic a single thick wall. A signal processing means is supplied which detects the sound wave magnitude and wavelength impinging on the wall facing the sound wave source. The wavelength is passed to the signal processing means, which transmits a complimentary signal to the second wall of the hollow object. The complimentary signal allows the hollow object to resonate as a whole as if it were a solid of a thickness much different from its actual thickness, allowing the sound wave to pass undisturbed therethrough or be reflected therefrom.
