American Technology's HyperSonic Sound Adds Super Bass Directivity Not Previously Possible; Tests on Directivity Illustrate Important Benefits.SAN DIEGO--(BUSINESS WIRE)--Sept. 9, 1997--American Technology Corp.

Recent tests in which HSS was measured against traditional loudspeakers proved that HSS provides almost a 30 decibel decibel (dĕs`əbĕl', –bəl), abbr. dB, unit used to measure the loudness of sound. It is one tenth of a bel (named for A. G. Bell), but the larger unit is rarely used. increase in front-to-back directivity at virtually any audio frequency in contrast with conventional loudspeakers, which reproduce sound in a generally omnidirectional In all directions. For example, an omnidirectional antenna can transmit or receive signals in all directions. Contrast with directional. See RF. pattern over much of the audio spectrum. With the advent of surround sound and the explosion in demand for home-theater products, room acoustics have become increasingly critical. Room reflections cause unwelcome multi-path reverberations in the listening environment that often smear or otherwise distort sound. HSS is designed to beam sound directly to a specifically defined listening area thereby reducing room reflections. HSS eliminates the need for speaker enclosures and the requirement to precisely position speakers in a room. Elwood Norris, inventor of HSS Sound and chief technology officer, stated: ``There are several breakthroughs that distinguish HSS reproduction from traditional sound-generation methods. One of the most important is the ability to produce sound in a precisely directed column of air and project sound to a desired listening area thereby reducing the impact of room acoustics. ``HSS Sound delivers beamed sound over long distances in contravention of traditional theories on sound-level attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. . Bringing greatly enhanced directivity to sound, especially low frequencies, offers many opportunities for HSS technology. We can now project and control sound similar to what is done with light.'' Norris added, ``Our objective is to exploit the many advantages of HSS through carefully selected strategic relationships. We continue to enhance the features and capabilities of HSS technology and are working to adapt HSS to large market segments.'' HyperSonic hy·per·son·ic adj. Of, relating to, or capable of speed equal to or exceeding five times the speed of sound. hy Sound is a new technology in audio production that employs ultrasonics ultrasonics, study and application of the energy of sound waves vibrating at frequencies greater than 20,000 cycles per second, i.e., beyond the range of human hearing. in a patents-pending process to produce sound directly in the air. HSS eliminates many forms of distortion and reduces room acoustical effects. It is efficient and lightweight and is cost competitive relative to direct radiating loudspeakers. The laser-like HSS ultrasonic beam can also project sound to virtually any listening environment, creating many new sound applications heretofore impossible with existing speaker technology.
