摘要： A system and method for delivering full-bandwidth sound to an audience in an audience space located in front of an acoustically reflective image screen such as a plasma, LCD, LED, or OLED screen. The sound delivery system provides for two separate and spatially displaced sound sources, namely, a high frequency loudspeaker for reproducing high frequency components of the sound associated with images displayed on the acoustically reflective image screen, and a separate low frequency loudspeaker for reproducing low frequency components of the image-associated sound. The high frequency loudspeaker or loudspeakers are positioned in front of the image screen to direct the high frequency components of the sound at the image screen where it is reflected back into the audience space, whereas the low frequency loudspeaker or loudspeakers are positioned at or about the acoustically reflective image screen and direct the low frequency components of the sound toward the audience space which are time-aligned with the high frequency components.

摘要： A filter for correcting phase distortion produced at low frequencies in a loudspeaker system is created by inverting the phase response of the determined complex-valued frequency response of a loudspeaker system. The inverted phase response is obtained by taking the complex conjugate of the phase response. The impulse response for the inverted phase response is obtained by means of an inverse Fourier transform of the inverted phase response. The impulse response provides a linear phase FIR filter having a long filter length. The linear phase FIR filter is applied to the audio signal input to the loudspeaker system. Prior to inverting the phase response, the determined complex-valued frequency response of a loudspeaker system can be subjected to high frequency blanking and polynomial smoothing. Also, the linear phase FIR filter can be subjected to a window function prior to applying the filter to the audio signal.

摘要： A method for correcting magnitude and phase distortion in open ear hearing devices includes determining the insertion effect of the hearing device (12) substantially at the ear drum (11) when in the ear. Both the magnitude and phase response of the complex insertion transfer function (ITF) are corrected when the transfer function to the ear drum substantially matches the transfer function without the hearing device in place.

摘要： An acoustically absorptive panel comprises a forward airspace bounded by an acoustically transparent front fabric stretch-mounted on a support frame, and the front face of a porous acoustical absorber, the forward air space, the front fabric and the porous absorber collectively acting as acoustical absorbing chamber, wherein oppositely disposed end panels of the front fabric extend around opposing side frame members of one or more frame structures of the support frame and are connected to a pair of spaced apart retaining struts disposed between the side frame members, the distance between the retaining struts adjustable by rotating one or more threaded tension adjusters thereby stretching or relaxing the front fabric across the support frame to adjust the frequency at which sound absorption will be maximized.

摘要： A loudspeaker having a vented enclosure with at least one tuning port includes a fan inside the vented enclosure, which is positioned to produce airflow for cooling the magnetic assembly of the loudspeaker's transducer. Airflow within said vented enclosure is produced such that air within the enclosure is exchanged with outside air through the at least one tuning port. Typically, the vented enclosure will have two tuning ports wherein outside air drawn into the enclosure through one of the tuning ports is circulated out through the other tuning port. Preferably, the outside air drawn in through one tuning port is circulated directly around the transducer magnetic assembly for greatest heat dissipation.

摘要： An improved filtering system for loudspeaker equalization is comprised of two filtering sections, a single pole filtering section having single pole filters for shaping the frequency response of the audio signal over the operative bandwidth of the equalized loudspeaker system, and a parametric filtering section that provides for localized parametric equalization for compensating for room or other environmental resonances. The filtering system of the invention can be used to create a wide variety of useful filter shapes, while minimizing phase distortion that can harm the transient response of phase-aligned loudspeakers of a loudspeaker system.

摘要： A loudspeaker system has a high frequency channel for driving a horn loaded high frequency transducer, and a low frequency channel for driving a low frequency transducer. A signal processing circuit is provided which has at least one first order and at least one second order cross-over circuit portion in the high channel and at least one first order and at least one second order cross-over circuit portion in the low frequency channel. These cross-over portions produce a cross-over frequency range for the loudspeaker system that is below the cut-off frequency of the horn. The signal processing circuit, including its cross-over circuit portions and in conjunction with the design of the expansion walls of the horn, extends vertical beamwidth control of the acoustic output of the loudspeaker system at the loudspeaker system's lower frequency range.

摘要： A web hosted system and user interface in a client-server architecture permits audio designers to perform acoustic prediction calculations from a thin client computer. A client computer or other Internet connect device having a display screen is used by an audio professional to access via the Internet a host computer which performs acoustic prediction calculations and returns results of the calculations to the client. The results of the calculations are returned in the form of data visualizations, such as an area view showing visualizations of sound pressure levels within a defined space, an impulse view showing the time domain response at a defined location, and/or a frequency domain view showing the frequency response at a defined location. Calculations are performed based on user-defined inputs, such as speaker type and location, sent to the host computer from the client computer and based on retrieval of loudspeaker data from one or more databases accessible by the host computer.
