Abstract:
A sound field device is disclosed that comprises an elevation cue estimator, a low-frequency filter estimator, and a high-frequency filter estimator. The elevation cue-estimator is configured to estimate an elevation cue of a head-related transfer function (HRTF) of at least one listener. The low-frequency filter estimator is configured to estimate one or more low-frequency filter elements based on the elevation cue. The high-frequency filter estimator is configured to estimate one or more high-frequency filter elements based on the elevation cue. An estimation method of the low-frequency filter estimator is different from an estimation method of the high-frequency filter estimator. The one or more low-frequency filter elements and the one or more high-frequency filter elements are for driving an array of loudspeakers to generate an elevated sound impression at a bright zone.

Claim (Index 7):
The sound field device of  claim 1 , wherein a cutoff frequency between the one or more low-frequency filter elements and the one or more high-frequency filter elements is chosen as (Q\u22121)c/4\u03c0r, wherein Q is a number of loudspeakers in the array of loudspeakers, r is a radius of the bright zone, and c is a speed of sound.
