摘要： In a room with strong low-frequency modes the control of excessively long decays is problematic or impossible with conventional passive means. In this patent application a systematic methodology is presented for active modal equalization able to correct the modal decay behaviour of a loudspeaker-room system. Two methods of modal equalization are proposed. The first method modifies the primary sound such that modal decays are controlled. The second method uses separate primary and secondary radiators and controls modal decays with sound fed into at least one secondary radiator. Case studies of the first method of implementation are presented.

摘要翻译： 在具有强低频模式的房间中，过度长衰减的控制是常规被动方式的问题或不可能的。 在该专利申请中，提出了一种用于有效模态均衡的系统方法，其能够校正扬声器室系统的模态衰减行为。 提出了两种模态均衡方法。 第一种方法修改主声音，使模态衰减得到控制。 第二种方法使用单独的主和辅助辐射器并且控制模态衰减，声音馈送到至少一个次级辐射器。 介绍了第一种实施方法的案例研究。
