摘要:
A method for setting parameters for individual adaptation of an audio signal has different levels for outputting a plurality of first sound signals of different sound pressure levels in different frequency ranges to an individual, and for different frequency ranges. A sub-step of playing a plurality of first audio signals to an individual; Obtaining, from an individual, feedback per frequency range of different frequency ranges, which of the plurality of first acoustic signals exceeds an individual listening threshold; And a level for individual listening thresholds per frequency range of different frequency ranges, wherein a plurality of first available feedbacks characterizing the associated first acoustic audio signal per frequency range of different frequency ranges as acoustic audio signals exceeding individual listening thresholds are available. Performing a first listening test, comprising a sub-step of using the lowest of the different levels of the audio signals, and considering the sound adaptive characteristic map to output the post-processed second acoustic signal to the individual Playing the second audio signal according to the total volume level selected by the sub-step; And sub-steps of varying the sound adaptation characteristic map until the individual indicates that they do not wish to further change the sound adaptation characteristic map by interaction, and comprising: The adaptive characteristic map defines individual boosts and/or individual cuts of the output level for each input level for different frequency ranges, and the levels for individual listening thresholds per frequency range of different frequency ranges are the minimum in the sound adaptive characteristic map. Used as output levels.오디오 신호의 개별 적응을 위한 파라미터들을 설정하기 위한 방법은, 상이한 주파수 범위들에서의 상이한 사운드 압력 레벨들의 복수의 제1 음향 신호들을 개인에게 출력하기 위하여 상이한 레벨들을 갖는, 그리고 상이한 주파수 범위들에 대한 복수의 제1 오디오 신호들을 개인에게 플레이하는 하위단계; 개인으로부터, 복수의 제1 음향 신호들 중의 어느 것이 개별 리스닝 임계치를 초과하는지 상이한 주파수 범위들의 주파수 범위당 피드백을 획득하는 하위단계; 및
