Abstract
A joint spectral gain adaption module, which comprises: an aided-ear loudness model, wherein an aided-ear loudness spectrum is obtained by performing computations on an aided-ear threshold elevation profile and a spectrum selected from the group consisting of an input spectrum and a first spectrum derived from the input spectrum; a bare-ear loudness model, wherein a bare-ear loudness spectrum is obtained by performing computations on a bare-ear threshold elevation profile, and a modified spectrum previously obtained; and a spectrum shaping sub-module, wherein the modified spectrum previously obtained is passed to the bare-ear loudness model as an input, and a modified spectrum and a linear spectral gain vector are obtained by performing computations on the input spectrum, the bare-ear loudness spectrum, and a loudness spectrum selected from the group consisting of the aided-ear loudness spectrum and a first loudness spectrum derived from the aided-ear loudness spectrum.
