Definitions

  • the invention relates to a measuring method for aurally correct Quality assessment of audio signals according to the generic term of claim 1.
  • the filter bank 3 consists of an arbitrarily selectable number of filter pairs for test and reference signal 1a, b or 1d, c (values between 30 and 200 are sensible).
  • the filters can be distributed evenly on largely any pitch scales.
  • a suitable pitch scale is e.g. B.
  • the following approximation proposed by Schroeder: e.g. / Bark 7 arsinh f / Hz 650
  • Eq. 11 has been designed here to provide the specific loudness of the disturbance when there is no masker and to provide approximately the ratio between disturbance and masker when the disturbance is very small in relation to the masker.
