“…As these stimuli differ in more than one timbre dimension, a control of a single parameter is not possible with these stimuli. To overcome this limitation, a behavioral test using synthetically sounds was developed [10] and evaluated [11]. With this test, cross-faded (morphed) tones were generated to change only the spectral shape difference in certain steps by linear interpolation of spectral parameters.…”

The identification and discrimination of timbre are essential features of music perception. One dominating parameter within the multidimensional timbre space is the spectral shape of complex sounds. As hearing loss interferes with the perception and enjoyment of music, we approach the individual timbre discrimination skills in individuals with severe to profound hearing loss using a cochlear implant (CI) and normal hearing individuals using a bone-anchored hearing aid (Baha). With a recent developed behavioral test relying on synthetically sounds forming a spectral continuum, the timbre difference was changed adaptively to measure the individual just noticeable difference (JND) in a forced-choice paradigm. To explore the differences in timbre perception abilities caused by the hearing mode, the sound stimuli were varied in their fundamental frequency, thus generating different spectra which are not completely covered by a CI or Baha system. The resulting JNDs demonstrate differences in timbre perception between normal hearing individuals, Baha users, and CI users. Beside the physiological reasons, also technical limitations appear as the main contributing factors.

“…Therefore, we developed a behavioral test which overcomes the limitations of using natural sounds with more than one changing timbre dimension by using synthetically sounds (Rahne et al, 2010). With this test, cross-faded ('morphed') tones were generated to change the timbre difference in certain steps by linear interpolation of spectral parameters.…”
