Influence of Implantable Hearing Aids and Neuroprosthesison Music Perception

Figure 1

Amplitude spectrums of the standard (upper row) and probe stimuli waveforms (lower row). The amplitude of the fundamental frequency ( 𝑛 = 0 ) remains constant, while the amplitudes 𝐴 of the even (white circles) and odd harmonics (black circles) were cross-faded by the parameter α. Applying no cross-fading ( 𝛼 = 1 ), the amplitudes are maximal different which results in a maximal timbre difference. The amplitudes of all harmonics are equal at maximal cross-fading ( 𝛼 = 0 ) which results in stimuli with no timbre difference.
