The processing of concurrent sounds based on inharmonicity and asynchronous onsets: An object-related negativity (ORN) study

This study addresses the processing of concurrent sounds based on inharmonicity and onset asynchrony cues. We used harmonic complex sounds with one component starting marginally (40 ms) or considerably (500 ms) earlier than the complex and being slightly (3%) or strongly (13%) inharmonic. To index sound segregation of concurrent events, we measured the object-related negativity (ORN) component of the event-related potential. We contrasted two...
