“…They observe a linear additivity of both effects, showing that the subjects profited from both harmonicity and binaural information. This is not in line with the results of Krumbholz et al (2009), probably due to Klinge et al (2011) measuring in the free field, where control of binaural cues available to the subjects is difficult. The linear additivity of modulation based and binaural cues, however, was also observed by Epp and Verhey (2009a), who found a linear combination of comodulation masking release (Hall et al, 1990) and binaural masking level difference (BMLD, e.g., Jeffress et al, 1956).…”

“…In binaurally unmasked conditions, the subjects were not able to determine the musical interval in the stimuli and had a worse modulation detection performance as compared to diotic conditions. Thus, Krumbholz et al (2009) conclude that binaural processing precedes temporal modulation (i.e. periodicity) processing, with an integration stage that degrades temporal modulation information.…”

“…Several studies have investigated harmonicity or modulation and binaural processing in combination, but come to different and partially contradiction conclusions. Krumbholz et al (2009) studied the ability of subjects to perform modulation detection tasks or musical interval recognition tasks above threshold or in binaurally unmasked conditions (i.e. the stimuli could on be detected to to interaural differences in the masker).…”

“…A diotic experiment by Klein-Hennig et al (2012) with the same adaptive procedure and similar stimuli, but random phases in each interval, found slightly smaller masking release by mistuning. Further evidence regarding the joint processing of binaural and harmonic features was provided by Krumbholz et al (2009), who used headphone experiments that allowed for a strict control of interaural parameters and could thus yield more precise findings on ITD processing. They found that subjects had difficulties to perform musical interval recognition (MIR) tasks with binaurally unmasked complex tones.…”

“…Since their complex tones were unresolved, the authors suggested that the temporal envelope fluctuations that would convey the required periodicity information were not accessible to the auditory system in binaurally unmasked conditions. According to Krumbholz et al (2009), this hints at a processing scheme in which binaural processing precedes pitch processing, with a temporal integration step in between that leads to the observed MIR performance decrease.…”

The ability of the human auditory system to function under unfavorable acoustic conditions, for example focusing on a single talker in a multi-talker environment with background noise and reverberation, is well known (e.g., Cherry, 1953;Kaiser and David, 1960). The theory of auditory scene analysis (ASA, Bregman, 1994) states that the auditory system actively and passively groups several signal features into internal representations of sound sources. This separation helps in tasks like understanding speech in noise or tracking the movement of a sound source. Two of the important signal features are binaural cues derived from a joint processing of the signals received at both ears and pitch or harmonicity, as, e.g., generated by voiced speech sounds (Darwin and Carlyon, 1995). Binaural cues give information about the location and movement of a sound source, while harmonicity processing enables grouping of signal energy according to a fundamental frequency (F0), which helps for example in the separation of different voices. As the signals of interest in auditory scene analysis (voiced speech, animal calls, music) are often periodical (e.g., Fletcher, 1992), the aim of this thesis is to provide psychophysical data and develop and evaluate models for binaural and harmonic processing of periodic signals.The first part of this thesis deals with the processing of interaural time differences (ITDs) in signals with a periodic envelope. Here, a custom periodic envelope is constructed consisting of several segments. The influence of each envelope segment on the sensitivity to ITDs is measured in psychophysical experiments. The ability of an established model for ITD sensitivity (Bernstein and Trahiotis, 2002) to predict the data is evaluated and the model is extended by principles of neuronal adaptation to improve model performance. This is of particular interest as it offers valuable hints on the binaural processing of voiced speech sounds at high frequencies and possible coding strategies for binaural hearing aids or cochlear implants.The second and third part deal with combined processing of harmonicity and ITDs. The second part establishes the method of measuring detection thresholds in harmonicity research. In psychophysical experiments, the ability of subjects to detect a single target component embedded in a tone complex is tested, while the target tone is in harmonic or mis-3 tuned relationship to the masking tone complex. Based on this method, the third part of this thesis reports on combination experiments, where the target tone is additionally presented with an interaural phase difference (IPD). An auditory computer model based on amplitude modulation processing and equalization-cancellation (Durlach, 1963) is used to predict the psychophysical results. Various hypotheses on the combination of binaural and harmonicity information are tested against the human and model data. The results of both studies shed light on the combined processing of two important signal features in ASA and are of high relevanc...

Auditory research has a rich history of combining experimental evidence with computational simulations of auditory processing in order to deepen our theoretical understanding of how sound is processed in the ears and in the brain. Despite significant progress in the amount of detail and breadth covered by auditory models, for many components of the auditory pathway there are still different model approaches that are often not equivalent but rather in conflict with each other. Similarly, some experimental studies yield conflicting results which has led to controversies. This can be best resolved by a systematic comparison of multiple experimental data sets and model approaches. Binaural processing is a prominent example of how the development of quantitative theories can advance our understanding of the phenomena, but there remain several unresolved questions for which competing model approaches exist. This article discusses a number of current unresolved or disputed issues in binaural modelling, as well as some of the significant challenges in comparing binaural models with each other and with the experimental data. We introduce an auditory model framework, which we believe can become a useful infrastructure for resolving some of the current controversies. It operates models over the same paradigms that are used experimentally. The core of the proposed framework is an interface that connects three components irrespective of their underlying programming language: The experiment software, an auditory pathway model, and task-dependent decision stages called artificial observers that provide the same output format as the test subject.
