Models of binaural hearing for sound lateralisation and localisation
The current study suggests two models of binaural hearing, which aim to make predictions for inside- and outside-head localisation of a single sound source in the horizontal plane. Both models consider free-field ITDs and ILDs as the memory of sound localisation to which the target interaural …

Binaural Hearing Effects of Mapping Microphone Array's Responses to a Listener's Head-Related Transfer Functions
… algorithm was added to the HRTF matching, a ‘binaural HRTF matching’ process. The binaural HRTF matching increased the listeners’ performance in perceiving the location of a sound source. With the addition of simulated head movement, the listeners’ perception increased by 20%. An issue with …

Simulating the effects of aging and hearing loss on the masking-level difference
When testing binaural hearing under headphones, the stimulus (signal and noise) delivered to the two ears can either be the same (diotic) or different (dichotic). Once any part of the stimulus is changed between the ears, the signal becomes easier to detect compared to the diotic condition. The …

Binaural sound source localization using machine learning with spiking neural networks features extraction
Human and animal binaural hearing systems are able take advantage of a variety of cues to localise sound-sources in a 3D space using only two sensors. This work presents a bionic system that utilises aspects of binaural hearing in an automated source localisation task. A head and torso emulator …

Binaural interactions in the auditory midbrain with bilateral electric stimulation of the cochlea
… implantation seeks to restore the advantages of binaural hearing to the profoundly deaf by giving them access to binaural cues normally important for accurate sound localization and speech reception in noise. This thesis characterizes binaural interactions in auditory neurons using a cat model of …

Neuromorphic auditory computing: towards a digital, event-based implementation of the hearing sense for robotics
… Sensor. More specifically, the principles of binaural hearing were deeply studied for implementing event-based models to perform real-time sound source localization tasks. Two different approaches were followed to extract inter-aural time differences from event-based auditory signals. On the …

Perceptual cues of consonant sounds and impact of sensorineural hearing loss on speech perception
… the impact of various types of cochlear hearing loss and mask- ing noise on the perception of basic speech sounds based on the information of identified speech cues. A psychoacoustic method, named three-dimensional deep search (3DDS), is developed to identify the perceptual cues of …

Applications of jump processes in epidemiology and neuroscience
… in real time. We also propose a model for binaural hearing, which can be used to extend the maximum likelihood decoder to arbitrary stimuli.

Modeling and Evaluating Human Sound Localization in the Natural Environment
… has greatly advanced our understanding of binaural hearing but leaves us some ways from a complete understanding. In particular, it has been difficult to assess human sound localization in ways that align with humans experience on an everyday basis. This thesis aims to more closely align …

Development and application of an echolocation model inspired by bats
… technique<br/>which was developed based on bat’s hearing system, the effect of auditory processing<br/>on the object discrimination is investigated for both CF (constant frequency) and FM<br/>(frequency modulated) signals respectively. These signals are considered as two representative<br/>types …

Modelling binaural speech intelligibility in spatial noise and reverberation for normal-hearing and hearing-impaired subjects
… stellt die Entwicklung eines Modells der binauralen Sprachverständlichkeit und seine Überprüfung für ausgewählte binaurale Situationen vor. Das Modell wurde für die Vorhersage von binauraler Sprachverständlichkeit in fluktuierendem Rauschen erweitert, und die Gültigkeit der Annahme, dass …

Manatee Sound Localization: Performance Abilities, Interaural Level Cues, and Usage of Auditory Evoked Potential Techniques to Determine Sound Conduction Pathways
Three experiments investigated the ability and means by which Florida manatees determine sound source directionality. An eight-choice discrimination paradigm determined the sound localization abilities of two manatees within a 360° array of speakers. Five conditions were tested including a 3,000 …
