In complex scenes, the identity of an auditory object can build up across seconds. Given that attention operates on perceptual objects, this perceptual buildup may alter the efficacy of selective auditory attention over time. Here, we measured identification of a sequence of spoken target digits presented with distracter digits from other directions to investigate the dynamics of selective atte...

In this paper we propose a game-based virtual reality platform for evaluation of sonification techniques. We study the task of localization of stationary objects in virtual reality using auditory cues. We further explore sonification techniques and compare the performance in this task using the proposed platform. The virtual reality environment is developed using Unity3D (game engine) and an Oc...

This study addresses the neuronal representation of aversive sounds that are perceived as unpleasant. Functional magnetic resonance imaging in humans demonstrated responses in the amygdala and auditory cortex to aversive sounds. We show that the amygdala encodes both the acoustic features of a stimulus and its valence (perceived unpleasantness). Dynamic causal modeling of this system revealed t...

One important principle of object processing is exclusive allocation. Any part of the sensory input, including the border between two objects, can only belong to one object at a time. We tested whether tones forming a spectro-temporal border between two sound patterns can belong to both patterns at the same time. Sequences were composed of low-, intermediate- and high-pitched tones. Tones were ...

In this study, the implementation of creative thinking will be applied to material two variable linear equation systems (SPLDV). The study agreed describe abilities high school students in solving Multiple Solution Task (MST) question reviewed from a learning style. This type research is qualitative description. subject student class VII B SMPN 1 Sambi who has passed SPLDV 2 material, selected ...

When looking for an object in a complex visual scene, Augmented Reality (AR) can assist search with cues persistently pointing the target’s direction. The effectiveness of these be reduced if they are placed at different depth plane to target indicating. To overcome this visual-depth problem, we test adding simultaneous spatialized auditory that fixed location. In experiment manipulated which c...

As you sit in front of this book, reading these words, pause for a moment, listen, and ask yourself: What do I hear? Perhaps you hear some conversations going on in the background, some devices making noises of various kinds (an almost omnipresent feature of the modern world). Or perhaps you are in an unusually quiet place, and there is effectively nothing to hear. Almost certain is that you wo...

In our auditory environment, we rarely experience the exact acoustic waveform twice. This is especially true for communicative signals that have meaning for listeners. In speech and music, the acoustic signal changes as a function of the talker (or instrument), speaking (or playing) rate, and room acoustics, to name a few factors. Yet, despite this acoustic variability, we are able to recognize...

This positron emission tomography study examined the hemodynamic response of the human brain to auditory object feature processing. A continuum of object feature variation was created by combining different numbers of stimuli drawn from a diverse sample of 45 environmental sounds. In each 60 sec scan condition, subjects heard either a distinct individual sound on each trial or simultaneous comb...

The separation of concurrently presented sounds into distinct auditory objects is accompanied by the elicitation of the object-related negativity (ORN) component of the event-related potential (ERP). In the present study, participants were exposed to tone sequences containing not only concurrent (harmonicity), but also sequential cues (similarity to previous stimuli in the series) for auditory ...
