FLY-EAR INSPIRED MINIATURE SENSOR SYSTEM FOR TWO-DIMENSIONAL SOUND SOURCE LOCALIZATION
A micro-scale sound localization sensor is developed and studied in this thesis to address the fundamental challenge of miniaturizing sound localization systems. When miniaturizing a microphone array, there is a critical size limitation at which the array will be unable to localize the sound source …

Source localization from voice signals
Indoor localization remains an open field of research, due to its utility and unresolved challenges. This thesis focuses on sound source localization using a small microphone array. Practically speaking, the aim is to allow smart voice assistants, such as Amazon Echo or Google Home, which possess a …

The Effect of Motor Responses Versus Verbal Responses on Sound Localization Accuracy in Young Children with Normal Hearing
<p>Rationale. Sound localization is the ability to pinpoint the origin of a sound source within an auditory space. This ability is essential for safety, orientation, and communication. Poor sound localization abilities, especially in young children, can have a negative impact on academics and …

Neuromorphic auditory computing: towards a digital, event-based implementation of the hearing sense for robotics
… in robots through the implementation of an open-source neuromorphic cochlea, event-based models of primary auditory nuclei, and their potential use for real-time robotics applications. First, the main gaps when working with neuromorphic cochleae were identified. Among them, the accessibility and …

Sound localization and interaural time sensitivity with bilateral cochlear implants
… common as clinicians attempt to provide better sound-source localization and speech reception in noise for cochlear implant (CI) users. While some improvement over the abilities of monolateral implantees has been documented, bilateral performance for CI users is far from that achieved with …

Understanding and Mimicking the Fly's Directional Hearing: Modeling, Sensor Development, and Experimental Studies
Microphone arrays have been widely used in sound source localization for many applications. In order to locate the sound in a discernible manner, the separation between microphones needs to be greater than a critical distance, which poses a fundamental constraint for the miniaturization of …
