Movements in Binaural Space: Issues in HRTF Interpolation and Reverberation, with applications to Computer Music
… of the minimum-phase plus linear delay model for HRTF representation and interpolation is offered. A rigorous analysis of threshold based phase unwrapping is also performed. The results and conclusions drawn from these analyses motivate the development of two novel methods for HRTF representation …

Binaural Hearing Effects of Mapping Microphone Array's Responses to a Listener's Head-Related Transfer Functions
… human subject’s Head-Related Transfer Function (HRTF). The mapping of the response is first explored with a ‘monaural HRTF matching’ that filters the response independent of the arrival angles. For arbitrary array geometry with the listener external to the acoustic, the monaural HRTF matching did …

Characterization of the head-related transfer function using chirp and maximum length sequence excitation signals
… of the head-related transfer function (HRTF) for the Knowles electronic manikin for acoustic research (KEMAR), resulting in remarkably low relative error between the two measurement methods. Due to the low relative error, it is asserted that applying both methods in experiments involving …

Approach to Safety Improvement: Focusing on Better Care (Fall Prevention in Medical Surgical/Intermediate Care Unit)
… all patients that are high risk to fall (HRTF) prior to their admittance or transfer to Medical Surgical/Intermediate Care Unit and throughout their hospital stay until they are discharged. In addition, a fall prevention action plan was generated for all staff members to follow to ensure …

CUSTOMIZING IMMERSIVE SPATIAL AUDIO: FROM INDIVIDUALIZED BINAURAL RENDERING TO REAL-VIRTUAL ACOUSTIC BLENDING
… alla testa (head-related transfer functions, HRTF) in base ai parametri antropometrici del padiglione auricolare. La tesi presenta anche nuovi parametri del padiglione auricolare per caratterizzarne più in dettaglio l'anatomia, migliorando così l'individualizzazione delle HRTF. Inoltre, …

Improving the spatial acoustic experience through calibration
… each user’s head-related transfer function (HRTF), which is a challenging and tedious process. We explore methods to improve the spatial acoustic experience in the absence of personalized HRTFs. We present a system composed of a calibration process and an application. We evaluate the …

Characterization of acoustic head-related transfer functions for nearby sources
Head Related Transfer Functions (HRTF) for nearby sources were characterized for human subjects and the Knowles Electronics Manikin for Acoustic Research (KEMAR). The HRTFs were measured in several reverberant room conditions for sound source positions at 0, 45, and 90 degrees in azimuth and 15cm …

Development and application of an echolocation model inspired by bats
… the head-related transfer function<br/>(HRTF) of a bat-head cast. It has been reported that a bat changes bandwidth<br/>and duration of its echolocating call as it approaches a target. Adaptive change in the<br/>echolocating calls has been well explained in previous studies in terms of …

Development of a Computationally Efficient Binaural Simulation for the Analysis of Structural Acoustic Data
… and applying Head Related Transfer Functions (HRTFs) to each of the sources, a binaural simulation of this type can be created. Unfortunately, this simulation method requires an extensive amount of computer power and speed for real-time simulation, more so than is available with current …

Validation of a 3-D Virtual Acoustic Prototyping Method For Use In Structural Design
… (ESM), and head-related transfer functions (HRTFs). A tradeoff exists between the accuracy of the auralization process and the number of equivalent sources (and thus computational power) that are required. The goal of this research is to validate (numerically and subjectively) a virtual …

The creation of a binaural spatialization tool
The main focus of the research presented within this thesis is, as the title suggests, binaural spatialization. Binaural technology and, especially, the binaural recording technique are not particu-larly recent. Nevertheless, the interest in this technology has lately become substantial due to the …

Capturing spatial audio from arbitrary microphone arrays for binaural reproduction
Spatial audio has typically been recorded from specialized microphone arrays that are too expensive and unwieldy to incorporate into today's consumer devices. Consumer devices, such as mobile devices, typically use cheap microphones with strict limitations on array geometry. Therefore, in order to …
