On the Relevance of the Differences Between HRTF Measurement Setups for Machine Learning [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2022 As spatial audio is enjoying a surge in popularity, data-driven machine learning techniques that have been proven successful in other domains are increasingly used to process head-related transfer function measurements.

CAAI Transactions on Intelligence Technology, Volume 7, Issue 3, Page 446-454, September 2022., 2022 Abstract This article proposes a deep neural network (DNN)‐based direct‐path relative transfer function (DP‐RTF) enhancement method for robust direction of arrival (DOA) estimation in noisy and reverberant environments. The DP‐RTF refers to the ratio between the direct‐path acoustic transfer functions of the two microphone channels.

Journal of Thrombosis and Haemostasis, Volume 20, Issue 4, Page 866-876, April 2022., 2022 Abstract Background Most tissue factor (TF) activity assays are based on measurement of factor X (FX) activation by TF in the presence of factor VII (FVII)/FVIIa. This requires long incubation, which may result in TF‐independent activity of FX and inaccurate measurement of TF activity.

Low-Order Spherical Harmonic HRTF Restoration Using a Neural Network Approach
Applied Sciences, 2020 Spherical harmonic (SH) interpolation is a commonly used method to spatially up-sample sparse head related transfer function (HRTF) datasets to denser HRTF datasets.

Folk Music Audio Enhancement Method Combining Internet of Things and GA
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 The current methods of music sound enhancement mainly use the way of enhancing the intensity of the sound source, which ignores the spatial noise cancellation of the human ear, resulting in poor sound enhancement effect. Therefore, this paper proposes an audio enhancement method for folk music combining Internet of Things and GA.

Measurement of Head-Related Transfer Functions: A Review
Applied Sciences, 2020 A head-related transfer function (HRTF) describes an acoustic transfer function between a point sound source in the free-field and a defined position in the listener’s ear canal, and plays an essential role in creating immersive virtual acoustic ...

Structural composition and decomposition of HRTFs [PDF]
Proceedings of the 2001 IEEE Workshop on the Applications of Signal Processing to Audio and Acoustics (Cat. No.01TH8575), 2002 The analysis and modeling of the response of parts of the body provides valuable insight into many features of the head-related transfer function (HRTF). In spatial sound simulations, partial models, such as the spherical head model, can also generate simple and effective approximate localization cues. We consider the composition of an approximate HRTF

Human Behavior and Emerging Technologies, Volume 2022, Issue 1, 2022., 2022 Obstacle perception using sound is the ability to detect silent objects, such as walls and poles. It is very important for blind people to recognize their environment using acoustic information through their auditory sense when walking or conducting various daily activities.

Compression of Head-Related Transfer Function Based on Tucker and Tensor Train Decomposition
IEEE Access, 2019 Head-related transfer function (HRTF) plays an important role in three-dimensional spatial sound system. However, the direct application of a large amount of original HRTF data would involve a great deal of computational burden, especially for high ...
