This paper discusses acoustic feedback effects in active noise control (ANC) and proposes an improved performance online adaptive feedback canceller (AFC). The online AFC is ineffective if the noise input is narrowband. The proposed method uses the prewhitening filter in the weight adaptation path of both AFC and ANC. The computer simulations show that the proposed method of ANC with online AFC...

Presenting information acoustically has become increasingly interesting for technique training and control in elite sport. In rowing, acoustic feedback is a new and promising application to optimize the boat motion. By taking advantage of auditory perception, which is particularly sensitive to temporal resolution, the physics-based movements are mapped to acoustic parameters using Parameter Map...

Studies of speech sensorimotor learning often manipulate auditory feedback by modifying isolated acoustic parameters such as formant frequency or fundamental frequency using near real-time resynthesis of a participant's speech. An alternative approach is to engage a participant in a total remapping of the sensorimotor working space using a virtual vocal tract. To support this approach for study...

Force-feedback devices can provide haptic feedback during interaction with physical models for sound synthesis. However, low-end devices may not always provide high-fidelity display of the acoustic characteristics of the model. This article describes an enhanced handle for the Phantom Omni containing a vibration actuator intended to display the highfrequency portion of the synthesized forces. M...

As a result from modeling cortical processes of self-organization occuring during speech acquisition, a comprehensive neural model of speech production has been developed by using self-organizing neural networks and feedforward neural networks. This model is capable of generating acoustic speech signals and sensory feedback signals by using a high quality 3-dimensional articulatory-acoustic spe...

The olivocochlear (OC) pathway is the source of major feedback control of ascending acoustic information. Two main patterns of axonal branching are evident at this and other levels of the auditory pathway: long-distance collaterals and branches involved in feedback-control loops. Only a minority of OC neurons project to both cochlea, consistent with a role for the system in sound localization. ...

Modifying the vocal tract alters a speaker's previously learned acoustic-articulatory relationship. This study investigated the contribution of auditory feedback to the process of adapting to vocal-tract modifications. Subjects said the word /tas/ while wearing a dental prosthesis that extended the length of their maxillary incisor teeth. The prosthesis affected /s/ productions and the subjects...
