Cochlear Implantation in Autoimmune Inner‐Ear Disease: Outcome and Patient‐Reported Benefit

The Laryngoscope, EarlyView.
This study demonstrates that patients with secondary autoimmune inner‐ear disease (AIED) achieve significant improvements in speech perception and quality of life following cochlear implantation. Although AIED patients may show slightly lower performance in noisy environments compared to controls, their subjective hearing benefit converges with matched

Multi‐Frequency Electrocochleography Results in Fewer Drop Alarms During Cochlear Implant Insertion

The Laryngoscope, EarlyView.
A novel multi‐frequency electrocochleography (ECochG) algorithm used during cochlear implant electrode insertion is associated with fewer drop alarms and an increase in optimal insertion track patterns. Multi‐frequency ECochG may provide a more accurate assessment of the cochlear microenvironment when compared to single‐frequency ECochG.

An approach for localizing abnormal sound sources in converter stations using mobile microphone arrays

Zhejiang dianli
The acoustic signals generated by power equipment such as converter transformers and AC filters tend to contain crucial status information. Traditional methods relying on manual auscultation to locate equipment faults suffer from subjectivity， low ...

A New Multichannel Microphone Technique for Effective Perspective Control

, 2011
This paper introduces a new multichannel microphone technique that was designed to produce multiple listener perspectives. A listener perspective paradigm and the related spatial attributes are also proposed for the evaluation of spatial quality in ...

Clustered blind beamforming from ad-hoc microphone arrays

, 2010
Microphone arrays have been used in various applications to capture conversations, such as in meetings and teleconferences. In many cases, the microphone and likely source locations are known \emph{a priori}, and calculating beamforming filters is ...

A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

Limnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...

Nonlocal active sound control for composite regions

Mathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Arc‐ZTE: Continuously‐Slewed Zero‐TE Imaging With Incoherent Temporal Sampling for Near‐Silent Dynamic MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable flexible dynamic and DCE MRI with low acoustic noise and high spatiotemporal resolution using zero echo time (ZTE) imaging. Methods This work proposes Arc‐ZTE, a technique in which the readout gradients of ZTE are continuously‐slewed to form arcs in k‐space that are sequentially rotated to yield an incoherent trajectory ...

Clustering of ad-hoc microphone arrays for robust blind beamforming

, 2010
This paper proposes a clustered approach for blind beamfoming from ad-hoc microphone arrays. In such arrangements, microphone placement is arbitrary and the speaker may be close to one, all or a subset of microphones at a given time.
