Previous research has shown that podcasts are most frequently consumed using mobile listening devices across a wide variety of environmental, situational, and social contexts. To date, no studies have investigated how an individual's environmental context might influence their attentional engagement in podcast experiences. Improving understanding the contexts which episodes take place, they affect listener engagement, could be highly valuable to researchers producers working fields...

Psychophysical tests of spectro-temporal resolution may aid the evaluation methods for improving hearing by cochlear implant (CI) listeners. Here STRIPES (Spectro-Temporal Ripple Investigating Processor EffectivenesS) test is described and validated. Like speech, requires both spectral temporal processing to perform well. Listeners discriminate between complexes sine sweeps which increase or decrease in frequency; difficulty controlled changing stimulus density. Care was taken minimize...

This study simulated the effect of unlinked automatic gain control (AGC) and head movement on output levels resulting inter-aural level differences (ILDs) produced by bilateral cochlear implant (CI) processors. The angular extent velocity movements were varied in order to observe interaction between AGC movement. Static, broadband input ILDs greatly reduced high-ratio, slow-time-constant used. size head-movement-induced dynamic depended more than position source. profiles dynamic, very...

Abstract Cochlear implants (CIs) are neuroprostheses that partially restore hearing for people with severe-to-profound loss. While CIs can provide good speech perception in quiet listening situations many, they fail to do so environments interfering sounds most listeners. Previous research suggests this is due detrimental interaction effects between CI electrode channels, limiting their function convey frequency-specific information, but evidence still scarce. In study, an experimental...

This paper presents the results of objective tests to assess insertion loss and gain performance three true wireless earbuds that featured both active noise cancellation (ANC) hear-through functionality. An acoustic test fixture (ATF) was used examine earbuds’ attenuation boosting broadband noise, linearity for different presentation levels, consistency over time. The show devices are capable a wide range boosting, with modes providing significant levels in frequencies considered important...

While centred on the medium of audio, podcasts are often a multimedia concern, and one that has become hugely popular in recent years, though relatively little is known about perspectives podcast creators their visions innovation. This article details results an exploratory study conducted to enhance our understanding potential innovation field podcasting. Sixteen were interviewed work what they wanted from next-generation podcasts, order understand requirements expectations tools could be...

Sound sources at the same angle in front or behind a two-microphone array (e.g., bilateral hearing aids) produce time delay and two estimates for direction of arrival: A front-back confusion. The auditory system can resolve this issue using head movements. To confusion hearing-aid algorithms, movement was measured an inertial sensor. Successive time-delay between microphones are shifted clockwise counterclockwise by aggregated histograms. histogram with largest peak after multiple predicted...

The signal-to-noise ratio (SNR) benefit of hearing aid directional microphones is dependent on the angle listener relative to target, something that can change drastically and dynamically in a typical group conversation. When new target signal significantly off-axis, lead slower orientation, more complex movements, reversals. This raises question whether there an optimal design for microphones. In principle ideal microphone would provide user with sufficient directionality help speech...

In this paper we propose a novel multi-channel algorithm to separate simultaneous speakers in an environment where the microphone array is subject movement. When microphones are mounted person's head, for instance, movements can lead ambiguities with respect sources and distortions processed signal. The proposed system estimates direction-of-arrival of speaker's signals relative updates these using inertial measurement unit (IMU). A GMM-based localization model used compute posterior...

We simulated the effect of several automatic gain control (AGC) and AGC-like systems head movement on output levels, resulting interaural level differences (ILDs) produced by bilateral cochlear-implant (CI) processors. The AGC included unlinked AGCs with a range parameter settings, linked AGCs, two proprietary multi-channel used in contemporary CIs. results show that over values clinically, parameters most strongly affect dynamic ILDs are release time compression ratio. Linking preserves at...

Dynamic-range compression is used in cochlear implants (CIs) to compensate for the greatly reduced dynamic range of CI listeners. It has been found that unlinked bilateral hearing aids (HAs) can affect spatial location sounds, reducing interaural level differences (ILDs) and causing sound sources appear closer 0° azimuth and/or more diffuse (Wiggins Seeber, 2011). The compressors processors are often much stronger than (e.g., ratios 12:1 vs. ≤3:1 HAs). We investigated effect on monaural...

Normal-hearing (NH) listeners can use level differences to segregate pairs of vocoded sentences that are presented interleaved frequency channels; performance is better at both positive and negative target-to-masker ratios (TMRs) compared a TMR 0 dB (Ihlefeld Shinn-Cunningham, 2008). The present study investigated whether unilateral cochlear-implant (CI) users could also alone two sentences. Due the greatly reduced resolution increased thresholds CI users, were in time sequentially. Boston...
