Anonymous web-based experiments are increasingly and successfully used in many domains of behavioral research. However, online studies of auditory perception, especially of psychoacoustic phenomena pertaining to low-level sensory processing, are challenging because of limited available control of the acoustics, and the unknown hearing status of participants. Here, we outline our approach to mitigate these challenges and validate our procedures by comparing web-based measurements to lab-based data on a range of classic psychoacoustic tasks. Individual tasks were created using jsPsych, an open-source javascript front-end library. Dynamic sequences of psychoacoustic tasks were implemented using Django, an open-source library for web applications, and combined with consent pages, questionnaires, and debriefing pages. Subjects were recruited via Prolific, a web-based human-subject marketplace. Guided by a meta-analysis of normative data, we developed and validated a screening procedure to select participants for (putative) normal-hearing status; this procedure combined thresholding of scores in a suprathreshold cocktail-party task with filtering based on survey responses. Headphone use was standardized by supplementing procedures from prior literature with a binaural hearing task. Individuals meeting all criteria were re-invited to complete a range of classic psychoacoustic tasks. Performance trends observed in re-invited participants were in excellent agreement with lab-based data for fundamental frequency discrimination, gap detection, sensitivity to interaural time delay and level difference, comodulation masking release, word identification, and consonant confusions. Our results suggest that web-based psychoacoustics is a viable complement to lab-based research. Source code for our infrastructure is also provided.

There is an increasing global recognition of the negative impact of hearing loss, and its association to many chronic health conditions. The deficits and disabilities associated with profound unilateral hearing loss, however, continue to be under-recognized and lack public awareness. Profound unilateral hearing loss significantly impairs spatial hearing abilities, which is reliant on the complex interaction of monaural and binaural hearing cues. Unilaterally deafened listeners lose access to critical binaural hearing cues. Consequently, this leads to a reduced ability to understand speech in competing noise and to localize sounds. The functional deficits of profound unilateral hearing loss have a substantial impact on socialization, learning and work productivity. In recognition of this, rehabilitative solutions such as the rerouting of signal and hearing implants are on the rise. This review focuses on the latest insights into the deficits of profound unilateral hearing impairment, and current treatment approaches.

Response Feedback

This study investigated the effects of computer-assisted feedback strategies that have been utilized by university students in a technology education curriculum. Specifically, the study examined the effectiveness of the computer-assisted feedback strategy “Knowledge of Response feedback” (KOR), and the “Knowledge of Correct Responses feedback” (KCR) strategy, and compared them with “No feedback” (NR) on students' learning outcomes in technology education. Three intact classes were assigned to one of three conditions: KOR, KCR, or NR (control group). The dependent measure consisted of a 40-item learning outcome test. Learning outcome pretest and posttest data were obtained through the web-based surveys during a 4-week period of instruction. Results showed that using computer-assisted feedback of KOR or KCR in practice exercises as a supplemental strategy is as effective as NR in practice exercises. Technology education instruction with computer-assisted feedback strategies could be a viable option for learning in a favorable direction.

Telehealth has become a viable option for glaucoma screening and glaucoma monitoring due to advances in technology. The ability to measure intraocular pressure without an anesthetic and to take optic nerve photographs without pharmacologic pupillary dilation using portable equipment have allowed glaucoma screening programs to generate enough data for assessment. At home, patients can perform visual acuity testing, web-based visual field testing, rebound tonometry, and video visits with the physician to monitor for glaucomatous progression. Artificial intelligence will enhance the accuracy of data interpretation and inspire confidence in popularizing telehealth for glaucoma.

Evaluation of the speech, spatial and qualities of hearing in unilateral and bimodal cochlear implant users with incomplete partition type II Objective: The aim of this study was to perform a scale-based assessment of the hearing abilities of cochlear implant users with IP type II malformation and normal cochlea, including discrimination, orientation, and positioning of speech and environmental sounds in their environment. Material and Methods: A total of 30 cochlear implant users, 15 participants with IP-II inner ear anomalies and 15 participants with normal cochlea, aged 18-55 years were included in this study. All participants included in the study are unilateral CI and bimodal users. Participants were assessed using the Speech, Spatial, and Hearing Qualities Scale (SSQ). Results: When cochlear implant users with IP-II malformations and cochlear implant users with normal cochlea individually scored auditory abilities, the results were similar. It was observed that bimodal listeners tended to have all subdomains and overall SSQ scores compared to use of unilateral CI. Conclusion: It is very important to benefit from the advantages of binaural hearing in hearing sounds. It is thought that the use of scales as well as routine audiological evaluation batteries in the follow-up processes of cochlear implant users will be beneficial for audiologists. Keywords: Cochlear implant, speech perception, spatial perception, hearing quality

The rapid growth in Indian economy for the next decade is expected to be sphere headed by the startup revolutiondriven by private enterprises. The growth that was witnessed in the last decade could also be largely attributed to MSME. MSME Businesses contributed more than 40% of the growth story of Indian economy. The almost double digit GDP growth achieved between the years 2003-2007 is a result of services and manufacturingsectors, taking off in a big way supported by the startup culture. The startup culture has started showing promising signal of significant contribution in Indian GDP. Particularly in the last three years the starts up fever has gripped this country and have the potential to catapult it into the planned path of economic supremacy. Angel investors, venture capitalist and private equity players in India and from the West have taken a keen interest in funding this technologically and financially viable option on a larger scale. However there exist gapsat the bottom of the pyramid where these technocrats are struggling to raise pre-seed capital which is essential to develop and test their prototype to prove their commercial viability.There exist a big gap between the demand and supply in terms of fund availability. This gap can be easily bridged with the help of popularly emerging option known as crowd funding. Crowd funding has become one of the most talked about avenues for financing of startup pre -seed capital requirement in the past. It has become very popular in the matured economies of the West, particularly in USA, where Web based platforms are emerged as reliable intermediary to bring suppliers and seekers of funds together. It has already begin in India and has provoked a healthy debate and discussion initiated by SEBI to its discussion paper. In this backdrop,crowd funding is an acceptable fund viable option for the pre-seed capital required in IT startups. This discussion proves the importance of crowd funding under regulatory framework and it has made the study not only relevant but also contemporary.

Tailored Approach

Mobile tools are increasingly available to help individuals monitor their progress toward health behavior goals. Commonly known commercial products for health and fitness self-monitoring include wearable devices such as the Fitbit© and Nike + Pedometer© that work independently or in conjunction with mobile platforms (e.g., smartphones, media players) as well as web-based interfaces. These tools track and graph exercise behavior, provide motivational messages, offer health-related information, and allow users to share their accomplishments via social media. Approximately 2 million software programs or “apps” have been designed for mobile platforms (Pure Oxygen Mobile, 2013), many of which are health-related. The development of mobile health devices and applications is advancing so quickly that the Food and Drug Administration issued a Guidance statement with the purpose of defining mobile medical applications and describing a tailored approach to their regulation.
