Educators in medical schools around the world are presently experimenting with innovative ways of using web-based learning to supplement existing teaching and process. We have recently used a popular open-source course management system (CMS) called modular object-oriented dynamic environment (Moodle) construct an online site (DPhysiol) facilitate our face-to-face physiology group first-year students Bachelor Medicine Surgery program. The integration Moodle into was assessed log activity,...

The usage of personal listening devices (PLDs) is associated with risks hearing loss. aim this study to evaluate the effects music exposure from these on high-frequency thresholds PLD users.A total 282 young adults were questioned regarding their habits and symptoms listening. Their audiogram determined at high (3-8 kHz) frequencies extended (EHFs, 9-16 kHz). preferred volumes users used compute overall 8-h equivalent levels (LAeq8h).Approximately 80% subjects regular users. Of these, 20.1%...

Animal models have demonstrated that mild hearing loss caused by acoustic trauma results in spontaneous hyperactivity the central auditory pathways. This has been hypothesized to be involved generation of tinnitus, a phantom sensation. We recently shown such hyperactivity, recorded inferior colliculus, is still dependent on cochlear neural output for some time after recovery (up 6 weeks). now studied capacity an intrinsic efferent system, i.e., olivocochlear alter hyperactivity. system known...

Abstract The medial olivocochlear (MOC) system, which originates in the brainstem and projects to outer hair cells cochlea, is thought be involved improving signal detection noisy backgrounds. This proposition arises from observation that input–output functions of auditory primary afferent fibres pure tones recorded a continuous background noise are unmasked by MOC activation, dynamic range, supported both animal human behavioural experiments. However, it not known how unmasking effects...

Objectives This two-part pilot study investigated the feasibility of using a frequency selectivity measure (TFS) to develop novel hearing screening test for cooperative adults. Study 1 determined optimal masker level, while 2 assessed reliability self-administered TFS prototype performed at selected level.

Objective The ear's spectral resolution or frequency selectivity (FS) is a fundamental aspect of hearing but not routinely measured in clinical practice. This study evaluated simplified FS testing procedure for use by replacing the time-consuming two-interval forced choice (2IFC) method with limits (MOL) carried out using custom-made software and consumer-grade equipment.

Objective To undertake calibration and preliminary validation of a custom-designed computer-based screening audiometer connected to consumer insert phone-earmuff combination for adult pure tone audiometry.Design Part 1 involved electroacoustic measurement biological laptop-earphone pair used the audiometry (CBA). 2 compared CBA thresholds obtained without sound booth with those measured using gold-standard clinical audiometry.Study sample 17 young normal-hearing volunteers (Part 1) 43 normal...

Consumer-grade insert earphones (IEs) can be utilised for audiometry, but their calibration values and threshold reliability may differ from the audiometric IE. This study measured equivalent sound pressure levels (ETSPLs), test-retest variation when a consumer IE (Sennheiser CX100) was fitted with: (1) silicone stock ear tips that came along with earphone, (2) replacement foam (KZ acoustics) (3) otoacoustic emission (OAE) probe tips.
