Hearing screening tests based on pure-tone audiometry may be conducted mobile devices, provided that the devices are specially calibrated for purpose. Calibration consists of determining reference sound level and can performed in relation to hearing threshold normal-hearing persons. In case by manufacturer, together with bundled headphones, calculated once all same model.This study aimed compare measured a device was using model-specific, biologically determined obtained audiometry.Trial...

Potential methods of application self-administered Web-based pure-tone audiometry conducted at home on a PC with sound card and ordinary headphones depend the value measurement error in such tests.The aim this research was to determine hearing threshold determined way described above identify analyze factors influencing its value.The evaluation made three series: (1) tests clinical audiometer, (2) self-tests done specially calibrated computer under supervision an audiologist, (3) home. The...

Hearing tests carried out in home setting by means of mobile devices require previous calibration the reference sound level. Mobile with bundled headphones create a possibility applying predefined level for particular model as an alternative to calibrating each device separately.The objective this study was determine sets composed and headphones.Reference levels Android-based were determined using open access phone app biological calibration, that is, relation normal-hearing threshold. The...

Online hearing tests conducted in home settings on a personal computer (PC) require prior calibration. Biological calibration consists of approximating the reference sound level via threshold person with normal hearing.The objective this study was to identify error proposed methods biological calibration, their duration, and subjective difficulty conducting these PC.Seven have been for measuring coefficients. All measurements were performed normal-hearing person. Three determining basis...

Background In addition to the aging process, risk factors for hearing loss in adults include, among others, exposure noise, use of ototoxic drugs, genetics, and limited access medical care. Differences these are bound be reflected prevalence loss. Assessment can easily carried out on a large scale at low cost using mobile apps. Objective This study aimed conduct worldwide assessment differences between countries group device users. Methods Hearing tests were conducted open-access...

The aim of the research was to evaluate feasibility measuring bone conduction hearing threshold using self-administered mobile audiometry.

Abstract Sensory deficits in one modality lead to functional changes of brain structures. Neural reorganization may result sensory compensation and enhanced performance sensitivity tests. Many studies investigated how deafness affects functioning the intact senses. Overall, their results remain inconclusive, mainly due statistically underpowered conclusions. A limited number have focused on deaf people's convictions abilities. This study compared a large sample profoundly subjects (n = 74)...

Paranasal computed tomography (CT) has become the investigation method of choice to confirm or exclude diagnosis chronic rhinosinusitis (CRS) on basis its ability deliver objective data regarding presence inflamed mucosa polyps.The aim study was assess reliability CT scan findings among untreated CRS patients without polyps in a nasal endoscopy.Among with clinically demonstrated considered for surgery, 93 subjects who had 2 scans performed at different time points diagnostic process were...

Background: The development of the global digit-in-noise test requires optimization each language version on a group normal-hearing native-speakers. An alternative solution may be an adaptive during ongoing tests in subjects with unknown hearing impairments. objective research was to compare results between these groups. Methods: Digit triplets consisting three pseudo-randomly selected digits were presented speech-shaped noise at various signal-to-noise ratios (SNRs), according protocol...

Abstract Background The observation of tympanic membrane displacement (TMD) opens up the possibility indirect intracranial pressure (ICP) estimation. In this study, we applied a phase-based video motion magnification (VMM) algorithm to reveal spontaneous pulse TMD waveforms (spTMD) and compare them with invasively measured ICP in patients pathologies. Methods Nine adults (six traumatic brain injury three aneurysmal subarachnoid haemorrhage; median age 44 (29–53) years admitted intensive care...

The objective of this response is to

To develop a methodologically uniform digits-in-noise (DIN) test in 17 different languages.

Laser Doppler vibrometry (LDV) is an essential tool in assessing by evaluating ossicle vibrations. It used fundamental research to understand hearing physiology better and develop new surgical techniques implants. also helpful for the intraoperative assessment evaluation of postoperative treatment results. Traditional volumetric LDVs require access a straight line test object, which challenging due structure middle ear way auditory ossicles are accessible. Here, we demonstrate usage...

Significance: Measurements of auditory ossicles displacement are commonly carried out by means laser-Doppler vibrometry (LDV), which is considered to be a gold standard. The limitation the LDV method, especially for in vivo measurements, necessity expose an object straight line laser beam operating from distance. An alternative this approach use handheld laser-fiber probe (HLFVP) with curved tip. Aim: We evaluate feasibility HLFVP tip measuring sound-induced ossicles. Approach: A vibrometer...

Introduction The effect of SARS-CoV-2 on hearing has not been thoroughly examined. Factors limiting tests in COVID-19 patients are hygiene requirements and the need to use specialized equipment. objective study was assess changes thresholds between diagnosis convalescence using a mobile app. Material methods Patients with mild moderate symptoms, who were isolating at home enrolled 1 September 2020 31 January 2021. Subjects answered an online medical survey self-assessed Hearing...
