Accuracy and Pitfalls in the Smartphone-Based Audiometry Examination [PDF]

Iranian Journal of Otorhinolaryngology
Introduction: Approximately 466 million people suffer from hearing loss worldwide, with Indonesia ranking fourth in Southeast Asia. However, conventional pure-tone audiometry is not yet available in many areas because of its high cost. Numerous available

User-Operated Audiometry Project (UAud) – Introducing an Automated User-Operated System for Audiometric Testing Into Everyday Clinic Practice

Frontiers in Digital Health, 2021
Hearing loss is the third leading cause of years lived with disability. It is estimated that 430 million people worldwide are affected, and the number of cases is expected to increase in the future. There is therefore increased pressure on hearing health

High Frequency Audiometry [PDF]

Annals of Otology, Rhinology & Laryngology, 1984
After a brief discussion of the past use of and clinical need for high frequency hearing tests, a new technique is described that uses a special electric transduction mode: a 60-kHz carrier frequency is modulated by the desired audiofrequency. The combined signal is applied to the skin over the mastoids by Mylar-covered electrodes.

Hearing Tests Based on Biologically Calibrated Mobile Devices: Comparison With Pure-Tone Audiometry

JMIR mHealth and uHealth, 2018
Background Hearing screening tests based on pure-tone audiometry may be conducted on mobile devices, provided that the devices are specially calibrated for the purpose. Calibration consists of determining the reference sound level and can be performed in

Pure tone audiometry and cerebral pathology in healthy older adults

Journal of Neurology Neurosurgery & Psychiatry, 2019
Background Hearing impairment may be a modifiable risk factor for dementia. However, it is unclear how hearing associates with pathologies relevant to dementia in preclinical populations.

Classification of audiograms in the prevention of noise-induced hearing loss: A clinical perspective

South African Journal of Communication Disorders, 2020
Background: Noise induced hearing loss (NIHL) is a major contributor to disabling hearing loss. Engineering controls are superior to hearing protection devices (HPDs) in prevention of occupational noise induced hearing loss (ONIHL), although the latter ...

NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

Advanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Audiological assessment in patients with chronic obstructive pulmonary disease

The Egyptian Journal of Bronchology, 2017
Background Chronic obstructive pulmonary disease (COPD), as a multisystemic disease, might have an impact on the auditory function. Thus, this study was designed for the audiological assessment of COPD patients to investigate the effect of smoking, and ...

Truncating Variants in RREB1 Cause a Novel RASopathy Syndrome of Congenital Heart Disease, Genitourinary Malformations, and Developmental Delay

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The interstitial 6p microdeletion syndrome is characterized by dysmorphic facies and structural heart, kidney, brain, and musculoskeletal differences. RREB1 haploinsufficiency and consequent abnormal RAS‐MAPK pathway signaling have been proposed as a driver of the disease phenotype; however, apart from a single case report, the phenotype of ...
