Nonbehavioral tests such as ABR testing, ASSR testing, and OAEs are frequently used to assist in estimating peripheral hearing in infants (ASHA 2004). Although these tests are an important part of the audiology practice, they are, in fact, not tests of hearing. The only true test of hearing is behavioral assessment. ABR, ASSR, and OAE measures provide information about the integrity of specific...

Auditory neuropathy spectrum disorder (ANSD) is a clinical syndrome with hearing loss characterized by measurable otoacoustic emissions (OAEs) and absent or abnormal brain stem evoked response audiometry findings (BERA) (1,2). Routine magnetic resonance imaging (MRI) has been advocated in children with ANSD because cochlear, neural, or central abnormalities are observed in up to 64% of affected...

Background A pilot newborn hearing screening (NHS) program was established at 11 Corporation Maternity Hospitals in Chennai, a city South India, to aid the early detection of loss. Nurses were trained how screen newborns using both otoacoustic emissions (OAEs) and automated auditory brainstem responses (AABRs). The purpose this qualitative study explore nurses’ perceptions NHS challenges they f...

A new technique is proposed for the objective estimate of cochlear tuning, starting from measurements of the delay function of Stimulus Frequency (SF) and Transiently Evoked (TE) Otoacoustic Emissions (OAEs). The technique is quick and reliable, also in not cooperating subjects, while the psychoacoustic tuning measurements are time consuming and based on a large number of assumptions. It is wel...

INTRODUCTION Noise is considered as the most common cause of harmful physical effects in the workplace. A sound that is generated from within the inner ear is known as an otoacoustic emission (OAE). Distortion-product otoacoustic emissions (DPOAEs) assess evoked emission and hearing capacity. The aim of this study was to assess the signal-to-noise ratio in different frequencies and at different...

INTRODUCTION Tegumentary Leishmaniasis (TL) is a neglected, non-contagious, infectious disease, caused by different protozoa species of the Leishmania genus that affects skin and mucous membranes. Meglumine Antimoniate (MA), the first drug of choice for TL treatment in Brazil, has already been associated with cochlear toxicity, which is defined as damages of the cochlea caused by exposure to ch...

Objective: Psoriasis has been accepted as a T-cell mediated systemic disease and inflammation may also cause immune-mediated hearing loss. We aimed to evaluate cochlear function with otoacoustic emission (OAE) measurement in psoriasis patients, whether there is relationship between the duration severity of OAEs. Material Methods: Forty-four patients diagnosed were included study. The control gr...

This review underlines the significant role of early diagnosis and treatment hearing impairment due to bacterial meningitis (BM) in children. BM is a life-threatening neurological condition mostly caused by <i>Streptococcus pneumoniae</i>, <i>Neisseria meningitides</i>, or <i>Haemophilus influenzae</i>. Hearing loss most commonly reported complication BM; inf...

  Background: The possible role of cochlear function in tinnitus generation is still a matter of debate. To assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (UHF) hearing sensitivity, transient evoked otoacoustic emissions (TEOAE) and UHF hearing thresholds were investigated in normal hearing individuals with and withou...

Many metals present in trace concentrations the oceans are sensitive to reduction and oxidation reactions (termed redox-sensitive or RSTMs) can therefore be affected during intervals of expanded oceanic anoxia euxinia (anoxic sulfidic waters). These RSTMs important micronutrients; their availability plays a significant role controlling metabolic pathways ecosystem structure. Understanding links...
