An Application for Screening Gradual-Onset Age-Related Hearing Loss  [PDF]
Wayne M. Garrison, Joseph H. Bochner
Health (Health) , 2017, DOI: 10.4236/health.2017.94051
Abstract:
Objective: Less than 15% of adults in the USA over age 70 receive hearing screening; less than 20% of adults with hearing loss receive any form of treatment. Reasons vary, but affordability and accessibility are major barriers to intervention and treatment. This study provides data supporting a new adult hearing screening measure (NSRT) that is self-administered, easy to use and focused on difficulties experienced in everyday speech communication. Methods: The NSRT test materials are sentence-length utterances containing phonetic contrasts. The test requires respondents to determine whether sentences printed on a computer monitor are the same/different from sentences delivered as auditory stimuli through the computer sound card. The test is administered in quiet and +5 dB SNR background noise. Study participants were 120 adults aged 18 - 88 years. Results: Data obtained from the NSRT testing experience are used to construct a pseudo audiogram. When the predicted hearing thresholds were compared with conventional, clinical puretone measures, the sensitivity and specificity of the NSRT screening measure were 95% and 87%, respectively; diagnostic accuracy was 91%. Conclusions: The NSRT can identify individuals with hearing loss through a simple screening process grounded in standards set by the American Speech-Language-Hearing Association. The NSRT is suitable for administration in clinical and nonclinical settings.

Abstract: Objective: Determine the etiologies and their impacts of hearing loss at the patients’ worn hearing aid in the international center of hearing correction in Abidjan (ICHC). Material and Method: The study is of transverse and analytical type realized in the ICHC from July 1999 to June 2010. It concerned the files of patients’ worn hearing aid in the center. The patients worn initially in another center but followed in the ICHC were excluded. Data were collected from medical files of patients and concerned etiologies, age, type, degree of hearing loss as well as the prosthetic gains and the satisfaction. Results: Fifteen etiologies were listed with in first three rows the meningitis (17.9%) the presbyacusis (17.5%) and chronic otitis media (12.1%). The degrees of hearing loss in the seven etiologies most frequent were severe and profound in 87.6% of cases to the right and 82.8% to the left. The prosthetic pure tonal gain was significant in case of sound trauma and sudden hearing loss. The prosthetic speech reception threshold gain was only significant in case of presbyacusis and sudden hearing loss. The satisfaction of hearing aids was significant in case of presbyacusis, sudden hearing loss and the sound trauma. Conclusion: The main clauses etiologies were the meningitis and the presbyacusis. The tonal and speech prosthetic gain were significant in case of sudden hearing loss.

Abstract: Hearing loss in children constitutes a considerable handicap because it is an invisible disability and compromises optimal development and personal achievement of a child. The period from birth to 5 years of life is critical for the development of speech and language; therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in infants and children. Cochlear implants are the treatment of choice for patients with severe to profound sensorineural hearing loss. The goal of the present study was to investigate the different hearing impairment etiologies of patients implanted in cochlear implant program. The hospital based interventional study was conducted in the Department of Otorhinolaryngology, SMS Medical College, Jaipur from July 2011 to Dec. 2013. Present study included 60 prelingually deafened patients who attended ENT OPD and underwent cochlear implant. The most common cause of deafness in our study was acquired (56.66%), which predominantly included perinatal risk factors (64.70%), followed by prenatal risk factors (41.17%). The second common cause was hereditary (26.66%), followed by unknown (16.66%). Infection and ototoxic drug history were the most common risk factors in prenatal and postnatal group. The most common perinatal cause was low birth weight and prematurity.
