Objective : To assess neonates and children suffering from meningitis , during the critical and recovery periods , using ABR , EOAE and Behavioral Audiometry.
Method and Material: 40 neonates to 12-year-old children were assessed. Using ABR test, the hearing of these cases was evaluated during the critical period-that is , 24-72 hours following the diagnosis. This test was repeated when patients recovered from meningitis-that is 24 hours before discharge (recovery period) Hearing function , again , was assessed 7-14 days following discharge through Immittance Audiometry, Behavioral Audiometry (PTA , SF and BOA). And EOAE (TEOAE and DPOAE) tests procedures.Findings: During the critical period , ABR test revealed normal hearing in 35 patients (87.5%) and severe to profound sensorineural hearing loss (unilateral and bilateral) in 5 patients (12.5%-girl=4, boy=1). The same result were obtained in re-evaluation in the recovery period. On the other hand , 7-14 days after of discharge , Immittance Audiometry and Behavioral Audiometry (including PTA , S.F and BOA tests), confirmed the mentioned results (cross - gcheck). EOAE test (DPOAE and TEOAE) in 35 normal hearing patients (according to ABR test) , showed normal cochlear function. 2 out of 5 cases suffering from severe to profound sensorineural hearing loss revealed normal cochlear function. According to EOAE results , abnormal cochlear function was evident in 3 patients.
Conclusion: ABR , EOAE tests , and Behavioral Audiometry in children meningitis during the critical period and recovery period can be used to diagnose any degree of hearing loss with a high level accuracy. The results of persent study is confirmed by previous investigations.

Background and Aim: Hearing loss is one of the most prevalent chronic diseases in the elderly using a hearing aid to alleviate auditory impairment can positively affect their quality of life. This research aimed to determine the level of satisfaction concerning hearing aids in elderly people with hearing impairment based on the type and degree of hearing loss.

Methods: An analytic cross-sectional research design was used the sample included 40 elderly people who used hearing aids. According to the World Health Organization (WHO) age classification, participants were divided into two age groups: 65-74 years (n=20) and 75-90 years (n=20). Satisfaction levels were assessed using a standard satisfaction with amplification in daily life (SADL) questionnaire.

Results: Satisfaction levels in the 65-74 age group were significantly higher than that in the 75-90 age group (p=0.02). Participants with mixed hearing loss revealed higher satisfaction levels than participants with sensorineural hearing loss (p=0.02). On the negative effects dimension, participants with severe hearing loss exhibited significantly higher satisfaction levels than participants with moderate or moderate to severe hearing loss (p=0.01).

Conclusion: Total satisfaction mean scores were relatively high in the elderly participants . Negative features could be reduced via careful consultation regarding the aids’ amplifying capabilities and limitations in groups with moderate or moderate to severe hearing loss.
