This study evaluated functional benefits from bilateral stimulation in 20 children ages 4-14, 10 use two CIs and 10 use one CI and one HA. Localization acuity was measured with the minimum audible angle (MAA). Speech intelligibility was measured in quiet, and in the presence of 2-talker competing speech using the CRISP forced-choice test. Results show that both groups perform similarly when spe...

IMPORTANCE Middle ear disease is the primary cause of hearing loss in children and has a significant impact on language development and academic performance. Multiple prognostic factors have previously been examined, but there is little published data regarding frequency-specific hearing outcomes. OBJECTIVE To examine the relationship between type I tympanoplasty in a pediatric population and...

The reception of speech transmitted through an acoustic channel such as the ocean is limited by multipath "time-smearing." The purpose of this study was to obtain a quantitative measure of the effects of such timesmearing on speech intelligibility. A linear, time-invariant channel was used as a model of the ocean. The impulse response of this channel was a sample of band-limited Gaussian noise....

OBJECTIVES Otoplasty is a commonly performed surgical procedure that restores the ideal position of the pinna. Although the pinna is a well-recognized component of the auditory apparatus, no studies have assessed the audiological effects of this procedure. We sought to quantify the impact of pinna repositioning on speech intelligibility and reception. METHODS Eighteen adults with normal heari...

The speech intelligibility for different configurations of a target signal (speech) and masker (babble noise) in a horizontal and a median plane was investigated. The sources were placed at the front, in the back or in the right hand side (at different angular configurations) of a dummy head. The speech signals were presented to listeners via headphones at different signal-to-noise ratios (SNR)...

Introduction: There are a few studies that compare the outcomes between primary and revision tympanoplasties. The purpose of the present study was to compare the results of type I tympanoplasty (i.e., synonymous to myringoplasty) and revision myringoplasty based on the closure of tympanic membrane perforation and hearing improvement. Materials and Methods: Thisprospective single-blind study was...

Children with severe hearing loss most likely receive the greatest benefit from a cochlear implant (CI) when implanted at less than 2 years of age. Children with a hearing loss may also benefit greater from binaural sensory stimulation. Four children who received their first CI under 12 months of age were included in this study. Effects on auditory development were determined using the German L...

OBJECTIVE To investigate the effect of injecting the methylprednisolone in the ear for the sudden deafness and the improvement of speech discrimination test. METHODS 50 inpatients with a sudden hearing loss were recruited. Inject the methylprednisolone in the subperiosteal of the ear which is 0.5 cm distance to the ear ditch every three days. Methylprednisolone was placed for fifteen days. Si...

Although great strides have been made in the development of automatic speech recognition (ASR) systems, the communication performance achievable with the output of current real-time speech recognition systems would be extremely poor relative to normal speech reception. An alternate application of ASR technology to aid the hearing impaired would derive cues from the acoustical speech signal that...

Down syndrome (DS) individuals are prone to auditory processing difficulties in a variety of audiological, short-term memory, and language tasks. The present study explored: (a) the hearing capabilities of DS adolescents and young adults relative to a sample of non-DS mentally handicapped (MH) individuals, and (b) the relationship between hearing ability and performance on several cognitive tas...
