Children can only develop spoken language through consistent exposure to the acoustic cues that comprise speech and language. Until recently, hearing levels from the clinical audiogram were the primary measure used to define typical hearing and the presence or degree of a child's hearing loss. While the clinical audiogram remains an important…

Purpose: Several studies have demonstrated increased auditory thresholds in patients with Parkinson's disease (PD) based on subjective tonal audiometry. However, the pathophysiological mechanisms underlying auditory dysfunction in PD remain elusive. The primary aim of this study was to investigate cochlear and olivocochlear function in PD using…

Hearing levels are threatened by modern life--headsets for music, rock concerts, traffic noises, etc. It is crucial we know our hearing levels so that we can draw attention to potential problems. This exercise requires that students receive a hearing screening for their benefit as well as for making the connection of hearing to listening.

The purpose of this study is to show the changing trends within the population of children who are deaf and hard of hearing in Belgium over the last 12 years. The combination of Universal Newborn Hearing Screening programs, early intervention, and cochlear implants have tremendously influenced the education and support of children who are deaf or…

Purpose: The sensitivity to sinusoidal amplitude modulations (SAMs) is reduced when other modulated maskers are presented simultaneously at a distant frequency (also referred to as "modulation detection interference" [MDI]). This article describes the results of onset differences between masker and target as a parameter. Method: Carrier…

Meeting the audiological management needs of deaf children with learning disabilities is demanding. The study specifically focused on the age at which audiological certainty, the degree, configuration and type of hearing loss, was established in 20 individuals with severe learning disability. Audiological records relating to each individual were…

Purpose: The purpose of this study was to examine children's head orientation relative to the arrival angle of competing signals and the sound source of interest in actual school settings. These data were gathered to provide information relative to the potential for directional benefit. Method: Forty children, 4-17 years of age, with and without…

Assessment of auditory abilities is important in the diagnosis and treatment of children with autism. The aim was to evaluate hearing objectively by using transient evoked otoacoustic emission (TEOAE) and auditory brainstem response (ABR). Tests were performed on 30 children with autism and 15 typically developing children, following otomicroscopy…

Purpose: Some researchers have assessed ear-specific performance of auditory processing ability using speech recognition tasks with normative data based on diotic administration. The present study investigated whether monotic and diotic administrations yield similar results using the Selective Auditory Attention Test. Method: Seventy-two typically…

Forward-masked psychophysical tuning curves were obtained at multiple probe levels from 26 normal-hearing listeners and 24 ears of 21 hearing-impaired listeners with cochlear hearing loss. Results indicated that some cochlear hearing losses influence the sharp tuning capabilities usually associated with outer hair cell function. (Author/JDD)

The paper describes the unexpected finding of evoked otoacoustic emissions from one ear of a subject with severe-to-profound bilateral sensorineural hearing loss. It is suggested that the subject may have a group of surviving outer hair cells in some regions of the left cochlea with corresponding inner hair cell or neural damage. (Author/DB)

The ILO92 was used to determine the level of Distortion Product Otoacoustic Emissions (DPOAEs) at 2f1-f2 for 16 combinations of primary levels in the range of 40 to 80 dB SPL from 40 unimpaired adult ears. An overall increase of DPOAE amplitude with increase in primary level was observed. (Author/CR)

Sensitivity and specificity of static acoustic admittance (SAA) and tympanometric width (TW) were assessed for 116 pediatric patients. A statistically significant change in SAA was observed in immediate repeat measures. No significant change across the two sequential measures was observed for TW, peak pressure, or the estimate of ear canal volume.…

Puretone auditory assessment of 21 adults with severe to profound mental retardation indicated that a bivariate plotting procedure of predicting hearing sensitivity from the acoustic reflexes should be included in an audiological test battery for this population. (CL)
