BACKGROUND According to previous studies, most of the speech recognition disorders in older adults are theresults of deficits in audibility and auditory temporal resolution. In this paper, the effect of ageing on timecompressedspeech and auditory temporal resolution by word recognition in continuous and interrupted noisewas studied. METHODS A(More)
OBJECTIVE There is little information about processing of nonspeech and speech stimuli at the subcortical level in individuals with attention deficit hyperactivity disorder (ADHD). The auditory brainstem response (ABR) provides information about the function of the auditory brainstem pathways. We aim to investigate the subcortical function in neural(More)
INTRODUCTION The aim of this experimental laboratory study was to evaluate the effect of different mixing and placement techniques on compressive strength (CS) of calcium-enriched mixture (CEM) cement. METHODS AND MATERIALS CEM powder was mixed with its liquid either by hand mixing or amalgamator mixing. The mixture was loaded to cylindrical acrylic molds(More)
INTRODUCTION The family of each hearing-impaired child has its own cultural, social, educational, and financial background, and its own special needs. The objectives of our study were to explore the information and support needs of parents of children with severe-to-profound hearing impairment and to investigate the effects of the parents' level of(More)
BACKGROUND The relation between the auditory steady-state response (ASSR) and behavioral audiometric thresholds requires further clarification in the case of adults with auditory neuropathy/auditory dys-synchrony (AN/AD). PURPOSE The aim of this study was to compare pure-tone audiometric threshold (PTAT) and ASSR in adults with AN/AD. STUDY SAMPLE(More)
INTRODUCTION Cochlear implantation can facilitate the development of communication skills in children with profound hearing loss. The objectives of our study were to determine the average ages at suspicion and diagnosis of hearing loss, amplification, intervention, and performing the cochlear implantation and to investigate the effects of the parents' level(More)
BACKGROUND Aging can cause loss of balance, which may lead to physical and psychological problems. As the role of the otolith organs in maintaining postural stability has been emphasized in recent years, the present study investigated the effect of aging on saccular function using cervical vestibular evoked myogenic potentials (cVEMP). METHODS The(More)
INTRODUCTION Preterm birth is a risk factor for a number of conditions that requires comprehensive examination. Our study was designed to investigate the impact of preterm birth on the processing of auditory stimuli and brain structures at the brainstem level at a preschool age. MATERIALS AND METHODS An auditory brainstem response (ABR) test was performed(More)
INTRODUCTION Hearing loss is one of the most common problems in elderly people. Functional side effects of hearing loss are various. Due to the fact that hearing loss is the common impairment in elderly people; the importance of its possible effects on auditory memory is undeniable. This study aims to focus on the hearing loss effects on auditory memory. (More)
Background and Aim: Auditory memory plays an important role in developing language skills and learning. The aim of the present study was to assess auditory verbal memory and learning performance of 18-30 year old healthy adults using the Persian version of the Rey Auditory-Verbal Learning Test (RAVLT). Methods: This descriptive, cross-sectional study was(More)
