Patients who use the Ineraid cochlear implant were tested in four experiments with materials which assessed frequency discrimination and speech understanding. In each experiment both frequency discrimination and speech recognition varied among patients. Correlations between the two measures were significant and ranged from 0.60 to 0.83. Most generally, frequency discrimination was better in the...

A parametric conversion of speech individuality is proposed based on STRAIGHT speech representation. STRAIGHT speech analysis-synthesis can produce high quality speech for various kinds of transformations by using 1) pitch synchronous windowing, 2) time-frequency spectrum interpolating and 3) randomized all-pass filtering for shaping phase spectrum. In order to utilize the smoothness of STRAIGH...

Autism Spectrum Disorder (ASD), characterized by impaired communication skills and repetitive behaviors, can also result in differences in sensory perception. Individuals with ASD often perform normally in simple auditory tasks but poorly compared to typically developed (TD) individuals on complex auditory tasks like discriminating speech from complex background noise. A common trait of individ...

PURPOSE To assess the benefits of cochlear implantation in the elderly. PATIENTS AND METHODS A retrospective analysis of 31 postlingually deafened elderly (≥60 years of age) with unilateral cochlear implants was conducted. Audiological testing included preoperative and postoperative pure-tone audiometry and a monosyllabic word recognition test presented from recorded material in free field. S...

Introduction: Sudden sensorineural hearing loss (SSNHL) is a true emergency that must be diagnosed and treated immediately. The purpose of this study is to compare the efficacy of treatment with intratympanic dexamethasone plus oral prednisolone daily or every other day with that of treatment with oral prednisolone alone. Materials and Methods: Sixty-three patients with SSNHL that had been p...

It was a population based cross sectional study done with the objective of comparing some parameters (attitude & practice) of gender discrimination (GD) in rural and urban areas of Ahmedabad district. A population of 963 (446 urban & 517 rural) showed alarmingly adverse sex ratio (SR) as low as 562 among urban preschoolers. GD was prevalent in both study areas but manifested differently. Prefer...

Different speech sounds evoke unique patterns of activity in primary auditory cortex (A1). Behavioral discrimination by rats is well correlated with the distinctness of the A1 patterns evoked by individual consonants, but only when precise spike timing is preserved. In this study we recorded the speech-evoked responses in the primary, anterior, ventral, and posterior auditory fields of the rat ...

Stable isotope measurements are increasingly being used to gain insights into the nutritional ecology of many wildlife species and their role in ecosystem structure and function. Such studies require estimations of trophic discrimination factors (i.e. differences in the isotopic ratio between the consumer and its diet). Although trophic discrimination factors are tissue- and species-specific, r...

A chiral N,N'-dioxide-Ni(II) complex was found to exhibit highly enantioselective fluorescent recognition of chiral amines and amino alcohols. It can be used to determine their concentration and ee value. Using a 96-well plate, high-throughput screening for enantiomer discrimination was accomplished.
