BACKGROUND Steady state responses (SSRs), between 75 and 110 Hz, evoked by auditory amplitude modulated single or multiple tone stimuli, may be used to estimate objective hearing threshold. METHODS The aim of this study was to compare SSRs and click-evoked auditory brainstem responses (ABRs) in both ears of 20 adults (10 males and 10 females, aged between 24 and 36 years) with normal hearing ...

We have developed a computerized technique for automatic detection and removal of sonomotor waves (SMWs) from auditory brainstem responses (ABRs). Our approach is based on adaptive decomposition using a redundant set of Gaussian and 1-cycle-limited Gabor functions. In order to find optimal parameters and evaluate the efficiency of the methods, simulated data were first used before applying it t...

It has been shown recently that chirp-evoked auditory brainstem responses (ABRs) show better performance than click stimulations, especially at low intensity levels. In this paper we present the development , test, and evaluation of a series of notched-noise embedded frequency specific chirps. ABRs were collected in healthy young control subjects using the developed stimuli. Results of the anal...

OBJECTIVES This study addresses a gap from a South African urban perspective on the knowledge and emotional responses of caregivers with children diagnosed with Down's syndrome (DS). The study is an initial step towards informing health professionals who adopt a biopsychosocial approach, in an effort to improve interventions for both caregivers and children. METHODS A simple descriptive surve...

OBJECTIVES This study is to cross-map telephone nursing consultation documentations with International Classification for Nursing Practice (ICNP; ver. 1.0 concepts). METHODS The narrative telephone nursing consultation documentations of 170 ophthalmology nursing unit patients were analyzed. The nursing statements were examined and cross-mapped with the Korean version of the ICNP ver. 1.0. If ...

There are few systematic comparisons of Etymotic ER-3A insert earphones versus supra-aural earphones in auditory brainstem response (ABR) measurement. We compared ER-3A insert earphones and two types of supra-aural earphones (TDH-39P and TDH-49P) in a group of normal hearing adults. Acoustic analyses revealed spectral and temporal differences among earphones. Behavioral and ABR thresholds to cl...

The click-evoked auditory brainstem response (ABR) is widely used in clinical settings, partly due to its predictability and high test-retest consistency. More recently, the speech-evoked ABR has been used to evaluate subcortical processing of complex signals, allowing for the objective assessment of biological processes underlying auditory function and auditory processing deficits not revealed...

zataria multiflora essential oil possesses immunomodulatory effects and the present study investigatesits effect on immune responses to live newcastle disease (nd) vaccines and faecal shedding period ofvaccine strain virus in chickens. one hundred and eighty chickens from both sexes were divided into 6 equalgroups: group 1: unvaccinated, group 2: vaccinated (b1 vaccine followed by la sota 10 da...

in this paper, a crack localization method for euler-bernoulli beams via an efficient static data based indicator is proposed. the crack in beams is simulated here using a triangular variation in the stiffness. static responses of a beam are obtained by the finite element modeling. in order to reduce the computational cost of damage detection method, the beam deflection is fitted through a poly...

results the analysis of data for c/t snp showed that the cc genotype is more common in the control group than in the group of patients. in contrast, the frequency of tt as a mutant genotype is more frequent in patients than in uninfected people. in addition, results showed a statistically significant relationship between cc, ct, and tt genotypes in sensitive and resistant groups (p value: < 0.0...
