Background: According to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. In this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. Methods: A time-compressed speech test (TCST) w...

PURPOSE Hyperbaric oxygen therapy has shown efficacies in the treatment of a number of diseases. The goal of this study was to develop a rodent hyperbaric chamber for MRI studies and to investigate the effects of hyperbaric air and hyperbaric oxygen on local magnetic field (B0 ) and MRI relaxation parameters in the rat brain. METHODS A hyperbaric chamber, constructed to fit inside an animal M...

background and aim: foundations and mechanisms of auditory scene analysis (asa) including segregation and integration were especially reviewed in the study. i focused on the related studies using event-related potentials (erps). recent findings: publications on asa using erps from 1971 to 2014 indicate neural mechanisms of asa in central auditory system. conclusion: asa results in recognition o...

the objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. after dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. t...

the purpose of the present study is the comparison of the pattern of language perception in down syndrome (ds) children and typical children. to achieve the objective, nine subjects with ds (whose mental ages were 72-78 months and were drawn from five center of special education in the city of mashhad) and five typical children with the same mental ages were selected through random sampling; an...

The role of emotions in the tourist experience is becoming increasingly important designing experiences to guarantee maximum involvement and satisfaction for tourists/customers. Previous literature has shown how atmosphere (e.g., visual, auditory, olfactory, tactile variables) may influence consumers’ toward proposed experience. However, some offers theatrical performances, theme park...

global warming is one of the major concerns in environmental issues. its effects are being exposed faster than anticipated recently. it causes adverse ecological and socioeconomical effects. the 4th assessment report issued by the u. n.’s intergovernmental panel on climate change (ipcc) states that it is appropriate to define global warming was caused by greenhouse gases due to human activities...

conclusions the analysis of the findings of the present study through considering the defined categories demonstrated that, to modify and correct the turbulent atmosphere-based management, several important measures are required and need to be continually monitored. results the result of data analysis was the theme “turbulent atmosphere-based management,” which consists of five categories as fo...

the main sources of human exposure to trace metals for non-occupationally exposed individualsare inhalation and ingestion. because the absorption rates of the metals by inhalation are significantly higher (up to 50-60%) than those by ingestion (between 3% and 10%), determination of trace metals in ambient air samples is of special interest. the main purpose of this study was to determine fe, zn...
