The singer's formant has been found to be an important acoustic characteristic of professional operatic altos, tenors, baritones and basses, while it seems unclear whether or not sopranos possess it. According to Dmitriev & Kiselev (1 979) the JFequencies of the "high singing formant" increases @om lower voices to higher voices. By means of a listening test with synthesised vowel stimuli we exa...

Three hundred and two sailors were exposed by phones in groups of 11-20 men to 2.2 kilocycle/sec (kc) pulses (5 msec rise-fall time) of 37-250 msec pulse duration at 105-120 dB sound pressure level, duty cycle (ontime/total time) from 0.1—100%, and for 5-120 min/session. Permutations were selected to throw direct light on the four stimulus variables and on their interactions as well. Pulse-tone...

OBJECTIVE Previous studies suggest that dysphonic voices are perceived more negatively than typical voices, and it is possible that vocal perception influences academic achievement and comprehension. This study assessed children's subjective ratings and opinions of a typical and dysphonic voice after performing a language comprehension task in background noise. It also explored if subjective ra...

BACKGROUND The interaction between a clinician and a patient who put his problems down to myalgic encephalomyelitis is described. Despite attempting a patient-centred approach, the doctor acted on his own understanding of the meaning of this diagnosis without gaining proper insight into what it meant for the patient. This failure not only led to damaged rapport, it may have contributed to delay...

Anecdotal reports of fatigue after sustained speech-processing demands are common among adults with hearing loss; however, systematic research examining hearing loss-related fatigue is limited, particularly with regard to fatigue among children with hearing loss (CHL). Many audiologists, educators, and parents have long suspected that CHL experience stress and fatigue as a result of the difficu...

Background: Most hemodialysis patients may experience physiological and psychological stress. Exposure to nature has been reported reduce stress levels improve immune function. This study aimed investigate effects of integrated indirect forest on chronic renal failure undergoing hemodialysis. Methods: As a quasi-experiment, this employed nonequivalent control group, repeated measurements, non-s...

Fibromyalgia (FMS) is a chronic, painful disorder often associated with measurable deficiencies in attention. Since EEG biofeedback (EEG-BF) has been used successfully to treat attention problems, we reasoned that this modality might be helpful in the treatment of attention problems in FMS. We also speculated that improvement in central nervous system (CNS) function might be accompanied by impr...
