pistachio nuts are the major non-oil export agricultural commodity in iran. the existence of empty shells among the shells with kernels reduces the quality of the nuts and, consequently, their market value. in pistachio processing plants, empty shells are generally separated from shells with kernels by the flotation method. but this method is not precise and may encourage the growth of fungi in...

background and aim: spatial hearing is one of the most important functions of binaural hearing processing that is based on detection of fine interaural time and interaural intensity difference. spatial hearing is beyond auditory localization and lateralization. it helps auditory scene analysis and target stream segregation from other simultaneous sound sources. this function is important in spe...

background and aim: this study investigated whether objective temporal processing paradigms including voice-onset-time, speech-in-noise, and amplitude modulated-broad-band noise (am-bbn) are sensitive to disrupted temporal processing in elderly listeners with normal hearing (age-related-temporal processing deficit). methods: we evaluated 15 adults aged 64–80 years using behavioural measures of ...

The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

a b s t r a c t introduction:we investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. methods: the verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...

in this study, using sound created by wheat grain passing through a pipe, wheat flow rate was measured. the developed device consists of a hopper, metering device, sound sensor, delivery tube, dc motor and power supply. several wheat mass flow rates were tested and the sound signal created by the passage of the grain through the discharge tube was measured and transferred to a computer using da...
