Sound generating human activities is now recognized as a potential driver of environmental changes in marine habitats. Iran has 750 km coastline along the Caspian Sea located in the north and around 2250 km ...

Our field of view is about 120 degrees, we receive much information from outside of the field of view from which it is hard to get the information for the hearing impaired. They have poor crisis perception ability as compared to normal persons. Therefore, we have developed a system to visualize environmental sound in order to assist the hearing impaired. Hearing impaired persons can guess sound...
Aquatic ecosystems are heterogeneous in terms of light and sound distribution. The aim of this study was to investigate the effect of environmental abiotic factors, light and sound stimuli, on Daphnia (Daphnia magna) swimming behaviour. Here, we examined behavioural changes of Daphnia (N=24) in response to light and sound treatments simultaneously. The treatments concerned a 2×2 design with br...
