objectives: to evaluate different signal-processing algorithms for tactile identification of environmental sounds in a monitoring aid for the deafblind. two men and three women, sensorineurally deaf or profoundly hearing impaired with experience of vibratory experiments, age 22-36 years. methods: a closed set of 45 representative environmental sounds were processed using two transposing (trha, ...

objectives: conducting field tests of a vibrotactile aid for deaf/deafblind persons for detection, identification and directional perception of environmental sounds. methods: five deaf (3f/2m, 22–36 years) individuals tested the aid separately in a home environment (kitchen) and in a traffic environment. their eyes were blindfolded and they wore a headband and holding a vibrator for sound ident...

Background: Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess the personal and environmental noise level and project the sound map of an Iranian tire manufacturing complex using Surfer V.14 and Noise At Work tools. Materials and Methods: This descriptive study was conducted in the curing hall [including curing, sandblast,...

Plants are influenced inevitably by environmental stresses due to their immobility. Sound waves are one of these environmental factors affecting plants. This study was designed to understand the relationship between sound waves and plant responses that is still low knowledge. For this purpose, Salvia splendens, one of the common plants in urban green spaces, were influenced by sound wa...

Background: Today, the effects of environmental pollution on human life and human needs, which reduces the level of community health caused by traffic noise in large cities, are clearly visible by creating irritation and pathogenic conditions. The aim of this study was to assess the risk of noise pollution resulted from central traffic in Shiraz by analyzing its indicators and related componen...

Environmental sounds are very helpful in understanding environmental situations and in telling the approach of danger, and sound-imitation words (sound-related onomatopoeia) are important expressions to inform such sounds in human communication, especially in Japanese language. In this paper, we design a method to recognize sound-imitation words (SIWs) for environmental sounds. Critical issues ...
