Tuning fork test11/4/2022 ![]() In the absence of appropriate diagnosis and intervention it can become a lifelong disability with serious consequences on the quality of life and societal integration and participation of the affected persons. Hearing loss is a pervasive global healthcare concern with an estimated 10% of the global population affected to a mild or greater degree. The kaleidoscopic perspective on the audiological instruments enables for a presentation of hearing beyond the passive position it has partaken within especially the field of sound studies and the field of audiology, and it propose hearing as a varied, malleable and indeed complex perceptual auditory state. As this approach has strong ties to the phenomenological research methodology of Martin Heidegger and Maurice Merleau-Ponty, but also to contemporary research methodologies such as media archaeology and object-oriented ontology, the research project evolves as a tuning between manifold methodologies and theoretical positions, which creates different entrances for exploring the history, the epistemic claims and the auditory attention connected to the act of hearing. These sound works propose an alternative methodology for reaching conceptualizations of hearing, where the act of doing, of entering into a practical dialogue with a specific material, forms a way of thinking. The research project departs from the construction of three sound works that stage an obsolete audiometer, a row of imaginary sound therapy instruments and a set of reconstructed hearing horns within an aesthetic setting. By attending to both the discursive frames and the operative means of selected audiological instruments, it exposes how technology tunes the ear, that is how technology lets us hear and how technology frames conceptions of hearing. This thesis sets out to propose a new attention towards the term hearing by exploring the technologies which historically have been used to diagnose, normalize and even optimize the ear. This study revealed the hearing stability of the road-noise affected people of Dhaka city on the basis of a time-distance-intensity complex phenomenon of noise. ![]() Among them 2 persons was hawker and 1 person was shop keeper. We got 3 people (10.34%) whose hearing status decrease permanently for exposing such type of noise for long time. PTA test was performed on 29 people (shop keeper-15 and hawker-14) for assessing the status of hearing. In this paper several measures are proposed to reduce the noise level in this area. We measured the noise pressure level by digital sound level meter (model no: ST-8850) and PTA test was performed by clinical audiometer (model no: AC33). Sound pressure level was measured continuously from 9.00am to 12.00pm and 3.00pm to 6.00pm and it was found that the sound pressure level was remained 75-80dB all over the day. ![]() ![]() Our focus group was hawker and shop keeper. In this paper, the impact of traffic noise on hearing status has described in detail. Our study area was Shahbag in Dhaka city. There are numerous effects on the human environment due to the increase in noise pollution. In the past thirty years, noise in all areas especially in urban areas has been increasing rapidly. Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives. ![]()
