Ms. Daisy E is currently working as an Assistant Professor in Physics at the Sri Ramachandra Faculty of Audiology and Speech Language Pathology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai, India. She is an academician since 2003.
She completed her undergraduate studies with distinction and received university rank after the completion of postgraduate programme. She also completed her M.Phil., in Physics with distinction. She is currently doing her doctoral studies at the University of Madras.
She began her teaching career at Arts and Science College before moving on to SRIHER. She teaches many courses including acoustics, electronics, medical electronics, bio-physics, noise exposure and its effects, medical physics and instrumentation for paramedical students across the university. She has been in a teaching profession for about two decades. She created an electronics & optics laboratory for allied health sciences and optometry course. She guided many undergraduate student projects as part of the Chancellor Summer Research Fellowship. She developed the paediatric hearing assessment tool for clinical use referred to as Conventional Visual Reinforcement Audiometry.
As a mentorship programme coordinator, she organises mentorship meetings with students and faculty in her specified domain. She has been a class coordinator in the FASLP for about 18 years.
She coordinated and organised awareness programmes in collaboration with the Office of the State Commissioner for the Differently Abled (Govt. of Tamilnadu) on “Prevention of Noise Pollution and Control” for traffic policemen, NGO’s, school students, school teachers, AC plant workers, nurses, bus drivers, and social workers across different districts of Tamilnadu
Her area of Interest includes electronics and acoustics with the focus on noise pollution in the environment. She conducted studies to investigate the impact of noise on the hearing health of drivers, grinding mill workers and students who listen to music on personal listening devices.

Noise pollution presents a substantial challenge, particularly in urban locations. As the population in metropolitan areas continues to grow, the transportation sector has experienced substantial growth to meet the increasing demand. However, the detrimental effects of noise pollution, particularly traffic noise, on long-term health in developing countries are not yet well understood. This research investigates the personalized noise exposure levels and auditory health of a specific group of individuals, in particular the auto drivers. The study involved 121 healthy professional drivers who were recruited from urban areas in Chennai and participated in a cross-sectional study. Drivers in these studies were subjected to personalized noise exposure measurements using an instrument called noise dosimeter. According to the findings, the auto drivers operating in Chennai metropolitan were exposed to noise levels that exceeded the recommended limits established by Indian and other organizations. The study utilized semi-structured interviews with drivers to assess the potential impact of noise on their auditory and non-auditory health outcomes. The results of these studies demonstrated that individuals of all age groups were significantly affected by both auditory and non-auditory health effects. Furthermore, these studies revealed an existence of significant association between exposure to road traffic noise and an increased risk of hypertension and diabetes in auto-drivers. The hearing thresholds and auditory health of 121 drivers were assessed through pure-tone audiometry testing, extended high frequency testing, and distortion product oto-acoustic testing. These studies revealed that the decline in auditory health among the driver population was influenced by three factors: years of driving experience, age of drivers, and exposure levels. The prevalence and incidence of hypertension were observed in the driver population, and no correlation was established between hypertension and auditory characteristics in these studies. These research findings provide a significant contribution to the existing pool of knowledge regarding the impact of noise levels on auditory health and other physiological consequences among drivers. This data is important for investigating the effects of prolonged noise exposure on the health of individuals who are regularly exposed to high levels of noise.
