Professor Prasher's academic career at
University College London spans audiology, noise-induced hearing loss,
the health impacts of environmental noise, and biomedical research. He
is the Founding Editor-in-Chief of Noise & Health ---
the leading international journal in its field --- and has edited six
major academic volumes. His work has accumulated over 3,700 citations on
Google Scholar, includes three publications in The Lancet,
and has been featured across BBC television and radio, NBC, the Canadian
Broadcasting Corporation, Deutsche Wella, The Guardian, and
New Scientist.

Public Impact & Media
Professor
Prasher's research has shaped public policy and featured widely in the
media, translating laboratory findings into public health
advocacy.
"
Noise has been the Cinderella form of pollution and people haven't
been aware that it has an impact on their health. The new data provide
the link showing there are earlier deaths because of noise.
All this is happening imperceptibly. Even when you think you are
used to the noise, these physiological changes are still
happening.
Noise & Cardiovascular
Health
Professor
Prasher's research established noise pollution as a major
cardiovascular risk factor --- described by him as the "Cinderella"
form of pollution, long ignored but now recognised as second only to air
pollution in its contribution to premature death. His work demonstrated
that noise acts as a non-specific physiological stressor, triggering the
release of cortisol, adrenaline, and noradrenalin even during sleep,
raising heart rate and blood pressure in ways that accumulate invisibly
over decades.

Even
when people believe they have adapted to noise, physiological stress

causes sleep disturbance and increased mortality risk, particularly in

CONCERTED ACTION ·
2000
NOPHER: Noise
Pollution Health Effects Reduction --- An European Commission Concerted
Action
Prasher D --- Scientist-in-Charge, Institute of Laryngology and
Otology, UCL · Noise & Health, 2000
Led by Professor Prasher as
Scientist-in-Charge at UCL, NOPHER was a European Commission concerted
action designed to reduce the health burden of noise pollution across
Europe --- coordinating research across member states and establishing
the evidence base for EU noise health policy.
RESEARCH PROJECT
NoiseChem: An
European Commission research project on the effects of exposure to noise
and industrial chemicals on hearing and balance
Prasher D et al. --- European Commission funded study
An EU-funded research project investigating
the combined and interactive effects of occupational noise and
industrial chemical exposure on auditory and vestibular function ---
contributing to European noise health policy and workplace safety
standards.

WHO Noise
Environmental Burden on Disease Working Group
Prasher D --- Working Group Member · Convened 2003
Professor Prasher served on the WHO working
group that first quantified the global disease burden of environmental
noise. The group established that noise causes hundreds of thousands of
premature cardiovascular deaths worldwide --- 3,030 in the UK in 2006
alone --- making noise a major public health issue second only to air
pollution. The noise threshold for cardiovascular risk was set at
chronic night-time exposure of 50 decibels, the level of light
traffic.

New strategies for prevention and treatment

Deepak Prasher
Reviewed emerging clinical trial strategies
for 600 million workers in hazardous noise environments --- 25--30
million in Europe alone --- addressing combined risks from noise,
chemicals, and extreme temperatures.

Effect of MRI noise on cochlear
function
Radomskij P, Schmidt MA, Heron CW, Prasher
D
Demonstrated that MRI-generated noise
measurably damages cochlear function via otoacoustic emissions, even
with earplugs fitted --- a finding with direct implications for clinical
practice in radiology.
