UP-like
Drive to Remove Loudspeakers sought in other States /

21,963 loudspeakers have been removed from religious places and volume
regulated at over 42,000 other
Ahead of Eid, loudspeaker politics rages in States / HT / 29 April 2022
Extract :
On April 19, Uttar Pradesh chief minister Yogi Adityanath
told officials to ensure that loudspeakers at
religious places should
not cause “inconvenience” to others, following a row over
Azaan and Hanuman Chalisa recitation on loudspeakers defying the norms.
On April 23, the UP home department issued orders for
removal of loudspeakers from religious places or using them within the pollution control norms and sought
compliance report by April 30.
Till Thursday, home department officials said close to 21,963 loudspeakers were removed across
the state, and volume
control instruments were installed in 42,332 loudspeakers, senior UP government officials said.
“The people have done this of their own free will.
All religious leaders have also welcomed this order,” UP Police Additional
Director General (ADG), Law and Order, Prashant Kumar said on Thursday.
MY TAKE :
Ø For a PERMANENT / LONG-TERM solution
# Pass a law to prohibit the manufacture of HIGH
VOLUME loudspeakers
I believe UP has
prescribed following UPPER LIMITS for Noise Levels :
@ Residential ……….. 55 db
@ Commercial…………65 db
@ Industrial………….. 75 db
Bureau of Indian Standards should lay down SPECIFICATIONS for
loudspeakers which must
apply
All loudspeaker manufacturers will need to display
ISI
their products
# All loudspeakers and all Microphones, to be fitted with internet-
connected SENSORS , capable of
Levels ( decibels ) “ to Central Noise Pollution Control Rooms in each
city
Control Room will have a number of large MONITORING SCREENS
showing location (
loudspeaker
Screen
will display :
Green Dot……………… for loudspeakers within norms ( less than 74 % of
upper limit )
Yellow Dot …………… for “ borderline “ loudspeakers ( between 75 % to
100 % of limit )
Red Dot………………… for loudspeakers exceeding limit ( more than 100
% of upper limit )
Without needing any attention or human intervention, in case of those
loudspeakers
which exceed
get activated to cut-off the electric supply to the culprit microphone and
/ or loudspeaker .
No need
for manual monitoring / persuasion / disputes
Considering that Hon Supreme Court has already ordered installations of
CCTV in all the Police
Agencies, my suggestion will get judicial support
Ø For a TEMPORARY /
SHORT TERM Solution :
How about requesting the MIT team to license their NOISE
CANCELLATION technology described below, to Indian Manufacturers
?
As soon as these devices become commercially available in India, residents
staying near a Masjid / Temple / Church, will buy these to CANCELL out the
loud noise emanating from those blaring loudspeakers.
Having once experienced the BLISS of a QUIET surrounding, device-owners
may even carry it with them ( strapped to their wrists like a Smart Watch
or worn as a pendant hanging from a necklace ), whenever they venture
out on our noisy streets, where loud construction and vehicular noise has
made our lives miserable and produced untold mental stress
State Governments are requested to consider subsidizing the purchase of
such devices

I urge you to consider my suggestion for a Technology Based solution to the
Noise Pollution problem

A novel paper-thin loudspeaker can play music from any surface /
Interesting Engineering / 27 April 2022
Extract :
# Imagine a paper-thin loudspeaker that can turn any surface into an
active
audio source. It would
events.
# Now, MIT engineers have conceived of exactly such a device, according
to a statement published by
to produce sound with minimal distortion while using a fraction of
the energy required by a traditional loudspeaker.
# “It feels remarkable to take what looks like a slender sheet of paper,
attach two clips to it, plug it
and start hearing sounds emanating from it
It can be
power to run it,”
said Vladimir Bulović
the Fariborz Maseeh Chair in Emerging Technology, leader of the
Organic
and Nanostructured
director of MIT.nano, and senior author of the paper.
# The new loudspeaker is the size of a hand and weighs about as much
as a dime, but don't let that
It can generate high-quality sound no matter what surface the film is
bonded to.
# What's more, parties and events are not its only applications. The
loudspeaker could also
provide
clamorous environments, such as an airplane cockpit.
# It would achieve this by generating sounds of the same amplitude but
of
opposite phases r
other out
It's also ideal for use on smart devices where battery life and space are
limited
# Finally, last but not least, the device could have more creative
applications that go beyond sound.
It could use ultrasound to detect where a human is standing in a room
and then shape its
sound waves
It could also be used to create patterns of light for future display
technologies or
stirring chemicals.
# Its applications are many and varied, each as original as the next one.
What could you do with this
