Shhh!
New York City is cracking down on noise: New cams to catch loud drivers …
Times / 06 Dec 2023
Extract :
New York City is combating
excessive noise with the use of noise cameras
These cameras are activated when loud sounds above 85 decibels are detected and are being used to ticket drivers who
violate noise regulations
The city has purchased nine
additional cameras and plans to install at least five cameras per borough.
The new technology functions
"much like a speeding camera," The cameras are always on but they start recording
only when loud sounds are detected.
Violations cost
offenders between $800 and $2,500.( Rs 66,400
- 207,500 )
Since then, the city has purchased
nine additional cameras at a cost of roughly $35,000 each.( Rs 29 Lakh )
And on Wednesday, the
City Council is expected to vote on a bill that would establish a citywide
noise camera programme with the aim of installing at least five cameras per
borough.
My Take :
Dear Shri
Chahal
[
Commissioner – Mumbai Municipal Corporation ]
I think NOISE POLLUTION in Mumbai is worse than in New York .
Obviously, even with its FIXED DEPOSITS , running into Rs 70,000 CRORE , BMC cannot afford to implement those New
York type cameras costing Rs 29 lakh each
I believe BMC is already in the process of installing thousands of CCTV
cameras on the 1600 Km streets / roads of Mumbai
I urge you to challenge our geek Startups to come up with a cheaper /
simpler / elegant , solution to this pollution , improving upon my suggestion in following blog /

Loudspeaker
Politics ? How about Loudspeaker Techniques ? …………. 28 Apr 2022
Extract :
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
Dear
Shri Bhupender Yadavji – Shri Ashwini Kumar Choubeyji
( Ministers for Environment )

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
