Ahmedabad: King Henry said at Shakespeare ‘Henry V’: “When the explosion of the war blew in our ears, then imitated the action of the tiger …” But in a modern war even the suggestion would often be transmitted in the ears of the army, becoming a Post-Doctoral Fellow IIT -Gandhinagar has developed a device that helps jump communication like tigers above the extraordinary din.
Fusillades noise without stopping is a feature of today’s battle.
It comes from thunder helicopter rotors, racuring relentless machine guns, and destroyed Howl artillery.
But now, Chandan Kumar Jha, a post-doctoral man in Iit-Gandhinagar, has tried to give freedom to Indian soldiers to communicate clearly with their team members even in the war zone, pounding with a conflict echo.
He has made a thinner microphone than the hair and device that accompanies the size of the cellphone that cuts around the interference and allows clear communication.
JHA was recently contacted by Drdo (Organization of Research and Defense Development) to submit an expanded proposal for further support to develop products.
In October 2019, Jha has won the first prize of Rs 5 Lakh, Best 3,000 applicants, for this innovation at Drdo who dared to dream of the contest where he has submitted evidence of concepts.
He was also invited to showcase his work at the Defexpo Exhibition held by the Ministry of Defense in February 2020.
‘The field testing might have increased design and made it more sensitive and user-friendly.
Field testing is expected to take place this year, “said Chandan Kumar Jha who received a PhD in the field of electrical engineering from Iit-Gandhinagar.
According to several websites, soldiers in operations face a series of intense sounds: ranging from 110 dB in a helicopter to 190 dB When the Howitzer is fired.
To put numbers in perspective, normal conversations occur at 60 dB and the level in the moving car is around 70 dB.
“Having a background in the biomedical engineering, my research after my doctoral studies focused on optical fiber technology and its application, “Jha said.” This is often a challenge to convey orders and information clearly when there is so much noise in the battle area.
Conventional microphones cannot selectively take human voice or suppress background noise.
“Thus, the technology depends on the sound directly radiating from the ballot box and reduces the noise of around 120 dB.” The sensor itself is a piece of optical fiber and thinner than human hair and thus has no weight, “Jha said.
