Proud moment for Shivaji University researchers

Indian patent for portable sound absorption testing device Kolhapur: Researchers from Shivaji University, Kolhapur, have developed a portable sound absorption testing device that can scientifically assess whether an installed sound system and its acoustic treatment are functioning effectively. The innovation has been granted an Indian patent, marking a first-of-its-kind development in this field, the university said on Thursday. The patented device, named the Portable Sound Absorption Tester, has been developed by senior chemist Dr Kalyanrao Garadkar of Shivaji University, along with Dr Sandeep Sable and Dr Rohant Dhabbe of Jaysingpur College, and Dr Chandrala Jatkar of the D K T E Society’s Textile and Engineering Institute, Ichalkaranji. The device is designed to test the sound absorption capacity of professional acoustic systems used in recording studios, theatres, auditoriums and soundproof chambers. Until now, the effectiveness of such sound-absorbing installations has largely been assessed through experience and trial-and-error after installation. The newly developed portable tester allows for immediate and scientific evaluation of sound absorption performance once the system is installed. Sound-absorbing sheets and panels are widely used in theatres, studios and vocal recording rooms to absorb echo around microphones and create a controlled acoustic environment, enabling cleaner and more professional audio output. The new device can be used to evaluate a wide range of absorbers, including perforated foam, fibre, fabric, membranes, panels and resonant absorbers, helping improve the quality and effectiveness of acoustic materials. Explaining the working of the device, Dr Garadkar said that the human audible frequency range extends from 20 Hz to 20 kHz. The device generates sound waves within this spectrum and projects them onto the acoustic material under test. The sound waves that are not absorbed are detected by a microphone and displayed on the screen in the form of current or voltage readings. This enables users to instantly determine whether the sound absorption system is functioning as intended and make corrective interventions if required. The researchers said the device would also be useful for those engaged in acoustic fabrication and sound absorption research. Apart from being portable and easy to transport, the device is also cost-effective, making it suitable for field applications. The team expressed confidence that it would prove highly useful in the sound system testing sector. Shivaji University’s in-charge Vice-Chancellor Dr Suresh Gosavi and in-charge Pro Vice-Chancellor Dr Jyoti Jadhav congratulated the research team on securing the patent.

A beacon of hope for rural athletes

How Akash Shinde transformed from a shy village boy to a prominent kabaddi player

beacon of hope

Mumbai: In the heart of Nashik's Adgaon village, a young boy Akash Shinde dared to dream big. Little did he know that his journey from playing in the muddy grounds of his town to becoming a PKL winner would inspire a generation of aspiring athletes.


“Initially, when I used to play, I would come home with bruises because Kabaddi was played in the mud,” Akash recalls as he enters his fourth season with the Puneri Paltan. And despite his family's initial concerns, his passion for kabaddi burned bright, fuelled by the unwavering support of his early mentors Sagar Malwade and Vinod Labde.


His path to success was far from smooth. He faced numerous setbacks, failing to make the cut in his first attempts at various levels. “I fell short in my first attempts at all levels. I went for my senior camp for Maharashtra and fell short there too!”


But instead of letting these failures discourage him, Akash used them as stepping stones. “These setbacks kept me determined, and I knew I needed to try harder and with renewed energy to show the world what I could do and achieve.”


His breakthrough came in 2019 at a seniors’ trial in Nashik. This performance opened doors, leading him to play in the Junior Nationals and eventually catching the eye of Yuva Paltan, which is the Puneri Paltan’s academy.


The turning point in Akash’s career came when he represented his college in Beed, earning his first chance to play for Maharashtra. Under the guidance of Anil Jagdale and Kailas Jagdale, his skills flourished. His journey accelerated as he moved from Mahindra & Mahindra to Yuva Paltan, where mentors like Sangram and Ashok helped refine his game.


Akash’s PKL debut with Puneri Paltan in Season 8 was a moment of immense pride, not just for him but for his entire village. “No player from the Nashik region had made it to PKL or even the Maharashtra team, so it was a shock, a pleasant one, for everyone. The entire Nashik district was very happy. It felt really good,” he reminisces.


But it was in Season 9 that he truly announced his arrival, becoming a formidable force on the mat. In the 22 matches that Akash played on the way to his first PKL final, he scored 139 raid points, averaging 6.32 raid point per match.


His performances caught the eye of the national selectors, earning him a spot on the Indian team for the Asian Games. “I received my Team India kit on the 27th of October. I still remember it,” he says.


The crowning glory came in PKL Season 10 when Akash, along with his Puneri Paltan teammates, lifted the coveted trophy. Albeit playing a diminished role, he managed an impressive 56 raid points in the 13 matches he played. “There was only one target then... we had made up our minds that we had to win the title this season, whatever it took,” he shared, reflecting on the team’s collective determination. Now, Akash stands as a beacon of hope for young athletes from rural India. His message to them is clear: “Keep believing in yourselves and your dedication and efforts.” He emphasizes the importance of loyalty, urging young players to stay true to the clubs that nurture them.


As he prepares for PKL Season 11, his journey from the muddy grounds of Adgaon to the bright lights of Pro Kabaddi serves as a testament to the power of dreams, determination, and unwavering support.
