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.

Pahalgam Attack, Personal Legacy

There are moments that shake us to our core. The recent terrorist attack in Pahalgam, Kashmir, was one such moment — when lives were taken simply for being who they were, for being at the wrong place at a time when no one should have to fear for simply existing.


Among the victims were tourists — families on vacation, children brimming with excitement, couples seeking peace in the valleys. They didn’t know that their journey would end not in memories made, but in a silence that screams of injustice.


And while no words can ever heal the wounds left behind, there is something deeply human about what we feel in such times: helplessness, yes — but also, an urge to do something. To live more consciously. To show up with more purpose. To make sure we’re not forgotten for how we died, but for how we lived.


That’s where the idea of legacy walks in.


We often associate personal branding with social media, business cards, or resumes. But real personal branding goes beyond platforms. It’s about the essence of you — what you stand for, how you make others feel, and the values people remember you for.


In the aftermath of the Pahalgam tragedy, a question echoes louder than ever: If life ended unexpectedly, what story would your life tell?


One of the stories that moved me came from a survivor who said, “He shielded us. He didn’t think twice.” That unnamed man’s act of courage became his personal brand in that moment. Not because he planned it. But because that’s who he was. Someone others could count on.


When your values are so deeply embedded in who you are, they show up even when you don’t realize. That’s personal branding at its purest — unfiltered, uncalculated, unforgettable.


In a world where your name can be Googled before you’re greeted, building your personal brand isn’t just about visibility — it’s about responsibility. About making sure your presence, whether online or offline, becomes a source of trust, comfort, and character.


We don't know how many days we have. But we do know this: every interaction, every act of kindness, every time you offer help or speak up for what's right — it all adds to your story. And that story will live on long after LinkedIn profiles go quiet and Instagram fades out of relevance.


If this tragedy teaches us anything, it is this — let your brand be a reflection of your soul, not your strategy.


Let people remember your generosity, your resilience, your humility. Let your children say, “My parent made people feel safe.” Let your team say, “She stood by me when I was struggling.” Let your friends say, “He showed up, even when it was inconvenient.”


You don’t need a title to have impact. You just need intention.


And if you don’t know where to begin, start with this: Ask yourself how you want to be remembered. Then show up as that person — at work, at home, online, offline.


Because whether or not you realize it, someone is watching. Not to judge. But to be inspired. By your courage. By your consistency. By your quiet strength.


Let that be your brand.


And if you feel lost in figuring out how to express this version of yourself, know that help exists — not to change you, but to reveal the best in you. To help you build a brand that stands even when the world shakes.


We can’t undo what happened. But we can honour it — by becoming more mindful of the legacy we leave behind.


One interaction at a time. One value at a time. One life at a time.
