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.

When the Princess Left Her Fortress…

Updated: Jan 2, 2025

Princess Left Her Fortress

I recently saw a movie, it had this dialogue “teenage girls are psychopaths” and maybe it is right, maybe we are a generation full of messed up kids trying to survive in this deathly jungle we’ve created for ourselves. And this survival gets harder when you’re a 16-year-old that moves into a city way bigger than their own, to ‘step into the world’ with rosy dreams and rosy expectations. I am one of those 16-year-olds, who with very romanticised notions, very naively decided to step into the ‘City of Dreams’: Mumbai.


Mumbai, is probably 10 times the size of my not very humble, but very little town. Moving to Mumbai was my dream since 1st grade, and when that dream manifested, I was on Cloud 9. I thought my life would be perfect, I’d have the perfect group of friends, I’d go to fancy parties, I’d do lots of events in college, I’d be known, I’d be in my ‘Academic Beast’ ‘It Girl’ era and what not; but reality is pretty far from any of that. Back in my town, I was the top of the hierarchy, the Perfect Girl, centre of attention, the Lovely Queen; after moving to Mumbai, my life of the last 13yrs came crashing down on me. I became this introverted, invisible person; the friends’ group or lots of parties definitely did not happen, neither did the academic beast and It girl era.


I came to realise that Mumbai, no matter how pretty, beautiful and picture-worthy, is very harsh and extremely tough. No matter how much anyone says ‘Mumbai embraces all’, the ‘All’ still do feel left out to some extent, when everyone around you is this confident Mumbai Kid and you’re this awkward girl from out of town who knows nothing about the city, its people or its ‘culture’, who’s trying to push through this humongous crowd that’s, without trying very hard, swallowing you down; but standing here, watching this city move past me, I wonder Does Mumbai really not bother about anyone Or Is it just not willing to let you in?


But there’s still something to hang on to, somewhere to belong, isn’t there? When you go back home and you have friends there; Spoiler Alert: you don’t. When I went back home for my first holiday, I realised I didn’t belong there anymore, now I was the Mumbai Girl; 13yrs lost and forgotten, within 3 months. That’s when it hit ‘I’m all alone now’ neither do I belong in Mumbai, neither do I back at home. Trust me, I have never felt more lost in my life.


I’m the kind of people who thrive on attention and external validation, to have that very thing taken from me was very hard to live with. So, I chose to cope by holding on, holding on how? Well, simple tactic, making an indirect statement saying “you excluded me, but I belong in places better than you” how I did that? I held onto my past self, my actions were based on how pretty, fun and ‘happening’ my life was to look on Instagram. I did have fun, not that I didn’t, but most of it was for the eyes of the world and not my own satisfaction [it still is that way, I haven’t gotten any better yet].


Then came my midterms, and I wasn’t as great as I thought I’d be and my extracurriculars weren’t anything major either. That made me realise that I was like any other kid around me here, unlike when I was back home, always the different one, the one that stood out, and suddenly I didn’t anymore, I was ordinary. The realisation hit me, right in the face, hard and strong, that in this huge ocean, I was no whale or shark, just another little fish in the Shoal. My future suddenly became scary, thinking about college and university became terrifying and I just wanted to avoid it all, simply run away [I still do, sometimes] And now, I’m a mess.


But not all of it was bad honestly, Mumbai taught me a lot of things, it humbled me and it helped see: within myself and so many things about myself that I never really knew and were suddenly crystal clear in front of my eyes, as if a very loud noise had been shut down and I could hear clearly again. Back at home, I had this persona designated to me: ‘The Perfect Girl’ and suddenly I didn’t have to be anyone anymore, it was harder that way honestly, to not have a script to follow anymore. I had to discover myself and who I truly was for the first time Ever; I think that’s what I’m doing now, getting to know myself beyond who I was 6 months ago.


Things aren’t any better right now, I don’t think they will be for very long and sometimes moving here may seem like the biggest mistake I’ve ever made, but I wouldn’t want it any other way. So, this new year I have one resolution: I’m going to find who I am, a new persona, a new person, not defined by her past self, past life and this Social Jungle of teenagers she’s surviving in. This new year will be of rediscovery. So, here’s to 2025 and to all of us, whose lives changed because they stepped into the big, bad world out there; let us all be proud of ourselves as this year ends, because leaving our homes and lives behind is not easy and we lived that down: The Shift, the way it hit our egos and shattered our sense of belonging, but we didn’t run away, we strived through it and are surviving to see the light of day.


So, A Very Happy New Year People.

Great write, yes Mumbai is a jungle and you have to fund your true bearings and none towards your destination
