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.

The friendship files

Love for gym and films brought Morea, Pancholi, Aaditya together

Morea, Pancholi, Aaditya

Mumbai: Otherwise poles apart, the trio – Aaditya Thackeray, Dino Morea and Sooraj Pancholi – have two things in common, passion for gym and cinema. This passion brought them together and created a strong bonding among them.


Aaditya has always enjoyed the company of film stars since many of them used to visit his grandfather the late Balasaheb Thackeray at their Bandra residence, Matoshree. Aaditya developed friendship with Morea during one of such meetings when he was a teenager. The friendship grew over the years irrespective of 20 years of gap in their age.


In 2016, when Morea opened an open-air gym in Marine Drive, Aaditya was the one who had inaugurated it along with actor Jacqueline Fernandez. Several pics of the duo posing together dating back to 2014 can also be found online. Aaditya is reportedly a regular visitor at Morea’s house in Bandra on almost each of his private celebrations.


Their friendship is in spotlight again since Satish Salian, the father of deceased Disha Salian, has named them as prime accused in her death case in a petition filed in the Bombay High Court on Wednesday. Salian has demanded that the trio should be probed for their role in his daughter’s “gang-rape and murder”.


The names of Morea, Pancholi and Aaditya began doing the rounds on various social media platforms right after Disha Salian’s death on June 8, 2020. In hush hush tones, their friendship became the talk of the town. People started adding two and two together. Salian used to work as an executive with a company which managed Rajput’s Public Relations. Salian and Rajput had a professional connection and Morea, Pancholi and Aaditya had a personal connection.


Salian has alleged that the trio has attended a ‘party’ at Disha’s Malad house where she died under mysterious circumstances. Salian believes that the trio are eye witnesses to what happened on that fateful night and there should be a thorough investigation into their role in covering up Disha’s “murder” as a “suicide”.


When asked about his friendship with Morea and Aaditya, Pancholi had told a TV news channel in 2020, “Dino is a friend of mine, whom I meet at the gym sometimes. It has been a long time since I have met him. Aaditya Thackeray sir, I have no connection with. I have never interacted with him.” Sooraj’s ex-girlfriend Jiah Khan had committed suicide in 2013,
