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.

Discussions on among allies for govt formation: Ajit Pawar

Updated: Nov 29, 2024

Ajit Pawar

Mumbai: Deputy Chief Minister and NCP head Ajit Pawar on Monday said discussions were underway among the Mahayuti partners to finalise a formula for the new government formation in the state.


Speaking to reporters at Karad in Satara district, Pawar also acknowledged the contribution of the government's Ladki Bahin scheme, which provides financial assistance to women, in the Mahayuti's victory in the just-concluded state assembly polls.


The NCP leader also assured that the alliance was working cohesively following its resounding victory in the state assembly elections.


Pawar paid tributes to Maharashtra's first chief minister Yashwantrao Chavan at his memorial in Karad on his death anniversary.


In the state poll results declared on Saturday, the Mahayuti, which comprises the BJP, Chief Minister Eknath Shinde's Shiv Sena and Ajit Pawar-led NCP, bagged an impressive 230 of the 288 assembly seats.


The focus has been on BJP leader and Deputy Chief Minister Devendra Fadnavis, who is being seen as a strong contender to occupy the top post for the third time, as his party bagged 132 of the 149 seats it contested in the state.


Notably, Maharashtra minister and Shiv Sena leader Deepak Kesarkar has said his party legislators feel Eknath Shinde should continue as the chief minister of the state, where the ruling Mahayuti scored a landslide victory in the assembly polls.


Ajit Pawar said, "We will decide what formula to work out on the cabinet formation among the three parties."


Reflecting on the elections, he acknowledged the contribution of the Ladki Bahin scheme in the Mahayuti's win.


"We cannot ignore that Ladki Bahin helped us in this election. We are grateful to them (women voters)," he said.


Defending the scheme, Pawar, who is also the state finance minister, further said, "Had I been opposed to the Ladki Bahin scheme, I would not have presented it in the House. I discussed the scheme with several retired finance officers before finalising it."


Pawar also dismissed concerns raised by some opposition leaders over the Electronic Voting Machines (EVMs), pointing out that polls in states like Punjab, West Bengal and Telangana, governed by their political opponents, have been conducted with the same system.


Commenting on members of same families contesting against each other during the elections, Pawar expressed annoyance over repeated questions on it.


He then asked, "Why was my close nephew fielded? Atram's own daughter was fielded against him, and even Rajendra Shingne faced a similar challenge. I don't want to comment further on this. I have got tired of apologising for fielding my wife against Supriya. Yugendra was in business, then why was he prepared to contest against me?"


In the Baramati assembly seat, Ajit Pawar was pitted against his nephew and NCP (SP) candidate Yugendra Pawar.


In Aheri seat, NCP leader Dharamraobaba Atram's daughter Bhagyashree Atram contested against him on NCP (SP) ticket.
