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.

Supreme Court junks plea of woman claiming possession of iconic Red Fort

NEW DELHI: The Supreme Court on Monday rejected the plea of a woman, who claimed to be the widow of great-grandson of Mughal emperor Bahadur Shah Zafar-II, seeking possession of the Red Fort here on account of being the legal 'heir'.


A bench comprising Chief Justice Sanjiv Khanna and Justice Sanjay Kumar termed the plea as 'misconceived' and 'meritless' at the outset and refused to entertain the petition filed against the Delhi High Court order.


"The writ petition filed initially was misconceived and meritless. It cannot be entertained," the CJI said.


The bench did not allow the counsel for petitioner Sultana Begum to withdraw the plea.


"The petitioner is the family member of the first freedom fighter of the country," the counsel said.


The CJI said if the arguments are considered then "why only Red Fort then why not forts at Agra, Fatehpuri Sikri etc"


A division bench of the Delhi High Court, on December 13, last year, had dismissed the appeal by Begum against the December 2021 decision of a HC single judge, noting the challenge was filed after a delay of over two-and-a-half years, which could not be condoned.


Begum said she could not file the appeal owing to her bad health and passing away of her daughter.


"We find the said explanation inadequate, considering that the delay is of more than two-and-a-half years. The petition was also dismissed (by the single judge) for being inordinately delayed by several decades.


The application for condonation of delay is dismissed. Consequently, the appeal is also dismissed. It is barred by limitation," the high court had said.

On December 20, 2021, the single judge dismissed Begum's petition seeking possession of the Red Fort taken illegally by the British East India Company, saying there was no justification for the inordinate delay in approaching the court after over 150 years.


The petition claimed the family was deprived of their property by the Britishers after the first war of Independence in 1857, following which the emperor was exiled from the country and possession of the Red Fort was forcefully taken away from the Mughals.


It claimed that Begum was the owner of the Red Fort as she inherited it from her ancestor Bahadur Shah Zafar-II, who died on November 11, 1862 at the age of 82, and the government of India was an illegal occupant of the property.


The petition sought a direction to the Centre to hand over the Red Fort to the petitioner or give adequate compensation.
