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.

Those helping BJP are Maharashtra’s enemies: Uddhav

Kolhapur: Shiv Sena (UBT) president Uddhav Thackeray on Tuesday hit the campaign trail and pitched the November 20 assembly polls as a battle between those who love Maharashtra and the ones who betray it as he reflected on the 2022 split in the party.


Thackeray hit out at his former ally BJP and its partners, saying those helping the national party are “enemies” of Maharashtra as he made a slew of promises to voters, including building a temple of Chhatrapati Shivaji Maharaj in every district if the opposition Maha Vikas Aghadi comes to power.


Addressing his first rally of the 2024 assembly polls in Radhanagri in Kolhapur district -- the constituency of Prakash Abitkar, one of the 40 Shiv Sena MLAs who rebelled against his leadership -- he said those who love the state are aligned with the opposition MVA which comprises the Shiv Sena (UBT), Congress and NCP (SP).


Those helping the BJP, a constituent of the ruling Mahayuti bloc, are “enemies” of Maharashtra, Thackeray remarked.


Further attacking his one-time ally, the former CM accused the BJP of “selling” Maharashtra to Gujarat, where it is in power.


Thackeray claimed his government was toppled in June 2022 because he did not allow the BJP to harm Maharashtra and said not a single industrial project moved out of the state when the MVA was in office under his leadership.


“(Maharashtra assembly poll) is a fight between those who love the state and the ones who betray it,” Thackeray told the gathering.


The Shiv Sena (UBT) president started his speech with the sentence ‘Jamlelya Majhya Tamam Maharashtra Premi Bandhavanu, Matanu ani Baghinino’ (My Maharashtra loving brothers, mothers and sisters), seeking to position the electoral battle as a fight between “the ones who love the state and those who work against it”.


In his campaign speeches during the Lok Sabha polls in April-May, he would start his address with the sentence ‘My Maharashtra loving brothers, mothers and sisters’. It was contrary to his regular Hindutva-rooted ‘My Hindu brothers, mothers and sisters’ opening remarks at rallies, perhaps reflecting his alignment with the Congress and the NCP (SP) which project themselves as “secular”.


Referring to petitions filed by his party in the Supreme Court seeking disqualifications of rebel Sena MLAs, Thackeray emphasised he has still not got justice from the top judiciary and hence has come to people’s court for justice.


“I am not fighting for myself, but for you and Maharashtra,” the former CM insisted.

He accused the BJP of trying to divide people on the basis of religion and castes for the sake of power. Attacking the state’s Eknath Shinde-led dispensation, which assumed office after the fall of the MVA administration, Thackeray alleged the government works on “commission”.


Talking about the Mahayuti government’s flagship scheme for poor women, Mukhyamantri Majhi Ladki Bahin Yojana, Thackeray said police were not even ready to register the complaint of the mother of the girl who was allegedly sexually assaulted at a school in Badlapur in Thane district in August.


He said while the government is implementing the Ladki Bahin Yojana, under which underprivileged women are provided a monthly stipend of Rs 1,500, the inflation is spiralling, making essential commodities costly for common citizens.


Thackeray promised that if the MVA comes to power, every district in Maharashtra will have a temple of Chhatrapati Shivaji Maharaj. The former CM said if possible, he will also build a temple dedicated to the 17th century Maratha warrior king in Surat in present-day Gujarat, a city linked to Shivaji Maharaj’s military campaign.


He assured that after the MVA comes to power, rates of essential food items like rice, pulses, oil and sugar will be stabilized. Thackeray said currently education for female students is free in the state, but a MVA government will extend this benefit to male pupils, too.
