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.

Selective Outrage

India’s left-liberal media has long prided itself on being the torchbearer of secularism, dissent and moral rectitude. In the aftermath of ‘Operation Sindoor,’ the precision military strike launched by the Modi government against Pakistan-based terror camps, it has revealed its not a principled commitment to peace or truth, but a disturbing penchant for ideological prejudice, performative sanctimony and selective outrage.


The operation itself was a textbook display of calibrated force and geopolitical prudence. Prime Minister Narendra Modi, often caricatured as ‘authoritarian’ by the ‘liberal’ English-language commentariat, chose patience over provocation. He consulted opposition leaders, held detailed discussions with defence chiefs and took key international stakeholders, notably the United States and Russia, into confidence before authorising limited military action. The symbolism of ‘Operation Sindoor’ was also carefully crafted: a pointed reminder that the attack’s real victims were Hindu women widowed by Pakistan-sponsored militants in Kashmir. The government’s briefings were also strategic and symbolic as two ranking female officers, one of them Muslim, were made the public face of the mission, underlining a new Indian confidence that blends military muscle with democratic pluralism.


But this was unacceptable for India’s entrenched ‘left-liberal’ press, steeped in academic jargon, Western validation and a knee-jerk hostility to anything remotely ‘Hindutva.’ That a Muslim officer briefed the nation on ‘Operation Sindoor’ was branded ‘tokenism’ by such commentators. Others crudely alleged that the April 22 Pahalgam massacre was the logical culmination of reported atrocities against Muslims since Modi came to power in 2014.


The semantic nitpicking over ‘Operation Sindoor’ was maddening. An editor of a prominent magazine dubbed the operation’s name as ‘patriarchal’ and coded in Hindutva tropes. In a bizarre case of moral inversion, sindoor was likened to symbols of ‘honour killings’ and gender oppression, ignoring both its cultural resonance and the cruel reality that these women had lost their husbands in cold blood. For years, India’s ‘secular’ commentariat nurtured a preordained binary: the Congress may be flawed but was at least ‘secular’ while the BJP was an inveterate ‘fascist.’ Thus, the 2002 Gujarat riots are always focused upon but the Congress-backed pogrom of the Sikhs in 1984 is either downplayed or rationalised. Terrorism in Kashmir is tragic, but state retaliation is ‘jingoism.’ A strong Muslim voice in government is ‘tokenism’ but its absence is ‘exclusion.’ Even journalistic rigour is selectively applied. When Pakistan claimed to have downed Indian jets, some Indian outlets rushed to amplify the story before verification, inadvertently echoing enemy propaganda.


Dissent is vital in any democracy. But when its becomes indistinguishable from disdain, when editorial choices are dictated by ideological conformity, then the press becomes a caricature of itself. Ironically, many of these journalists enjoy robust free speech and loudly lament India’s supposed slide into ‘fascism’ from the safety of their X handles. Yet they turn a blind eye to Putin’s repression, Erdogan’s purges or Xi Jinping’s camps. In their eyes, Modi remains the greatest threat to democracy even as they broadcast their outrage freely, without fear of censorship or reprisal. ‘Operation Sindoor’ was a statement of cultural self-confidence. That confidence has rattled those who have spent their careers gatekeeping Indian discourse. Today, their monopoly is over. The people are watching and they no longer believe that the emperor has clothes.
