The monkey repellent ultrasound machine that was fixed on Friday on trial basis at the pharmacy department in Panjab University is very ‘effective’. The only catch is that it is affecting humans more than the simians!
Fearing that the machine may get stolen if installed in the open, the PU authorities fixed it inside the building near the superintendent’s office. Now, the officials are complaining of discomfort due to the powerful vibrations the machine emanates.
The machine emits highintensity ultrasonic sound waves of 20-50 kHz frequency, causing a pressure of nearly 110130 decibel, making the monkeys uncomfortable and they don’t enter the radiated areas.
Talking to HT, Prof Bhupinder Singh Bhoop, chairman of University Institute of Pharmaceutical Sciences, said, “I was in the department for a short period on Friday. The staff has complained of discomfort due to the vibrations. I will see on Monday where it could be shifted so that humans don’t suffer.”
If the machine is found effective, the varsity will purchase more such devices. Before pharmacy department, the machine was installed in hostel number 7.
The PU had taken the decision to buy such monkey repellant machines in a meeting on April 17. Besides, the varsity had also decided to take assistance of Chandigarh administration to help catch monkeys on the campus.
Monkeys can be found roaming freely all over the campus, posing a threat to the students and the staff.
At present, there are a total of 18 hostels on the campus, eight for boys and nine for girls, and one working women’s hostel, accommodating about 7,000 students. There had been instances of students getting injured in monkey attacks. The university had hired three langurs to chase away the monkeys. For their services, the university was paying Rs 6,000 on each langur per month.
The audit department had raised objections on money being spent on hiring langurs, saying that such an expenditure incurred by the varsity was not tenable, as it was the responsibility of widelife department to take care of monkey menace. After that, services of langurs were discontinued.
