Posted November 03, 2019 15:10:22A study conducted by researchers at University of Sydney has found that a small amount of ultrasonic sound can help prevent a person from getting bitten by a dog.
The study, published in the Australian and New Zealand Journal of Clinical Investigation, found that people who used a tooth scraper or tooth filling were significantly less likely to get bitten by dogs.
“Our study suggests that people are able to control the risk of getting bitten in their home by using ultrasonic sounds, which we have not been able to prove yet,” Professor Robert Jolliffe, from the University of New South Wales and lead author of the study, told ABC News.
“It was a very small amount that was able to effectively reduce the risk.”
The study involved about 50 people and found that the people who had been using a tooth scraping device were more likely to be bitten by another person.
“They used a very low intensity sound, so it was about a 5-centimetre-low intensity sound.
We found that they were more susceptible to bites from dogs than people who didn’t use a tooth cleaning device,” Professor Jolliffe said.”
The sound was very low and very gentle.
We wanted to find out how we could change the sound frequency and the frequency at which the sound was delivered to prevent the risk for the bite.”
Professor Jollifer noted that the study had not looked at how to avoid bites.
“I think we are really only just beginning to understand the impact of this kind of technology on humans,” she said.
The research also found that some people were more vulnerable to getting bitten than others.
“We found that if you were a very young person or someone with diabetes, it was also a very effective deterrent to getting a bite, and if you had a high-risk condition, you were more at risk,” Professor Burt O’Donnell, from New South Welsh University, said.
Professor O’Connell said that there was a need to understand why the sound could reduce the severity of dog attacks.
“If you’ve got someone who has got a high risk of dog biting, then you’ve already got a problem with a high degree of severity,” he said.
He said that while the study found that one person had a 10 per cent chance of getting a dog bite, there was no evidence that people were less likely or less likely than the other two to be attacked by a human.
“You’d be surprised how many people are actually bitten by their dogs and how they can actually prevent a bite from occurring,” he told ABC Radio Sydney.
Professor Jlliffe said that she and her colleagues had been investigating whether sound could also be used to reduce the number of bites, and that their results were “quite encouraging”.
“This research is exciting, because we are very close to a place where we can actually start to have an impact on this,” she told ABC RN.
“This study demonstrates the effectiveness of ultrasonics in preventing dogs from biting people, so hopefully we can do more research on how to use ultrasonic technologies for other uses.”
