Dangers of Ultrasonic Sound in Public Spaces for Health

Dangers of Ultrasonic Sound in Public Spaces for Health

Rats are indeed annoying rodents when roaming around the house or in the office.

Various traps to catch mice were prepared. From traditional traps with salted fish, food, to cheese stuffed into wire traps. Natural rat repellents as well as chemical repellents that are handled by professionals are also sometimes considered ineffective to repel these tailed rodents.

In the end, ultrasonic sound was used as a way to repel mice.

In addition, other ultrasonic sound ‘transmitters’ in public spaces are also known to be harmful to health.

Research conducted by Southampton University revealed that today’s technological developments make humans surrounded by a lot of ultrasonic pollution every day of their lives.

Professor Leighton, the lead author of the study, revealed that some of the problems with ultrasonic transmitters today, among others, are that automatic doors to rat repellent devices in households are one of the unnoticed causes of ultrasonic pollution.

“There has been a huge increase in the deployment of wearable devices using ultrasonic devices in homes, recreational areas and in the office,” he said.

Mouse Research

Mouse Research

This mouse repellent device using ultrasonic sound waves basically works by emitting sound at a frequency that only rats can hear. These sound waves should make them uncomfortable and leave the area.

Citing various sources, ideally, humans cannot hear this sound, but in reality this voice can still be heard by humans.

“Those who are exposed are often unconscious.”

But things are never ideal or perfect. The worst thing is, the ultrasonic frequency of this mouse repellent not only affects the targeted mice, but also affects humans and pets, one of which is dogs.

Dogs who hear this sound will make them restless and uncomfortable.

In humans, the effects can be much worse. The effect that occurs can be compared to when someone hears an opera singer with a high voice and can break glass at a very high note. This concept will apply like ultrasonic sound to humans.

Ultrasonic frequencies, even when you unconsciously hear them, will have an effect on your condition. This frequency will produce vibrations in the inner ear as well as the brain. As a result, this will cause feelings of discomfort.

In addition to feeling uncomfortable, in a certain period of time, long exposure, and for those whose hearing is sensitive will have an even worse effect.

According to research conducted by the National Institutes of Health (NIH), exposure to ultrasonic noise will cause various health hazards.

Some of the disorders that are often complained of are tinnitus (ringing in the ears), fatigue and sleep disturbances, headaches, chronic migraines, dizziness, nausea, vomiting, and even fainting.

Leighton himself analogized that these waves would disrupt the delicate balance sensors in the ear, confuse the brain, and create symptoms similar to those felt when experiencing seasickness.

However, this condition often occurs in people who are still young to young. The reason is that people’s ability to hear ultrasonic waves decreases with age.
