South Korean consumer electronics manufacturer LG launched a new TV in India claiming to help India fight malaria and dengue fever.
LG said that the television has a device that can use ultrasonic technology to emit high-frequency sound waves, human ears cannot hear high-frequency sound waves, but mosquitoes and some insects can hear, and they very much hate this sound wave, so to reach the drive The purpose of mosquitoes. The LG said that televisions do not emit any harmful radiation when used, and are intended to improve the traditional method of repelling mosquitoes. Of course this TV is only useful when turned on.
But is this technology really easy to use?
About this TV LG did not disclose many details, but this is not LG for the first time involved in mosquito technology - it has already started selling mosquito repellent air conditioning in 18 countries in Africa, but also uses the same ultrasonic equipment (30-100KHZ) to drive mosquitoes .
The control laboratory at the University of Ibadan, Nigeria, tested and turned on the air conditioner for 24 hours, driving an average of 62.7% of mosquitoes.
The use of ultrasonic equipment to drive out pests has been a hot topic for scientists to study, but in the past 20 years, a number of scientific studies have found that the operation of such equipment is not as good as imagined.
Therefore, how these new television effects are still unknown, in fact, in the mosquito repellent air conditioning products page, LG himself also wrote, "The product has the effect of repelling mosquitoes, but it does not mean that it can replace other protective measures. â€
