According to foreign media reports, in the next two years, the United States and Europe will require all new electric vehicles and new hybrid vehicles to make noise when driving at low speed so that pedestrians can hear cars passing by. But automakers and regulators have yet to determine the form of the noise. Cars think cars should make a "singing voice," while other companies think they can customize it. Now, ayax, an independent car manufacturer and dealer in Uruguay, is even more crazy about the idea of making cars emit a sound that can stimulate plants to absorb nutrients and grow. (photo source: theverge. Com) it is reported that the idea was jointly developed by ayax and the electric factory, a professional audio designer and "smart city expert", neither of which disclosed the project on the website- There are too many details of hy, but in an accompanying press release, ayax explained that choosing a specific bandwidth and frequency range should produce a sound that improves "plant growth, biomass, stomata (promoting water absorption and light utilization), cell division, fluid production in cell walls, and the production of protective enzymes." Although the idea is strange, other automakers are reluctant to share the low-speed noise plan, or some are lobbying the government to delay the implementation of such regulations. Alejandro Curcio, President of ayax, sees his plan as an opportunity for the company and Uruguay. Curcio said that as the first company to assemble Toyota's Hilux pickup in Latin America, Toyota and other companies have always regarded Uruguay as a testing ground for new ideas. Curcio said that ayax has been refitting the Toyota Prius C hybrid vehicle sharing fleet in Uruguay, equipping such vehicles with electronic equipment that can produce dynamic sound, and that Toyota has agreed to expand the pilot to Brazil and Argentina's fleet later this month. Later, Curcio hopes to introduce the idea to executives in Toyota Japan (he says Toyota has been very supportive of the idea for a long time). Juan ciapsesoni, co-founder of electronic factory, is optimistic that ayax will take the lead, and that ayax will gain support from the Uruguayan government. Although there is evidence that sound can affect the growth of plants, hy project pursues a kind of profound sound, after all, the company calls the project "the first sound solution to save the earth in the world". To achieve this grand goal, we need a lot of work. Nevertheless, the voice created by hy project team is very gentle and almost soothing. Other automakers have so far been trying to create a sound similar to the natural whine of electric motors, while not giving up the loud and rough sound of traditional internal combustion engines when accelerating cars. However, the sound created by hy project is more like a kind of low hum, which will increase frequency with the increase of vehicle speed. It seems to be loud enough to remind pedestrians and quiet enough to pacify others.
