ECHIZEN, Fukui – Enjoy the silence. Perhaps this is the motto for a set of bizarre clean rooms at the facilities of a Japanese audio equipment maker, designed to eliminate all sound and electromagnetic interference from beyond their walls.
Audio-Technica Fukui Co.’s electromagnetic anechoic chambers are designed to measure the radio waves emitted by devices such as microphones and wireless headphones with very high accuracy, so the company can be sure they are complying with the different radio emission standards of each country. This means that the rooms – each 8.6 meters high, 20 m long and 12 wide – must block external electromagnetic interference.
The company was founded 51 years ago as a production subsidiary of Audio-Technica Corp. It mainly manufactures turntable needles, but also offers lines of general audio equipment including microphones, headphones, amplifiers and speakers. Its microphones are even used in the office of the Japanese Prime Minister.
With the popularization of smartphones and video streaming services such as YouTube, the demand for wireless headphones and earphones has increased all over the world.
Audio-Technica Fukui General Manager Takumi Tanishita, 58, said: “We offer a range of high quality technologies that can be used in products ranging from analog to digital. We aim to develop better quality products as online conferencing and telecommuting becomes more and more common amid the coronavirus pandemic. ”
