Karaoke crooners have Bayer MaterialScience to thank if they find a new set of audio speakers from American Technology Corporation (ATC) beneath their tree on Christmas morning.

ATC’s new H450 and H460 speakers have transparent transducer housings molded from Bayer’s Makrolon 2558 polycarbonate (PC) resin as a crucial component to their hypersonic sound technology systems. These systems allow audio information, such as a singer’s voice, to be focused so precisely that the message moves directly from the speaker to an intended audience of one, or 100, without missing the target — ideal for creating clear music while significantly reducing noise pollution in both open and confined spaces.

“Makrolon PC resin replaced a part of the hypersonic sound device that was previously machined out of aluminum, resulting in vast improvements in cost and weight,” said Nancho Lopez, director of engineering with the San Diego, Calif.-based ATC. “The material also allowed for a new bonding process that improved production cycle times and yields, and resulted in lower materials and assembly costs.”
