Knowles is the leading international manufacturer of technologically advanced micro-acoustics products. The Company has leveraged its core competency in acoustic technology to build expertise in hearing aid transducers (microphones and receivers), electromechanical components, low voltage integrated circuit design, micro-electrical mechanical systems (?MEMS?) and precision manufacturing.
Knowles develops, manufactures and supplies audio communications components, primarily miniaturized microphones, receivers and electromechanical components, for use in hearing aids and manufactures high performance transducers for use in pro-audio devices, high-end headsets, medical devices, military headsets and far field arrays. Knowles is the world?s largest manufacturer of high performance transducers used for hearing aids and other high quality acoustic applications.

Knowles also designs, manufactures and assembles microphones for use in the personal mobile device and communications markets including mobile phones, PDAs, Bluetooth headsets and laptop computers. The core product suite for these applications is the SiSonic? silicon microphone, manufactured from poly-silicon and based on MEMS technology that is widely expected to be the future microphone technology standard in mobile phones and consumer electronics. This revolutionary product takes advantage of semiconductor manufacturing processes that result in a robust microphone that yields a high degree of repeatability, stable acoustic performance and flexibility for future design enhancements. Knowles also manufactures traditional electret condenser microphones for these applications.

Knowles is committed to quality and all manufacturing facilities are state of the art and ISO 9001 or 9002 certified. The Knowles Quality Management System and company-wide Oracle ERP system ensures design integrity, efficient manufacturing and cost effective on-time delivery of products
