Hearing Aid Components & Accessories
Together, we can do more for the hearing impaired — starting with an improved integrated faceplate for the manufacturing and servicing of hearing aids, as well as the development of better hearing aid component designs.
Accessories
Hearing aid performance is enhanced by such design refinements as sound damping, wax minimization and maintenance.
Sensors
Special application and performance requirements are addressed by our unique accelerometer and ultrasonic designs.
Multicore DSP
The Knowles AISonic™ Audio Edge Processor IA8201 is a high-performance, ultra-low power audio-centric OpenDSP supporting up to 4 mics, multiple high speed interfaces and GPIOs in two package options (eWLB and QFN). IA8508 combines three Tensilica-based, audio-centric DSP cores with an ARM Cortex M4 to maximize design flexibility. The DSP cores provide low-latency, high-capacity processing for audio and machine learning computations, while the Cortex M4 blends signal processing with general-purpose controller capability. The platform leverages 4MB of user available RAM to enable multiple simultaneous use cases and can be advantageously configured into an ultra-low power system. See page 2 for detailed core information.
Boom
Knowles의 붐 마이크는 유연하거나 견고한 구성 모두를 위해 설계되었으며 가깝거나 먼 거리의 현장 응답에 대한 소음 절감 및 고주파수 크로스오버와 같은 성능 옵션을 제공합니다. 길이 및 말단 유형은 어플리케이션 필요 사항을 충족하기 위해 맞춤화되어 있습니다. 헤드셋 및 오디오 시스템 마케터들이 Knowles 붐 디자인을 구하는 경우가 종종 있습니다. 상업, 정부 및 산업 디자이너들과의 협업을 통해 항공기, 군사, 응급 요원 및 고소음 제조 환경을 위한 새로운 헬멧 어플리케이션을 구현할 수 있었습니다.
Accelerometers
The BU Series piezo-ceramic accelerometer has output from 20 Hz to above 10 kHz, and is used primarily as a contact microphone for high noise environments. It may also be used as an accelerometer with lightweight structures. As a contact microphone, the BU may be worn on the throat, or touching a bony part of the head (top, temple, or mastoid bone). BU has been integrated into helmet designs for radio communication for military and emergency services.
MQM Series
The MQM is the smallest and most production friendly hearing instrument microphone offered. Utilizing Knowles MEMS technology, the MQM allows for efficient reflow soldering assembly. The MQM offers unmatched performance in reliability and environmental stability. The MQM also offers best in class vibration sensitivity performance. It is ideal for matched omni-directional pair applications as well as applications where the smallest possible size is required.
MM20 Series
Using Knowles’ proven high performance MEMS technology, the MM20 consists of an acoustic sensor, a low noise input buffer, and an output amplifier. These devices are suitable for applications where excellent wideband audio performance and RF immunity are required.
