Knowles Corp. (Itasca Illinois) has introduced a trio of SiSonic MEMS microphones for receptor and wearable applications.

These are: the Titan (digital), Falcon (differential analog), and Robin (single-ended analog) intended for True Wireless Stereo (TWS) earbuds, astute watches, Augmented Reality (AR) glasses and Virtual Reality (VR) headsets.

Knowles states that the Robin offers 66dB SNR and cleanable signals up to 130dB SPL with little than 1 percent distortion. A akin level of awesome clarity holds existent for Falcon, and brings adjacent higher signal-to-noise ratio (SNR) show of 68.5dB further improving TWS applications specified arsenic ambient consciousness with little noise. In debased frequence and speech-band usage cases, Falcon delivers 69dB.

Likewise, Titan offers akin SNR show to Falcon, portion improving artillery beingness by consuming 60 percent little existent (470 microamps) than emblematic integer mics and reducing latency to 3 microseconds, making it suitable for progressive sound cancellation (ANC) and always-on applications successful integer architectures.
