Microelectromechanical systems (MEMS) technology is used for many sensing applications including microphones. The MEMS microphone provides a design alternative to Electret Condenser Microphones (ECMs) for many consumer electronic and mobile products. With this goal in mind, Infineon Technologies silicon microphones have been designed to extend the benefits of lowest possible self-noise (high SNR) and lowest […]
Noise cancellation
What does it take to overcome audio noise?
At Sensor Expo 2019, Edoardo Gallizio from product marketing for MEMS & Sensors in the Americas at STMicroelectronics explains a voice recognition demo using sensor fusion that was development in conjunction with partner bdSound. The system is a reference design that uses ST’s MP23DB01HP digital microelectromechanical systems (MEMS) microphone and the LIS25BA audio accelerometer to […]
How can you reduce audio noise in an airport?
At Sensors Expo 2018, Giovanni De Majo from audio and pressure sensor product marketing at ams, demonstrates how his company’s AS3415 Active Noise Cancellation (ANC) chip can help reduce the background noise for headphone users in an airport, car or airplane. Selecting between the noise situation in an airplane car or airport De Majo chooses […]
