MEMS (microelectromechanical systems) microphones are small computerized chips consisting of a capacitive pressure sensor array with an amplifier and analog-to-digital converter built onto the same substrate. They capture sound waves by sensing variation in air pressure through changes in the relative capacitance between their components.
The most notable benefits of using MEMS microphones are their high sensitivity to sound, wide dynamic range, low distortion, noise immunity, and fast start up times due to their small size. Additionally, they require less power than other types of microphones, making them more energy efficient. As a result, many top electronic companies like Apple, Samsung, Amazon Alexa and Google have featured MEMS microphones when manufacturing products to ensure superior audio output for sound capturing applications.
For these reasons alone it’s easy to see why MEMS microphones have quickly become a leading choice for audio engineering professionals across all industries.
Why Mems Microphone Is Necessary?
MEMS microphones are a type of microphone that utilize micro-electromechanical system (MEMS) technology for their operation. They provide high-accuracy audio measurement, improved sound quality and low power consumption, making them perfect for applications where sound is critical, such as mobile phones and medical monitoring equipment. They can also be used in other products such as toys, consumer electronics devices like speakers or headphones and home automation systems. These microphones require very little power while being able to pick up minute details that conventional condenser mics may miss out on. Their superior acoustic fidelity ensures that the user has an experience similar to actually being inside the environment when recording or listening back to sounds through these MEMS microphones vs regular ones.
