MEMS microphones expected to witness the fastest growth during the forecast period

MEMS microphones expected to grow with the highest CAGR during the forecast period. The growth of this segment can be attributed to the increasing adoption of MEMS microphones in IoT enabled electronic devices, because of its miniature design. MEMS microphones enable considerable advancements in sound quality in applications which utilize multiple microphones. This increases the performance of these audio components by providing benefits such as high sound-to-noise ratio (SNR) and improved noise cancellation. Other benefits include small form factors, superior temperature stability, and long battery life due to low current consumption. MEMS microphones when embedded in smartphones enables the execution of active noise and echo canceling that helps isolate a sound and its location. These features have made MEMS microphones increasingly popular among smartphone manufacturers across the world.

Digital MEMS microphones to account for largest market share of the microphone market in 2019

Digital MEMS microphones dominated the microphone market in 2019. Digital microphones use dielectric wafers or thin-film transducers to capture sound which permits them to offer a smaller package size, effective immunity to noise, low power consumption, and more precise sound reproduction. Therefore, these microphones are in demand for use in automotive infotainment solutions and IoT enabled electronic devices as they facilitate a hands-free human–machine interaction with high quality audio.

Medical application segment estimated to grow at the second highest CAGR during the forecast period

The latest trend in the market is to tap the power of smartphones for medical and health-related operations. AliveCor’s heart monitor KardiaMobile for smartphones and tablets is an excellent example in this field. The device collects ECG data with the help of electrodes from the skin and converts it into ultrasonic FM sound signals. These signals are then sent to the microphones embedded in the smartphone. Microphones working as acoustic sensors are used in wireless sound monitoring applications, including breathing sounds in apnea patients, chest sounds after cardiac surgery, as well as for feedback sensing in compression vests used for respiratory ventilation. The increasing application of microphones in medical application is expected to contribute to the market growth during the forecast period.
