ADI bottom sound hole MEMS microphone dustproof and liquid infiltration sealing recommendations
ADI’s bottom sound hole MEMS microphone can be soldered directly to the PCB by reflow soldering. A hole needs to be made in the PCB to pass sound into the microphone package. In addition, the housing that houses the PCB and microphone has an opening to allow the microphone to communicate wi...Read more -

Microphone Sensitivity
Sensitivity, the ratio of the analog output voltage or digital output value to the input pressure, is a key metric for any microphone. With the input known, the mapping from acoustic domain units to electrical domain units determines the magnitude of the microphone output signal. This article wil...Read more -

Microphone sensitivity
The sensitivity of a microphone is the electrical response of its output to a given standard acoustic input. The standard reference input signal used for microphone sensitivity measurements is a 94dB sound pressure level (SPL) or a 1 kHz sine wave at 1 Pa (Pa, a measure of pressure). For a fixed ...Read more -

Anechoic chamber
An anechoic chamber is a space that can completely absorb sound waves. The room is insulated from external noise, with wedge-shaped fiberglass wool covering the entire ceiling, floor and walls, which dissipates all the energy of the sound waves, thus completely eliminating echoes. An anechoic cha...Read more -

MEMS MIC Sound Inlet Design Guide
It is recommended that the external sound holes on the whole case be as close to the MIC as possible, which can simplify the design of gaskets and related mechanical structures. At the same time, the sound hole should be kept as far away as possible from speakers and other noise sources to minimi...Read more -
Electroacoustic components
Electroacoustic components refer to components that use electromagnetic induction, electrostatic induction or piezoelectric effect to realize the mutual conversion of electrical signals and sound signals. Products in the electro-acoustic industry traditionally include two categories of ele...Read more
