Use this guide to replace the microphone array assembly in an Early 2020 MacBook Air.
To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.
Do not reuse the battery if it is swollen or was deformed in any way during the procedure. The battery is likely damaged and can be very dangerous to reuse—it should be replaced.
This guide involves removing the speakers and battery. You will need new adhesive to properly reinstall the speakers and battery.
