In order to ensure that we can make a lot of noise in parties and concerts and provide clearer voice in daily life, HTC One uses dual membrane microphones, while single membrane microphones are mostly used in the market. It is also a highly sensitive dual membrane microphone! HTC's official blog announced that HTC One used a dual film MEMS microphone to record audio, and the two films used have a specific scope of use, one focusing on high pitch and the other on high sensitivity. With this technology, the background noise will be greatly reduced, providing clearer voice calls.
