According to Acer specs: "Dual microphone with noise and echo cancellation". So there should be 2 "holes."
Echo cancellation typically listens to the sound emitted from the speakers and nulls out that same sound as it comes thru the mic.
Noise cancellation does somewhat the same. Noise Canceling mics are typically NOT front facing.
So I'm betting the second mic would be behind the speaker grill, but I have no clue exactly where.
