They would be inverted, but your
ears brain can't tell the difference. Remember that the human ear's audible range is from 80Hz - 20kHz. Picture a waveform (see below). At 80Hz, a sound wave oscillates above (pressurized air) and below (rarified air) the horizontal axis (neutral pressure, 0dB) 80 times in one second. At 20kHz, it's 20,000 times in one second. Your
ear brain can't tell the difference.
You can prove it to yourself by using a sound editor on your computer to invert a sound clip and compare the before and after.
