A. it's probably just a change in the pressure. Similar to yawning to pop your ears on a plane, but I think it was an increase in pressure. Whereas yawning pops are a decrease in pressure. Often times ear infections can occur at the same time as sinus/throat infections.That may help explain the pain.t's probably just a change in the pressure.

The most common unit used to measure frequency is hertz (Hz), which refers to cycles per second; however, there are some other ways to measure frequency, such as revolutions per minute (RPM) for a motor or beats per minute (BPM) for a person's heartbeat.
(hÃ»rts) The SI derived unit used to measure the frequency of vibrations and waves, such as sound waves and electromagnetic waves. One hertz is equal to one cycle per second. The hertz is named after German physicist Heinrich Hertz (1857-1894). The international unit of frequency: one cycle per second.
