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.
Wavelength is also measured in metres (m) - it is a length after all. The frequency, f, of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one wave per second.he frequency, f, of a wave is the number of waves passing a point in a certain time.
