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.
Frequency is a metric for expressing the rate of oscillation in a wave. For planar and longitudinal waves, this often expressed in oscillations-per-second or Hz. Angular frequâ¦ency used for expressing rates of rotation, similar to revolutions-per-second, and is usually expressed in radians-per-second.
