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.
The derived SI unit for frequency is hertz (Hz) The common metric multipliers are: kilohertz (kHz) = 1,000 Hz Megahertz (MHz) = 1,000,000 Hz and Gigahertz (GHz) = 1,00 â¦ 0,000,000 Hz. 15 people found this useful. Pitch and frequency both are measured in simple hertz.
