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 energy in a sound wave can be measured using Decibels. The Decibel Meter shows examples of things that make noise and measurements in decibels. Amplitude measures how forceful the wave is. It is measured in decibels or dBA of sound pressure. 0 dBA is the softest level that a person can hear.
