An airplane mechanic notices that the sound from a twin-engine aircraft rapidly varies in loudness when both engines are running What could be causing this variation from loud to soft?

The engines are running at slightly different frequencies, so their sounds combine to make beat notes whose amplitudes vary quickly.

the loud ness of the sound increase becouse frequencie depend on loudness

What is loudness mesured in?
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".
What is a unit to compare loudness?
Decibels can compare loudness
Is decibel a unit of loudness?
yes it is a unit of loudness
Pitch is to frequency as loudness is to?
Loudness depends on the amplitude. square of amplitude is proportional to the loudness. Pitch is decided by the frequency. One can sing at higher pitch but at lower voice.
What units is the loudness of sound measured?
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"

What is the unit of the loudness of sound?
Loudness is the quality of a sound that is primarily a psychological correlate of physical strength or amplitude. You can try to measure the sound pressure in decibels. Scroll down to related links and look at "Loudness in sones - Wikipedia ", Loudness level in phon - Wikipedia ", and Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage).
