The interference produces 'beats' ... two new sounds in addition to the original ones.
The frequencies of the beats are
-- the sum of the two original frequencies and -- the difference of the two original frequencies .
Technically, there are actually even more new sounds than that. There are: -- beats between the beats, and -- beats between each beat and each of the original two sounds. But their amplitudes are so low that they can be detected only with sensitive equipment, and they can't be heard in the presence of the two original sounds and the two 'first order' beats.
When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud - a phenomenon which is called "beating" or producing beats. The beat frequency is equal to the absolute value of the difference in frequency of the two waves.
Abiotic factors are the nonliving physical and chemical components of an ecosystem, while biotic factors are the living components of an ecosystem. Both types of factors affect reproduction and survival
