The interference of two sound waves of similar amplitude but slightly different frequencies produces a loud-soft-loud oscillation we call __________.
The Doppler effect
vibrato
constructive and destructive interference
beats
Homework Answers
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source.
vibrato is the amount of pitch variation in sound wave.
Constructive interference occurs when both waves are positive and the total displacement of the medium is larger than it would be for either wave separately.
Destructive interference is when the displacement of the medium where the waves overlap is
less than it would be due to either of the waves separately.
The ear hears a single tone that is modulated.The distinctive sound pattern is called beats
so,answer is beats

A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.24×105 Pa . The speed of sound in air is 344 m/s. What is the highest-frequency sound to which this machine can...
