If apparent change in frequency of sound heard by a listener is less than, the actual frequency of sound emitted by source. Then it means that

_____is the frequency of the sound as heard by the listener.

Is it possible that the apparent frequency of the sound heard by a moving listener is the same as the true frequency ? If so give an example,

A source of sound when moves towards a stationary observer, then frequency of the sound heard by listener is more than actual frequency because the

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is 25 % more than the actual frequency. If the speed of sound is v , that of the source is
