Consider the following statements regarding sound wave propagation and audible enclaves:

1. When sound waves travel through a medium, they spread out due to diffraction, influencing their direction and intensity.

2. Audible enclaves are localized pockets of sound that can be heard only by specific individuals without affecting the surrounding noise environment.

3. Lower frequency sound waves, rather than higher frequency ones, tend to spread out more rapidly as they propagate, making them more difficult to confine within a directed beam.

Which of the statements given above is/are correct?
