Practice Sound RRB PYQ questions asked in various Railway Recruitment Board examinations. This page provides important previous year questions from the Sound chapter along with correct answers and clear explanations to help you prepare effectively for RRB Physics.
The Sound chapter covers important concepts such as the nature of sound waves, frequency range of sound waves, speed of sound, characteristics of sound, echo, SONAR and RADAR. These concepts are important for understanding the types of Physics questions commonly asked in Railway examinations.
Start practicing Sound RRB PYQs with answers and explanations and strengthen your Railway Physics preparation.

We hear people speaking in an adjacent room because sound waves undergo:
RRB NTPC (Stage-I)

2021
✓ Answer:BDiffraction
Diffraction allows sound to spread around edges and through openings into neighbouring spaces.
192
What are auditorium roofs and walls covered with to reduce echoes?
RRB Group-D
30/10/2018 (Shift-III)

✓ Answer:BFibreboard
Acoustic fibreboard absorbs sound and reduces strong reflections.
193
Arrange solids, liquids and gases in the usual descending order of sound speed.
RRB JE CBT-II

2019
✓ Answer:ASolids, liquids, gases
The usual school-level comparison is solids > liquids > gases, although particular materials can be exceptions.
194
The persistence of sound in an auditorium due to repeated reflections is called:
RRB NTPC (Stage-I)
16/01/2021 (Shift-I)
2021
✓ Answer:BReverberation
Multiple reflections continue after the direct sound and produce reverberation.
195
Echoes may be heard more than once due to successive or multiple:
