1.	A _______________ is produced when part of the atmosphere is compressed suddenly.(a) Vacuum(b) Heat(c) Smog(d) SoundI have been asked this question in unit test.This interesting question is from Acoustic Design of Auditorium topic in chapter Acoustics and Ventilation of Construction & Building Materials
Answer» Right answer is (d) SOUND The best I can explain: The compression produced in the atmosphere is propagated or spread away from the source. HENCE, the Sound travels in the form of WAVES and when these waves come near over ear drums, we FEEL the sensation of hearing.
