Loud sound rattles Mysureans: It was not earthquake but a Sonic Boom

February 23, 2018

Mysuru: It was neither an earthquake nor a quarry blast. The loud sound that was heard at around 12.45 pm yesterday was in fact, a ‘Sonic Boom’ created by a Supersonic Jet. Due to the loud sound, rumours spread that there was an earthquake.

Panicked residents, especially from Kuvempunagar, Saraswathipuram, V.V. Puram, Railway Yard, Paduvarahalli, Yadavagiri and Bannimantap, even complained that the vessels in their houses shook and fell off the shelves.

A Sonic Boom is a loud noise created by the ‘shock wave’ produced by a Supersonic Jet that is travelling faster than sound. Normally, for a plane that is going at sub-sonic speeds (lower than that of sound), the sound of the plane is radiated in all directions, but at supersonic speed, it is going faster than the speed of its sound and that’s when ‘Sonic Boom’ occurs.

Speaking to Star of Mysore, Karthik, a resident of the city who is preparing for his Civil Services examinations said that if a plane (a jet) is travelling slower than the speed of sound, then sound waves can propagate ahead of the plane. If the plane breaks the sound barrier and flies faster than the speed of sound, it produces a Sonic Boom when it flies past.

The boom is the “wake” of the plane’s sound waves. The sound waves that would have normally propagated ahead of the plane are combined together so at first you hear nothing, and then you hear the boom they create, he said. Sonic Booms generate large amount of sound energy, sounding like an explosion, he added.

    3 days after the incident, we are still being speculative about the source of the noise. That is not good for the city.

  2. Dr.A.V.Balakrishna says:

    The incident has led to open chapters in Physics to academically know how a sonic boom. Who cares what boom causes such threat and try to know as if we are sitting in a class room. The department and those responsible must come up and Infact must forecast news for people safety

    I heard the sound when I was driving. It was almost a diwali atom bomb blast inside my ears.
    That’s what I felt.

    But we have right to know about the happening in detail from the respective department and individuals. I seriously want to know what happened and why it happened. Start of Mysore, please take actions in bringing answer to the big question in the minds of people living in one of the safest cities of India.
