![]() ![]() The pilots themselves cannot hear the sonic booms but can manage to see a wave emanating from behind the aircraft they're carrying.Įxperts and scientists are trying hard to reduce the effects of the sonic boom on the ground level. The sonic boom from aircraft can cause ground-level damage, i.e can break glasses of buildings and houses or shatter windows. To summarise, sonic booms are produced when objects travel beyond the speed of sound, due to the concentration of pressure waves to form shock waves, which possess a huge amount of energy. But work is underway by the legislators and industry experts in framing guidelines to lessen the impact of sonic booms. In the present scenario, there are no standards prescribed legally for sonic booms. Grassy and shrubby cover on the ground can lessen the impact of the sonic waves by absorbing them. Even hard surfaces like concrete, tar, marble can reflect the waves and produce a doubled-up booming effect. Atmospheric effects like temperature, humidity, pollution, winds can also affect the sonic boom felt on the ground. A simple explanation of this is they don't fall in the hypothetical 3D conical figure on which the sonic boom has its effects. The borders don't hear the sonic boom at all. The boom is continuous for the entire supersonic flight time and not only during the transition from subsonic to supersonic wave, which in general is a misconception among many.Īn obvious question might arise, " Do the on-borders hear the sonic boom?" Well, the answer is "No". The sound is much similar to mortar bombs. The sonic booms sound like a deep double "boom" as the aircraft passes by. The sound produced by the sonic booms to a great extent depends on the distance between the observer and the shape of the aircraft producing the sonic boom. In modern times, FM levels of 1 or lower are acceptable. The lesser the FM an aircraft has, the lesser the boom it generates. The figure of Merit or FM was a characteristic of the length of the aircraft and its length. Richard Seebass and one of his colleagues Albert George studied the problem carefully and finally went to introduce the "figure of merit". It was believed that by flying high the problem of sonic booms could be avoided but it was later proved to be untrue. With the increase in the number of supersonic aircraft carriers, there arises a problem of sonic booms affecting general people on the ground. The pressure generated through shock waves by an aircraft is generally a few pounds per square foot. Let's say the wing head or engine inlet of an aircraft. Sometimes several secondary smaller shock waves are formed at some convex points on the object. The power or intensity of the shockwave depends on the amount of air involved or in a way the size of the object being accelerated is called sonic boom speed. This results in a wave merger, into a single shock wave. But with the increase in velocity of the object in the air to the speed of sound, the airwaves are compressed or forced together. Unlike waves on water, these waves travel at the speed of sound. Hence similar to the waves created on the water when an object travels on it, waves are created in the air as well. Similar to that of water, the air is also fluid with lesser density. But the exact sonic boom meaning was explained here scientifically. As the object passes, the observer experiences the boom for a very brief period.Īs per the sonic boom definition when the object moves more than the speed of sound a huge noise is created. As the object moves, the imaginary conical effect region also moves with it. If you're in that zone, you will experience a sonic sound as the object passes you. A sonic boom can be experienced in the zone of an imaginary 3D cone at the back of that object. Imagine an object travelling at supersonic speed. Large supersonic aircraft produce sonic waves that can be startling and may awaken you or cause a bit of damage, like cracks in your window glasses.Ī supersonic beam, although powerful cannot be heard in all directions. When an object travels at a speed greater than the speed of sound, shock waves are generated and a huge amount of energy is liberated. Some people get scared or amazed after witnessing a sonic boom sound, but it has become common these days with a large number of supersonic jets and rockets around. When objects travel at speeds more than the speed of sound, this phenomenon is called a sonic boom. ![]()
