“…The purpose of studies has been to understand the minimum acceptable loudness levels to set the benchmarks and develop aircraft designs accordingly. Research and surveys have documented the effects of different levels of overpressure on living organisms on the ground [15,16] and on building structures [21,22]. Sonic Overpressure responses depend upon the location of the receiver-outside, where direct exposure occurs, or inside a closed structure, in which case the wave is filtered by the materials of the structure.…”

“…However, progressive generation of stress levels and damage due to cumulative sonic booms is a possibility. They can also trigger apparent damage if the structure is weakened because of natural cyclic factors like weather, wind, etc [21]. Another quantitative study [22] focused on damage caused to poorly assembled or maintained buildings by sonic booms.…”

An aircraft exceeding the speed of sound can cover large distances in short amount of time and has several important applications. Thus, there has always been an interest in producing a Supersonic Transport (SST) Aircraft for commercial usage in recent decades. However, the problem of sonic boom restricts operations over inhabited/ land areas. This major obstacle to overland supersonic flight has been subject of governmental and private research for a long time. The research has two parts: minimum acceptable parameters of ground boom signatures for supersonic flight and reduction of Sonic Boom. The methods developed to reduce the boom are generally classified into Aircraft operations, Design, and Exotic methods. This paper reviews the significant methods proposed under each of these categories with special emphasis on design. Due to the range and complexity of methods proposed, there is no consensus amongst the scientific community about the design for an SST. The requirements of low boom design conflict with the requirements of carriage of an effective payload and basic aerodynamics. With the development of high- fidelity CFD and wave propagation programmes like PCBoom, analysing new designs has become easier and understanding of the contribution of various configurations on ground signatures has improved. This has led to promising developments like the X-59 research aircraft, making this field of study one of the most exciting in the aviation industry today.

“…For plaster walls, a pseudo "Fatigue Factor" was assumed equal to the inverse of the observed increase in the length, number or area of cracks in the plaster walls from repeated loading by simulated sonic booms. 80 In this case, the Fatigue Factor exponent varied from -0.30 to -0.43. This indicates the likely presence of a significant true fatigue effect for plaster walls.…”

A study of impulsive noise propagation and its effect on structures has been performed. Propagation and response measurement were conducted on eleven buildings at three military facilities. Sources included artillery and tank gun firing and explosive ordinance disposal. Propagation measurements demonstrated that the primary path is airborne, not groundborne. Frequency Response Functions were developed for the measured structures, and a general single degree of freedom model for structural velocity response was prepared. A model for Probability of Damage from impulsive noise sources was developed and is presented. That model addresses a wide range of structure types, and provides guidance for impulsive noise criteria in communities.
