Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. 10 log (100 x 10^(6)/ 10^(-12)) = 200 dB.
Sound Quality. If I were to put the G-Boom on a scale of 1-10 in the sound quality department, it's easily an 8, maybe even a 9. And when price is also considered, it's a 10. For $99, I can't believe how good this boombox sounds â it's comparable to speakers costing twice, or even thrice, its price.
