Peak Sound Pressure Levels and Associated Auditory Risk from an H[subscript 2]-Air "Egg-Splosion"
Dolhun, John J.
Journal of Chemical Education, v93 n12 p2123-2125 Dec 2016
The noise level from exploding chemical demonstrations and the effect they could have on audiences, especially young children, needs attention. Auditory risk from H[subscript 2]- O2 balloon explosions have been studied, but no studies have been done on H[subscript 2]-air "eggsplosions." The peak sound pressure level (SPL) was measured for the first time and compared to the recommended SPL limits and some recently published work. All peak SPL results ended above 125 dB, some greater than 150 dB. The SPL results exceeded the World Health Organization (WHO) safe limits of 120 dB for children and 140 dB for adults.
