Assessment of amplitude characteristics of acoustic pressure inside the head fairing

Based on the experimental data obtained during flight design tests of the launch vehicle and calculation work, the realized spectral levels of acoustic pressure are presented in the paper. Moreover, based on the assumption of the linearity of the wave processes inside the head fairing, an acoustic load verification method is developed and tested using the standard head fairing. This paper talks about influence of vibrational noise on the readings of acoustic sensors at the launch site of the launch vehicle mounted on the shell of the head fairing, and quite adequate measurement results in flight.
