This peak sound pressure level is significantly less than the 140 dB level generally associated with the potential for an immediate PTS.
The acoustic control system display in the high-intensity acoustic chamber at KARI shows the sound pressure level (SPL) at each one-third octave band of the eight channels being monitored.
The sound pressure level is easily affected by various noises, so it is necessary to correct their influence.

The increase of the values of sound pressure level at the aforementioned points could be explained by the fact that the closer they are to the surfaces reflecting the sound well (in this case these are the floors of testing laboratory and one of its walls), the reflected sound wave is summarized with the waves that have passed through the obstacle and that have passed by it.
The reduced sound pressure level minimises workplace noise stress, with reduced air consumption and lower energy costs being additional advantages.
