Loudness

Loud noise (143 dB), sonic boom glass failure... 

The results clearly indicated that the ventilation noise was perceived as most acceptable when the tone was situated in the low er part of the frequency range. The experience of disturbance and the associated effects occur at exposure levels above the auditory perception threshold. Above this level, the risk of these effects increases as the perceived loudness increases, provided that the other conditions remain constant. Since the loudness can be predicted relatively accurately by means of technical measurements, any differences in the degree of disturbance can also be predicted by reference to these measurements, provided that they are dependent on differences in the loudness. 

The operator took about one to two minutes to open the valve halfway very soon afterward, there was a loud bang as a 6-in. cast-iron valve on a branch (unused and blanked) failed as a result of water hammer. The operator was able to climb out of the pit, but later died from his burns, which covered 65% of his body [17J. Figure 9-11 explains the mechanism.

Through the 1920s Houdry had experimented in France on a number of possible catalytic routes to higher octane fuel. Finding little success in France, he came to the United States to further develop his process. After initial attempts at commercialization under the sponsorship of Sacony-Vacuum Company (currently Mobil) in Paulsboro, New Jersey, failed, I loudly and his development company, Houdiy Process Corporation, moved to Sun.
