Özet
The capacity of fishing, passenger, yacht and recreational vessels, especially dry cargo ships and
tankers, is increasing day by day due to the geographical location of our country. Therefore, it is
necessary to optimize the acoustics and vibration, which are dominant in the occupational health
of seafarers, whose number reaches almost 2 million all around the world today. The most accurate
method to be taken for the improvement of mechanical systems that cause noise, vibration and
reverberation is to eliminate the problem at the source as much as possible. For this purpose, since
the machine designs cannot be interfered with, it should be solved at the source of the vibro acoustic with the use of sound absorbing materials in the machine spaces before it spreads to the
space. In this study, the negative and positive effects of the materials used so far for the solution
proposals for the sound and vibration problem are compared and the optimum solution proposals
are listed. The nickel foam panel layer thickness is 5mm and the sound absorption coefficient in
the frequency range of 1000–2000 Hz reaches approximately 0.4. The average sound absorption
coefficient of the copper foam panel is 12.6% at the same thickness [1]. Therefore, sound
absorption performance in the audible low frequency range for a nickel foam panel requires an
appropriate structural design [2]. In addition, the occupational health and safety of seafarers were
evaluated. The effect of exposure to noise and vibration, which consists of work routines on ships,
high risk frequency and high-intensity operations, on work stress has been analyzed. The data were
collected through a questionnaire and analyzed statistically through multiple and simple regression
analyses.
