Summary
This study analyzed noise on fishing vessels, finding high sound levels near 90 dB(A) impacting workers. Sound absorptive treatments were modeled to estimate noise reduction, aiming to mitigate risks from engine noise.
Area of Science:
- Marine Engineering
- Acoustics
- Occupational Health
Context:
- Fishing vessels experience significant noise pollution.
- Occupational noise exposure poses health risks to maritime workers.
- Engine noise is a primary contributor to high sound levels onboard.
Purpose:
- To analyze noise levels during navigation and fishing activities on vessels.
- To measure reverberation, sound insulation, and engine vibrations.
- To estimate potential noise reduction through sound absorptive treatments.
Summary:
- Noise analysis conducted on five vessels revealed sound levels near 90 dB(A) in operational areas and significant noise in rest areas.
- Exposure levels ranged from 80 to 90 dB(A) based on working time.
- Measurements included reverberation times, sound insulation, and engine vibrations for docked vessels.
Impact:
- Identified key areas for noise intervention to reduce occupational risk.
- Provided data for modeling noise level reduction using sound absorptive treatments.
- Contributes to improving working conditions and health for seafarers.

The origin of Earth's ocean tides has been a subject of continuous investigation for over 2000 years. However, the work of Newton is considered to be the beginning of the proper understanding of the phenomenon. Ocean tides are the result of gravitational tidal forces. These same tidal forces are present in any astronomical body; they are responsible for the internal heat that creates the volcanic activity on Io, one of Jupiter's moons, and the breakup of stars that get too close to...

00:53Sound Waves: Interference
4.2K
Sound waves can be modeled either as longitudinal waves, wherein the molecules of the medium oscillate around an equilibrium position, or as pressure waves. When two identical waves from the same source superimpose on each other, the combination of two crests or two troughs results in amplitude reinforcement known as constructive interference. If two identical waves, that are initially in phase, become out of phase because of different path lengths, the combination of crests with troughs...

01:07Damped Oscillations
6.2K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
