“…Research on the audible display of alarms has been conducted in various fields such as nuclear power research institutes, the aircraft industry, and hospitals. In the maritime field, there have been studies suggesting the application of auditory icons (environment sound alarm) instead of the existing abstract sound and studies to suggest the application of voice alarm to ECDIS [10][11][12].…”

Along with the development of ship navigational equipment, ship operators have to process a larger amount of information than before and be exposed to more alarm sounds. These ships’ bridge environment increases burdens to ship operators. One of the methods proposed to solve this problem is the audible voice alarm method. However, there is a lack of studies that objectively prove the efficacy of the method. Therefore, in this study, a comparative experiment was performed to confirm the effect by applying the method to an electronic chart display and information system (ECDIS), a representative navigation instrument. We analyzed collected data according to a data-driven process and confirmed the difference between a traditional alarm method and the audible voice alarm method by distinguishing groups through clustering.

“…Many ships are heavy, and therefore it's not easy for a ship to turn or stop like an automobile due to large inertia (Park et al 2017). Every ship is equipped with radar which gives the information of other ships nearby (Kim, Lee, and Youn 2020;Xu, Guan, and Xia 2020). Nevertheless, there is a possibility of causing an accident due to poor visibility such as from dense fog or heavy rain (Joseph and Dalaklis 2021).…”

Applying the directionality of an acoustic meta-lens, a sound reception system for ships is designed. A two-dimensional disk shape acoustic meta-lens or an acoustic Luneburg lens made of 253 acrylic pipes of different radii which control the refractive index is used. The lens has the diameter of 180 cm and the thickness of 20 cm. Eight microphones were installed around the edges of the lens because the lens focuses the input signal into the edge of the other side of the lens. The sound reception ability of the lens was tested on the sea using the horn of a university training ship as an emitter and the lens loaded on a small boat as a receiver. Both are moving at 20 ~ 40 km/h at a distance between 300 ~ 700 m. The lens could focus to recognize the direction of the input sound in the frequency range between 300 and 900 Hz.
