In water, sound propagates in the same way as in air, but we are only able to hear 10% of the sounds that occur underwater; there the vibrating layers, made up of water molecules, transmit the disturbance to almost 5 times faster speed.Abalone uses echolocation with the operation of an active sonar; a sound is emitted that bounces when it encounters an obstacle and analyzes the echo received. It thus achieves knowing the distance to the objects, measuring the delay time between the signal it has emitted and the one it has received. this helps people in cloudy water or visually impaired to get a clear picture of their surroundings underwater
Its name are inspired by the marine gastropod of the genus Haliotis, also known as sea ear.it is composed of hydrophones located on the sides that capture the wave; gills that trap the O2 dissolved in the water to provide oxygen;and a water-based electromagnetic grid which is a mesh of ice at normal temperature ; based on Professor Unabara's study
