Those who can see their environments often do not readily perceive echoes from nearby objects, due to an echo suppression phenomenon brought on by the precedence effect. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability. [2]
Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water . It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight , along with knowledge of the speed of sound in water, allows determining the distance ...
Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of sonar; Gunfire locator; Human echolocation, the use of echolocation by blind people; Human bycatch
Echo sounding is a process used to determine the depth of water beneath ships and boats. A type of active sonar, echo sounding is the transmission of an acoustic pulse directly downwards to the seabed, measuring the time between transmission and echo return, after having hit the bottom and bouncing back to its ship of origin.
Human echolocation, the use of sound by people to navigate. Sonar (sound navigation and ranging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines. Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of Sonar.
The basic components of the scientific echo sounder hardware function is to transmit the sound, receive, filter and amplify, record, and analyze the echoes. While there are many manufacturers of commercially available "fish-finders," quantitative analysis requires that measurements be made with calibrated echo sounder equipment, having high ...
Echoic memory is the sensory memory that registers specific to auditory information (sounds). Once an auditory stimulus is heard, it is stored in memory so that it can be processed and understood. [1]
The World Forum for Acoustic Ecology is an international collective of people and organizations who study the world's soundscapes. [6] There are eight groups that make up the World Forum for Acoustic Ecology: the Australian Forum for Acoustic Ecology, the Canadian Association for Acoustic Ecology, the Finnish Society for Acoustic Ecology, the Hellenic Society for Acoustic Ecology, the Japanese ...
