An echo is heard after a delay because sound waves take time to travel to a reflecting surface and back to the listener. The speed of sound in air is approximately 343 meters per second. Therefore, if the reflecting surface is about 17 meters away, the sound will take roughly 0.1 seconds to travel to the surface and return, resulting in the listener hearing an echo after that time.

When did Echo Point end?
Echo Point ended on 1995-12-01.
A sound wave traveling at three hundred twenty m per sec is emitted by the foghorn of a tugboat An echo is heard two point zero seven sec later How far away is the reflecting object Answer in units m?
The wave travels at 320m/s The echo is heard 2.07 seconds later In 2.7 seconds, the sound wave has traveled 350m/s*2.07s=724.5m Because the sound wave has traveled the distance from the tugboat to the reflecting object twice(once going out, once back), the final distance must be divided by 2 724.5m/2=362.25m The reflecting object is 362.25m away
MATLAB program code for controlling echo?
To control echo in MATLAB, you can use the audiorecorder function to capture audio and the audioplayer function to play it back with an echo effect. Here's a simple example: fs = 44100; % Sampling frequency recObj = audiorecorder(fs, 16, 1); % Create audio recorder disp('Start speaking.') recordblocking(recObj, 5); % Record for 5 seconds disp('End of Recording.'); % Get the audio data audioData = getaudiodata(recObj); % Create echo effect by delaying the signal delay = round(0.2 * fs); % Delay of 0.2 seconds echoData = [audioData; zeros(delay, 1)]; % Add zeros for delay echoData(delay+1:end) = echoData(delay+1:end) + 0.5 * audioData; % Add echo % Play the audio with echo sound(echoData, fs); This code records audio for 5 seconds, applies an echo effect, and plays it back. Adjust the delay and gain factor (0.5 in this case) to modify the echo characteristics.
How long does an echo last in a big room?
The duration of an echo in a big room can vary significantly based on factors like the room's size, shape, and the materials of its surfaces. Generally, an echo can last from a fraction of a second to several seconds. In large, open spaces with hard surfaces, echoes may persist longer as sound waves bounce off the walls. In contrast, softer materials or furnishings can absorb sound and shorten the echo's duration.
If Sound travels through air at 330 meters per second how long will it take a bat's cry to reach its prey and echo back if the prey is 1 meter away?
The total distance traveled by the sound wave is 2 m. At a rate of 330 m/s, it will take 0.00606 seconds for the bat to hear the echo.
How far away are you if it takes 15 seconds to hear an echo?
If it takes 15 seconds for an echo to be heard, the distance between you and the reflecting surface (such as a wall, cliff, or building) is approximately 2,250 meters (15 seconds multiplied by the speed of sound at sea level, which is about 343 meters per second).

The iceberg is 1372 meters away.
