    An echo is a reflection of sound and it arrive at the listener some time period after the direct sound happened.  It is a single reflection from the source of the sound and the time delay is the extra distance divided by the speed of sound.

    Echos are the result of sound waves bouncing off another object.  Sound itself is produced when units of air are moved around and bounce off other molecules to form a sound wave.  As the sound wave travels through matter (air, liquid, or solid), it may hit another object and bounce back, creating the sound waves to continue traveling (sometimes back to you).  An echo more likely occurs when there are more objects for it to bounce off of.

    An echo is the reflection of a sound waves as it hits a target solid surface and arrive to the listener some period of time after the direct sound travels. Sound is produced by compression and rarefaction of air molecules creating a sound wave. If a sound wave travels through matter such as solid,liquid and gas, it may hit any other object or surface,and the energy of the sound wave travels back and disperses creating an echo. A repetition of an echo results when a sound wave is reflected on surfaces many times depending on its energy.  It is a single reflection from the source of the sound and the time delay is the extra distance divided by the speed of sound (330m/sec). Echos occurs in spaces containing objects for it to be reflected instantly.
