Answer:

1.how is an echo produced:

An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound. ... But sounds are not always reflected.

2.Timbre is defined as the characteristic quality of tone that makes two voices or sounds different. An example of timbre is the warm tone of Nat King Cole's voice. ... A quality of sound that distinguishes one voice or musical instrument from another.
