Fig. 3 - Sons com timbres diferentes

porque os sons apresentam timbres diferentes.

O timbre de uma fonte sonora é representado por uma ondacomplexa, que é a soma de uma onda fundamental (som puro, ousimples, como o produzido por um diapasão) e sons harmónicos.

Cada fonte sonora produz uma onda sonora complexa diferente(a onda produzida por uma viola é diferente daquela que produzuma flauta).

Duração

Representa simplesmente o tempo que o som dura. Geralmente mede-se em segundos (unidade do sistemainternacional).
