1.4 Human Voice


Human Voice Recording( Lim Hao Yang Singing)

Tuning Fork recording

Not much in smilarities

The most obvious difference that can be seen is the shape of the wave.
Speech wave patterns are complex,are aperiodic,the amplitude depends on the amount of energy that is channeled during speech,and the range is 85Hz to 11000Hz.
Sound pressure waves are simple,are periodic,and amplitude depends on how hard the tuning fork is hit.
