This document compares two sound samples, with sample 1 being a low, loud sound around 600Hz while sample 2 is a high pitched sound at 1200Hz. The waveforms are shown with sample 1 having a wider amplitude, indicating it is louder than sample 2.

Estimate of frequency (Hz) 6 x 100 = 600Hz Estimate of Frequency (Hz) 12 x 100 = 1200Hz
Sample 1 is louder than sample 2 (wider amplitude).
