Logarithmic scale: dB scale

Logarithmic scale: dB scale

This time, we will bridge the gap between physics and mathematics by studying another application of logarithmic functions. We will learn about the dB Scale and explore how this logarithmic scale can be used to compare the loudness of sounds.

Notes:
dB scale (loudness of sounds)
I1I2=10(dB1dB210) {{I_1}\over{I_2}} = 10 ^ {({{dB_1 - dB_2}\over10})}
