Purpose:Illustrate the effect on the ear of successive changes of exactly 10 dB.
Description:Setting the generator to a sine wave in the 100-1000 Hz region, the intensity can be changed up and down by 10 dB steps, covering about a 50dB range. Be careful not to exceed the maximum of either the loudspeakers or your ears.
Invite students to compare their experience of different levels to phenomena they are familiar with, such as conversations and concerts.
