1 Properties of Sound

2 Pitch Loudness Speed in Various Media

3 Pitch, or Tone Pitch is directly related to frequency. Range of Human Hearing 20 Hz – 20,000 Hz Sonic Range

4 Infrasonic Below 20 Hz Above 20,000 Hz Ultrasonic

5 Loudness The human ear is not a linear device. It is logarithmic.

6 Log Graph

7 Decibels The unit of loudness is the decibel, 1/10 of a Bel (named after Alexander Graham Bell)

8 Logarithmic Hearing The decibel scale is logarithmic, which means that an increase of 10 dB is a 10 time increase in intensity.

9 Decibel Equation

10 Intensity

11 Increase in Intensity Intensity Increase

12 Speed of Sound in Media The speed of sound is directly related to the elasticity of a medium. The speed of sound in a medium is indirectly related to the density of the medium.
