Study Notes
Sound Propagation
- Sound primarily propagates through a medium, which can be solid, liquid, or gas; air is the most common medium for everyday sound transmission.
Speed of Sound
- The speed of sound in air at a temperature of 20°C is approximately 343 meters per second (m/s).
Factors Affecting Sound Speed
- Various factors influence the speed of sound, including temperature, density, and elasticity of the medium; however, humidity does not significantly impact sound speed.
Sound Intensity Measurement
- The intensity of sound is measured in decibels (dB), which quantify the pressure level of sound relative to a reference level.
