Study Notes
Sound and Sound Intensity
- Sound refers to a form of energy that is transmitted through vibrations
- Sound intensity is the amount of energy transmitted per unit area per unit time
- Decibel (dB) is the unit used to measure sound intensity
- Associated terms include frequency, amplitude, wavelength, and speed
Classification of Sound
- Sound can be classified into different types, including musical sounds
- Musical sounds have specific characteristics, including pitch, tone, and timbre
Calculating Sound Intensity
- Sound intensity can be calculated using the formula: intensity = power / area
- Intensity level of sound is the ratio of the intensity of the sound to a reference intensity, usually expressed in decibels (dB)
