  • Sound Intensity
    A measure of the power carried by a sound wave per unit area.
  • Power
    The rate at which energy is transferred by a sound wave.
  • Surface Area
    The area over which a sound wave spreads, affecting its intensity.
  • Isotropic Emission
    Sound emission that is uniform in all directions.
  • Sphere
    A 3D shape used to model the spread of sound waves from a point source.
  • Intensity Level
    A logarithmic measure of sound intensity, related to perceived volume.
  • Decibel
    A unit used to express intensity level, denoted as dB.
  • Threshold of Hearing
    The quietest sound that can be heard by the average human ear, 0 dB.
  • Logarithmic Scale
    A scale used for intensity level, where each step represents a tenfold change.
  • Pressure
    The force exerted by a sound wave per unit area.
  • Density
    The mass per unit volume of a medium through which sound travels.
  • Speed of Sound
    The speed at which sound waves propagate through a medium.
  • Frequency
    The number of oscillations of a sound wave per second, measured in hertz.
  • Volume
    The perceived loudness of a sound, related to intensity level.
  • Atmospheric Pressure
    The pressure exerted by the weight of the atmosphere, approximately 101,325 Pa.
