1. The speed of sound in a medium depends primarily on the density and elasticity of the medium. Higher density and greater elasticity lead to faster sound propagation, while lower density and elasticity result in slower speed.

  2. We may perceive one sound as louder than another of equal intensity due to differences in frequency, duration, or spectral content. Additionally, psychoacoustic factors such as auditory masking and individual sensitivity can influence perceived loudness.

  3. No, loudness and intensity are not interchangeable terms. Intensity refers to the amount of energy per unit area carried by a sound wave, while loudness is the subjective perception of the intensity by the human auditory system.

  4. The intensity of sound refers to the amount of energy carried by sound waves per unit area perpendicular to the direction of wave propagation, measured in watts per square meter (W/m²).

  5. In a given medium, the speed of sound remains relatively constant regardless of frequency. However, the medium's properties, such as temperature, density, and elasticity, can influence the speed of sound, but these factors typically affect all frequencies similarly.
