1. The speed of sound increases with the temperature of the medium. Higher temperatures cause molecules to move faster, reducing the time it takes for sound waves to travel through the medium, thereby increasing the speed of sound.

  2. Our perception of sound loudness is influenced by the sound's amplitude, frequency, distance from the source, and the listener's sensitivity. Higher amplitude and closer proximity generally make sounds seem louder, while frequency affects perceived intensity.

  3. Loudness is a subjective perception of sound, influenced by the listener and context, while intensity is an objective measure of sound energy per unit area, quantified in decibels (dB). Loudness depends on intensity but also on frequency and duration.

  4. Yes, two sounds with equal intensity can be perceived differently in loudness due to factors like frequency and the listener's sensitivity. Higher frequencies and individual hearing characteristics can make one sound seem louder than another.

  5. Sounds with frequencies below 20 Hz are called infrasound. Humans cannot typically hear these frequencies, although they may sometimes be felt as vibrations rather than heard as distinct sounds.
