Answer:
1.These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
2.Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

4.PITCH means the highness or lowness of the sound.
5.Pitch refers to the location of a musical sound in terms of low or high. As we have seen, in terms of the physics of sound, pitch is determined by frequency, or the number of vibrations per second: the faster a sounding object vibrates, the higher its pitch
6.about 20 Hz to 20 kHz
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.
7.We measure sound intensity also referred to as sound power or sound pressure in units called decibels.
8.Frequencies above 20,000 Hz are known as ultrasound
9.At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound
10.
11.decibels (dB)
12.Decibels
13.20 to 20,000 Hz
The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
14.THRESHOLD OF PAIN
The INTENSITY LEVEL of a loud sound which gives pain to the ear, usually between 115 and 140 dB (see graph). For some listeners with HYPERACUSIS these levels may be much lower. At lower levels occur the threshold of feeling (or tickle) and the threshold of discomfort.
15.Misophonia, meaning "hatred of sound", is a proposed neurological condition in which certain sounds trigger emotional or physiological responses others may deem unreasonable
16.
17.The amplitude of a sound determines its volume (loudness). Tone is a measure of the quality of a sound wave. Sound travels faster in a hot medium , or in a solid. It also travels faster at sea level (where air pressure is higher)
18.cochlea
19. In physiology, sound is produced when an object's vibrations move through a medium until they enter the human eardrum. In physics, sound is produced in the form of a pressure wave.
20.These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
