Answer 1

this is ur answer

a) pitch: the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

b) loudness : the pressure level of sound is known as loudness

c) quality of sound: Sound "quality" or "timbre" describes those characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness. ... Timbre is mainly determined by the harmonic content of a sound and the dynamic characteristics of the sound such as vibrato and the attack-decay envelope of the sound.

It's faster than the speed of sound, it's supersonic! Seriously. ... Originally, the word supersonic meant "having to do with sound waves beyond human hearing," but by 1934 it described movement exceeding the speed of sound, with ultrasonic taking on the old meaning. Sonic comes from the Latin sonus, or "sound.

Answer 2

Answer:

The sound that we hear around us is the type of energy made by the vibration that travels through the air or any other medium and can be heard when it reaches a person’s ear.  So, basically sound helps us to communicate with the other person. For example, we can hear the musical instruments like tabla, flute, a guitar due to vibration. The characteristics of sound are as follows:

Pitch: Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies.

Loudness: Loudness is the subjective perception of sound pressure. More formally, it is defined as, "That attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud."

Quality: Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device.

Supersonic Sound:

Supersonic describes things that can travel faster than the speed of sound, like the passenger jet Concorde that used to zip from New York to London in under four hours. Anything supersonic is so fast that you see it before you hear
