Answer 2

What do you mean by quality of sound?

Quality of sound refers to the specific characteristics in sound that helps us to tell the difference in the sound even if they have the same pitch, frequency etc.

For example, even if two people produce sounds of same pitch and frequency, we will be able to distinguish the sound from one another. This characteristic is also known as timbre.

Why it is different in different instruments?​

The quality of sound is different in different instruments due to the following factors:

✳ Difference in wave forms [amplitude]

✳ Difference in materials used to make them

✳ Elasticity

✳ Harmonic characteristics [Harmonic frequencies]

✳ Attack and decay [This refers to the increasing and decreasing of the sound using force on the instrument]

Knowledge Bytes:

⇒ What is sound?

Sound is a form of energy that helps to provide the sensation of hearing.

⇒ What are audible and inaudible sounds?

Those sound waves that we can hear are known as audible sounds. These sounds will have frequencies of 20Hz to 20,000Hz. This doesn't mean that they are the only sounds! Those sounds that have frequencies above 20,000Hz and below 20Hz are known as inaudible sounds. They can be heard by other organisms that have special organs to detect these sound waves.

⇒ What are the characteristics of sound?

The characteristics of sound are loudness, pitch and quality. Even though loudness and pitch is same, we can determine the variations as different sources are used to determine the sound waves.
