Question

What are the characteristics of sound? What factors affect the characteristics of sound? ​

Answer 1

Explanation:

Characteristics:-

Sound produced by any means has the following characteristics, namely, loudness, pitch or shrillness, and quality or timbre. The loudness of sound depends on its amplitude

• Loudness ∝ (Amplitude)2
• Loudness ∝ 1/(Distance)2
• Loudness depends on the surface area of the vibrating body.
• The larger the vibrating area the louder the sound heard.
• Loudness depends on the density of the medium.
• More the density of medium more is the loudness.

Answer 2

Characteristics of sound and factors affecting the characteristics of sound are explained below:

• When waves propagate of frequency in the range of audible sound then we can hear sound.
• The characteristics of a sound wave are amplitude, frequency, velocity, wavelength, pitch, quality, and period.
• Wavelength is the distance between two consecutive rarefactions or consecutive compression or the distance traveled by a wave before it repeats the same distance.
• Frequency is the number of waves that can travel per second or minute.
• The velocity of the wave is the distance traveled by the wave per unit of time.
• The factors which affect the sound are the distance of the source from the person, the amplitude of the wave, the surface area of the vibrating object, the density of the medium, and the presence of resonant objects.
