What factors determine the loudness of a sound?
The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater.
How do you calculate loudness of sound?
It is defined as dB = 10 * log10(P 1/P 2), where P1 and P2 are the relative powers of the sound. phon: A unit of apparent loudness, equal in number to the intensity in decibels of a 1,000-hertz tone judged to be as loud as the sound being measured.
What does the pitch of a sound depend on?
Pitch depends to a lesser degree on the sound pressure level (loudness, volume) of the tone, especially at frequencies below 1,000 Hz and above 2,000 Hz. The pitch of lower tones gets lower as sound pressure increases.
On which factors sound depends on?
What are the factors on which sound depends?
- Density of the medium-the speed of sound is inversely proportional to the density of the medium.
- Humidity of the medium-More humid the air is,greater is the speed of sound.
- Temperature of the medium-The speed of sound is directly prop.
Loudness of sound. This phenomena of a sound depends on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud. It is directly proportional to the square of the amplitude of vibration. If the amplitude of sound wave becomes double, then the loudness of the sound will be quadrupled.
What makes a Sound said to be loud?
Loudness of sound. This phenomena of a sound depends on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud.
How are pitch and loudness of sound the same?
The pitch of a sound is dependent on the frequency while the loudness of a sound depends on the amplitude of sound waves. These two phenomena are considered to be the same sometimes, but they are not the same. They both differ based on tone quality Whereas loudness is dependent on the energy of the wave.
Which is the best description of the characteristics of sound?
Ans: Characteristics of sound are Pitch, Loudness, and Quality. Pitch: It is based on the frequency of the sound wave. A note has a lower pitch when the frequency is low, and a note of a higher frequency has a high pitch. The word ‘pitch’ is frequently used in music.
