Answer the following:
(a) Name and explain the four factors which affect the
loudness of sound.
(b) What is pitch? Give and explain 3 ways of changing
pitch in different musical instruments.
(c) Give the relation between the following pair of
quantities:
(i) Loudness and amplitude
(ii) Frequency and time period
Answers
Answer:
a)Loudness of sound depends on amplitude, intensity of sound, and sensitivity of the ear
b)Pitch means to throw something. An example of pitch is a baseball being tossed at a bat. ... Pitch is defined as to set something up. An example of pitch is putting up a tent.There are three parameters that effect the pitch or frequency f, that a string makes: the tension T, the length L, and the mass per unit length of the string, lambda.
c)1)Sound amplitude causes a sound's loudness and intensity. The bigger the amplitude is, the louder and more intense the sound.
2)The number of times a cycle is completed in a second is the frequency. The time taken to complete one vibration is called time period. Frequency and time period is inversely proportional, the number of vibrations per second is frequency.
