state 3 characteristics of musical sound.on what factor do they depend?
Asked by | 19 Mar, 2014, 11:00: AM
answered-by-expert Expert Answer
The characteristics of musical sound are:
1.Pitch - the higness or lowness of sound
2.Intensity - the loudness or softness of a musical sound
3.Timbre/Tone color - the distinctive tonal quality of the producing musical instrument.
Pitch depends upon the frequency of vibration.The higher the frequency of vibration, the higher the tone.
The intensity or loudness of a sound depends on the amplitude of vibration.
Quality is dependent on the number and relative intensity of overtones produced by the vibrating body, and these in turn depend upon the nature of the vibrating body

(3 X 3 = 9) CASE STUDY QUESTION 26. Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components that are generally used in construction of big structures like buildings, machines and also scientific equipment. The cracks or holes inside metal blocks, which are invisible from outside, reduce the strength of the structure. Ultrasonic waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of flaw or defect. Clearly indicated in the figure Defect or flaw Ultrasound Detectors Metal Block (a) The transmitter sends an ultrasound wave of speed 5960m/s through a long steel bridge and a block reflects it back after 0.02s. how far the block in the metal bridge is from the transmitter. (b) With the above property of ultrasound waves, Can ultrasonic waves be used in the medical field? If so, how and give one use in the medical field to justify your answer? (c) Give two practical applications of reflection of sound waves?
