Superposition of waves: The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the similar time. When two sound waves cross at the same time…

Noise and Musical Sound and their Effect We hear different sounds around us. For examples, the pattering sound of rainfall, tone of violin, note of guitar etc. are pleasant and we enjoy to listen to…

Meaningful sounds that we hear originate due to the combination of many frequencies. If these frequencies are mutually simple multiple, then resultant sound produced by these frequencies becomes musical sound. But if there is no…

Musical Interval or Musical Proportion Most of the meaningful words which we hear are composed of different frequencies. This frequency, being the simple multiple of one other, appears to us musical in character. The major…

The contribution of Physics in the Analysis of Musical Sound We know the characteristics by which we can distinguish clearly two sounds having same loudness and intensity is called quality. By this characteristic, it can…

Harmonics We know, different tones exist in a music. The tone having lowest frequency in them is called fundamental tone. Other tones whose frequencies are higher than the fundamental tone are called overtones. Again, if…

Musical Scale We know in a tone there exists low and high frequencies. A tone of lowest frequency is called key note. Values of tones of higher frequencies exist at fixed ratio of the key…

Mathematical Expression of Beat Let consider two sounded tuning forks having frequencies n1 and n2 (n1> n2) and the difference between the two frequencies is not large. Furthermore, let us consider that incoming sound waves…

Application of Beats When two sound waves of equal or nearly equal intensity and nearly equal frequencies originate at the same time and travel along the same direction, the loudness of the resulting sound is…

Mechanism of Formation of Beats When two sound waves of nearly equal frequencies originate at the same time and travel along the same direction, meet a particle of the medium, the phases of combined tone…
