उत्तर
The two sounds of the same loudness and pitch produced by different instruments differ due to their different waveforms.
The waveforms depend on the number of the subsidiary notes and their relative amplitude along with the principal note.
The diagram below shows the wave patterns of two sounds of the same loudness and pitch emitted by two different instruments. They produce different sensations in the ears because they differ in waveforms: one is a sine wave, while the other is a triangular wave.
