how we can diffrenitiate between two sound that have same pitch and frequency
Answers
It’s because there are more than one frequency (pitch) present. For instance, when a clarinet plays note such as an A, you perceive the A as the pitch, but there are a whole series of other “notes” going on at the same time. They are all higher in pitch than the A which you are hearing, and your personal hearing system (ear) is very good at detecting these pitches. They are known as Harmonics, which are a very specific series of frequencies which are always present, with the one exception of a sine wave, which doesn’t exist naturally, but we can produce them with things like tone generators. If you were to hear two sine tones at the same time, which were the same volume, pitch, and in phase with each other, you wouldn't be able to distinguish them from one another. The only perceptible difference would be a 3dBspl increase in volume, due to the doubling on energy in the air.
The harmonic frequencies which are always present very in their respective levels, and phase relationships. Even if the difference is minimal most people’s ears can detect them. Most people can tell the difference in tone between Louis Armstrong’s trumpet and Wynton Marsalis’ trumpet, not to mention a violin coming in with the same pitch.
Hope this helps you...
Answer:
Imagine that a singer sings the same note twice, one an octave above the other. You can hear a difference between these two sounds. That is because their pitch is different. Pitch depends on the frequency of a sound wave.
