Musicians do their best to sing, play, produce sound waves that are in tune. When in tune, the sound sounds significantly louder than when it is not in tune. Which choice below best explains why this happens?
a)
When musicians are in tune, they are all producing the coherent (in phase) waves that constructively interfere with each other, resulting in a louder sound than if the musicians were playing individually.
b)
When the musicians are in tune, they aer making sure the beat frequency of the tones they are playing are countering each other, resulting in a smoother, louder sound.
c)
When playing in tune, the musicians are effectively interfering with the outside sound and causing the outside wavelngths to be destroyed, which makes what they are playing louder.
d)
It has nothing to do with what they are playing, and everything to do with the listener's ears perfering in tune sound. The listener's brain amplifies the pleasant sounds, while actively dampening the unpleasant, dissonant sounds.
60.
When listening to a musical group, sometimes the sound you hear sounds wavy, or wobbly, making a wah wah sound even though the musicians aren't actually changing note or pitch. What is going on?
a)
The musicians are in tune, and so the frequencies of sound you are hearing a resonating with your body, making you feel the sound waves.
b)
The individual musicians are playing just slightly different frequencies. these frequencies are interfering with each other resulting in loud and soft spots that we experience as beats or a wah wah sound.
c)
The local movements and temperatures of the air are causing the sound waves to diffract before they reach your ear. the different diffracted waves hit your ear and slightly different times, resulting in louder and softer spot or the wah wah sound.
