Imagine for a moment that treble sounds could travel at 400 m/s, but bass sounds at only 200 m/s. If sound behaved that way, and you were listening to the CU band in Folsom stadium from a distance of 110 m, how much delay would you hear between the trumpet and tuba notes when they begin a chord together?

Question

Imagine for a moment that treble sounds could travel at 400 m/s, but bass sounds at only 200 m/s. If sound behaved that way, and you were listening to the CU band in Folsom stadium from a distance of 110 m, how much delay would you hear between the trumpet and tuba notes when they begin a chord together?

Answer 1

To calculate the delay between the trumpet and tuba notes, we need to determine the time it takes for each sound to reach the listener. In this scenario, treble sounds travel at 400 m/s and bass sounds at 200 m/s. The distance between the listener and the band is 110 m.

Let's break down the calculation for each instrument:

1. Trumpet sound:
The distance between the listener and the trumpet is 110 m. Since treble sounds travel at 400 m/s:
Time taken by the trumpet sound = distance / speed = 110 m / 400 m/s = 0.275 s

2. Tuba sound:
The distance between the listener and the tuba is also 110 m. However, since bass sounds travel at 200 m/s:
Time taken by the tuba sound = distance / speed = 110 m / 200 m/s = 0.55 s

Now, to calculate the delay between the trumpet and tuba notes, we subtract the time taken by the trumpet sound from the time taken by the tuba sound:

Delay = Time taken by tuba sound - Time taken by trumpet sound
= 0.55 s - 0.275 s
= 0.275 s

Therefore, the delay between the trumpet and tuba notes will be 0.275 seconds.

To calculate the delay between the trumpet and tuba notes, we need to determine the time it takes for each sound to reach the listener. In this scenario, treble sounds travel at 400 m/s and bass sounds at 200 m/s. The distance between the listener and the band is 110 m.
