As I open a bottle of carbonated water, and lets out a distinctive whistling sound. where, in this spectrogram, would the whistling sound likely have occurred? A. 0.1 secs
B. 0.4 secs
C. 0.55 secs
D. 1.1 secs

Option D

1.1 seconds

Explanation:

The whistling sound has a high frequency and a high pitch. This is usually represented by a spike in the frequency-time graph.

The spectrogram is able to show this point on the graph it plots. This will be a point that has the waveforms clustered together as well as increased. These are points of high frequency, as well as pitch.

From the spectrogram, such a point occurs at point D.  at 1.1 seconds.
