Sonogram of an S19 call, depicting where I measured the fundamental frequency of the tone.
Sonogram of an S1 call, depicting how I measured the call duration. Black lines indicate start and end points of my measurement.
My S19 fundamental frequencies shown varying around Ford’s(1990) S19 average fundamental frequency for the beginning of the tone. Yellow line depicts my S19’s average in comparison to Ford’s average, in red.
My measured S1 fundamental frequencies compared to Ford’s average fundamental frequency for an adult S1 call.
Call duration of my S1’s compared to average call duration of Ford’s S1’s.
Ishmael located call at 173 and 187 degrees.
