Midterm Study Tips
For our midterm exam, it is STRONGLY recommended that you study the lecture notes and video notes thoroughly, as most of the questions will be taken from these notes.
The exam will contain 53 multiple choice questions, each worth 0.5 point for a possible total of
26.5 points towards your total point accumulation. Since the final exam is officially worth 25% of your grade, you have the chance to earn 1.5% of extra credit.
The 53 questions will be based on the following materials:
48 Qs from Note 1 (Introduction to Animal Communication) through Note 9 (Evolution of
Human Language).
5 Qs from the videos
Great Transformation and
Signals and Songs

Sample Questions
Acoustics (Notes 2 & 3)
1) Are sound waves in air longitudinal or transverse waves? Longitudinal longitudinal waves are simple and periodic can equate frequency (F) transverse waves are complex and aperiodic fundamental frequency (F0) 2) What is the approximate speed of sound in air (that we use in this class)? 350 m/s 3) What is the frequency of the simple sound wave above?
F= 1/t t= time / # of cycles 4) What representation of sound is illustrated above?
Waveform
xtime ypressure Spectrogram xtime yfrequency
Spectrum
(Another way of asking the same question: How the above representation of sound called?) 5) What is plotted on the x axis on the figure above?
Frequency x
Amplitude y 6) What is the fundamental frequency (F0) of the complex sound wave above?
.03 / 3 = .01 1/.01 + 100Hz
7) Intensity of a sound is the physical basis of perceived ____ loudness ____ of that sound.
(Fill in the blank.) 8) F0 of a complex sound is the physical basis of perceived _____ perceived pitch
_____ of that sound. (Fill in the blank.) 9) What are the three physical properties that are shown in sound spectrograms?
Intensity, frequency,
