PREFACE This instructor’s manual and test bank is designed to accompany the third edition of Speech Science: An Integrated Approach to Theory and Clinical Practice. The purpose of this manual is to provide instructional and testing material to support classroom lectures. Suggestions for teaching methods are offered, but may be adjusted according to each instructor’s preference of style and key emphases. Each chapter provides the following: (1) a chapter overview; (2) key concepts; (3) a list of emphases; (4) suggested discussion topics and instructional activities; (5) test bank. The test bank includes multiple choice questions, true-false questions, short answer questions, and essay questions. The answer key for multiple choice and true-false questions is provided at the end of the manual. CHAPTER OVERVIEW AND SUMMARY The chapter overview and narrative summary provide a guideline that the instructor can use to construct class lectures, or to determine which information he or she would like to focus on. Information presented in these sections may also be provided to students in order to familiarize them with material that will be introduced, and give them a foundation for the upcoming concepts. KEY CONCEPTS The key concepts focus attention on important material covered in each chapter. These pages may be photo-copied and distributed to students. Instructors may provide the key concepts at the beginning of a chapter, prompting students to complete the definitions. This allows students to become familiar with the information and helps to develop a framework to follow the instructor’s presentation of the material. Instructors may also choose to provide the concepts before an exam, as a means of reviewing information. Additionally, key concepts may be used as pre- and post-tests to assess student knowledge. EMPHASES AND INSTRUCTIONAL ACTIVITIES This section offers suggestions for topics to be introduced and discussed by the instructor. Some ideas for manner of presentation are included, such as using graphs, charts, or diagrams to acquaint students with more complex information. Within each section there are various discussion topics and instructional activities that may be used to demonstrate more elusive concepts and further support classroom lectures. TEST BANK A series of test questions are presented at the conclusion of each chapter. Instructors may select specific questions as a supplement to their own prepared examination, distribute the test bank in its entirety, or use the test bank as a general review before administering their own examination.

EMPHASES AND INSTRUCTIONAL ACTIVITIES 1. Review basic terms and concepts, such as mass, density, volume, pressure, etc. 2. Explain the relationship between air pressure and sound. 3. Students will understand the power of air pressure as well as changes in pressure with this simple demonstration. Use a peeled hard-boiled egg, a jar with an opening that is slightly smaller than the diameter of the egg, a piece of paper and a lighter. Light the piece of paper and drop it into the bottle. Place the hard-boiled egg on the opening of the bottle. Increasing the temperature of air inside the bottle increases the pressure. Once the flame goes out, the pressure inside the bottle decreases relative to atmospheric pressure, and the positive atmospheric pressure pushes the egg into the bottle. 4. Describe simple harmonic motion (SHM), frequency, period, wavelength, velocity and amplitude. 5. Simple harmonic motion, frequency, and amplitude can be shown by using strings of different lengths with hex nuts attached to one end of each string. When swung the string acts like a pendulum, and makes it easy for students to visualize the smooth back and forth motion that is characteristic of SHM, as well as the relationship between frequency and amplitude. 6. You can also demonstrate simple harmonic motion by using a hanging spring with a mass attached to the end. As you pull the mass down and release it, the spring will continue to move up and down in a repetitive motion. This will continue until the motion gradually fades away. On page 16 of the text, an illustration demonstrates what would occur if a marker was attached to the spring as it moves up and down. 7. Frequency, amplitude, and constructive/destructive interference can be demonstrated using a long slinky. Have two students stand across from one another with a slinky placed on a table between them. One student gives the slinky a push, generating a wave that travels along the length of the slinky. Pushing the slinky more forcefully increases the amplitude; pushing it more quickly increases the frequency. When the students push the slinky at either end, waves are generated from each end and travel toward each other. These waves will interfere either constructively, increasing the amplitude, or destructively, decreasing the amplitude. 8. Introduce pure tones versus complex sounds and waveforms versus spectra. Discuss the types of information that can be obtained from each type of graph. Prepare a variety of waveforms and spectra of pure tones and complex periodic and aperiodic sounds and have students interpret the graphs in terms of their perceptual and acoustic characteristics. 9. Describe the decibel scale and its relevance to an audiogram.

10. Many apps are available that analyze frequency and amplitude. Students can download these onto their smartphones or tablets and they provide a fun and easy way of becoming familiar with these concepts. CHAPTER ONE TEST BANK MULTIPLE CHOICE QUESTIONS 1.

EMPHASES AND INSTRUCTIONAL ACTIVITIES 1. Introduce the difference between free and forced vibration. Explain that forced vibration is the basis of resonance. You can easily demonstrate forced vibration by placing a radio on a light table. Turn up the volume to a moderate level and have students feel the table. Increase the volume while the students continue to feel the table. Have the students think about the table’s vibration in terms of natural frequency, free vibration, forced vibration and driving frequency. 2. Discuss acoustic resonance and tube resonance. 3. Explain the filtering properties of acoustic resonators. You can use the common experience of holding a seashell to the ear and hearing “the sound of the sea” as an example of acoustic resonance. There is always background noise present even in a very quiet room. This noise is composed of low intensity sound waves with a broad range of frequencies. The background noise creates vibrations within the shell. As with any air-filled container, the seashell has a natural frequency or frequencies at which it will vibrate with greatest amplitude. Some of the frequencies in the room (applied frequencies) are likely to be close to the natural frequencies of the shell, creating constructive interference and causing those frequencies to become audible when the shell is held close to the ear. 4.

Introduce vocal tract resonance, listing the characteristics of the vocal tract in its role as an acoustic resonator. 6. Describe the source-filter theory.

Discuss F1/F2 plots, noting the relationship between the articulation of the corner vowels and their acoustic correlates.
