T/I111. What further aspects of waves and sound and their applications would you like to know more about? T/IResearch112. Research the 1929 Grand Banks earthquake and tsunami. Prepare a visual presentation. Provideobservations of eyewitness or newspaper accounts contemporary with the actual events. Contrast these reports with more recent scientific explanations in terms of seismic wave activity and landslides. T/ICGO TO NELSON SCIENCENEL496 Unit 4 • Waves and Sound
113. Investigate the criteria for acceptable levels of noise at the federal and provincial levels. Consult information provided by the Canadian Centre of Occupational Health and Safety. Prepare a brief presentationexplaining criteria levels and exchange rates. Include some sound samples. Discuss the implications of standards on particular types of occupational or recreational noise. T/IC114. Investigate the mathematical relationship between sound intensity and loudness. Prepare a briefpresentation explaining this relationship. Pose and solvesome problems illustrating this relationship. T/IC115. The Bay of Fundy is legendary for its high tides. Find out what tidal resonance means. Which body of water holds the world’s record for the highest tides? Write a short report about your findings. T/IC116. The Canadian composer R. Murray Schafer introduced the idea of sound ecology in his World Soundscape Project. Research his work on soundsin the environment and noise pollution. Listen to a recording of the Vancouver Soundscape. Prepare abrief podcast discussing the history of this project and the role it has played in promoting acoustic technology and sound legislation. T/IC117. Ultrasound stethoscopes make use of the Doppler effect. As a result, these stethoscopes are more effective than traditional stethoscopes in noisy environments. Prepare a brief report on howultrasound stethoscopes make use of the Doppler effect. T/IC118. Sound therapy is said to have a healing effect on both the creator of the sound and the listener. Research sound therapy, and make a brief presentation on sound therapy with instruments such as the didgeridoo. Include audio clips if possible. T/IC119. Find out and explain how research on bat echolocation has been applied to robotics. T/IC120. Scales provide a palette of tones for melodies and harmonies to someone writing and playing music. The scales are based on relationships between the frequencies of successive tones. Prepare a briefpresentation contrasting the frequencies and wavelengths of the notes in a musical major scale and its related minor scale. Compare and contrast the tones in these two scales. C121. The production of human sounds depends on the regulation of airflow through the lungs, throat, nose, and mouth. This airflow is altered in various ways by systems involving the lungs, trachea, voice box, and oral and nasal cavities. Investigate the production and frequencies of men’s and women’s voices. Prepare a briefreport on the physiology and physics of speech.
