Sound and Music Question Title * 1. Please enter your name: Question Title * 2. Group: Question Title * 3. What makes sound? Something vibrating Sound waves Two objects moving in the same direction Two objects moving towards one another Question Title * 4. When you talk, sound travels through the air as moisture from your mouth to the listener's ear air currents from your mouth to the listener's ear dust particles from your mouth to the listener's ear waves moving through the air from your mouth to the listener's ear as particles from your mouth to the listener’s ear Question Title * 5. The energy of sound waves is always very small and can only be detected by our ears or other sensitive instruments True False Question Title * 6. Which of the following is NOT a cause of vibration for musical instruments? plucking a string buzzing your lips pressing a key on a flute sliding a bow on a violin Question Title * 7. When an object is made to vibrate at its natural frequency of vibration, we say the object is in resonance in pitch in harmony in the cochlea at wavelength Question Title * 8. What causes a tuba to have lower sounds than a trumpet? the large bell the sound comes out of the fat tubes the sound waves move through before coming out the long distance the sound waves have to travel before they get out the way the musician blows into the tuba Question Title Question Title * 9. A violin is basically a hollow wooden box with strings across it. If the wooden box were replaced by a solid piece of wood, the violin would sound the same higher lower louder quiter Question Title Question Title * 10. The organ pipe shown in the diagram produces a certain musical pitch. Which of the other four organ pipes shown would produce the same pitch? A B C D Question Title * 11. If a person blows over the top of the pipes shown in the diagram, which pipe will make a lower sound? A B D Both C & D Both B & D Question Title * 12. Low pitch is a quiet sound a low sound (bass) a loud sound a high sound (treble) Question Title * 13. The pitch of sound depends on the frequency of the sound loudness of the sound speed of the sound Question Title * 14. Treble notes are high on the musical scale. The vibrations producing treble notes have low frequencies (vibrate less often per second) high frequencies (vibrate more often per second) The note does not depend on the rate of vibrations (# per second) Question Title * 15. Humans can hear sound with wavelengths that range from half an inch and to 50 feet. Bass notes are low on the musical scale and have longer wavelengths shorter wavelengths The note does not depend on the length of the wave Question Title * 16. What part of the ear is used to collect and funnel sound down the ear canal? Eardrum Pinna Cochlea Ossicles Question Title Question Title * 17. If all the waves shown above are shown for equal lengths of time,Which of the options has a larger amplitude than the original wave? A B C D E Question Title * 18. If all the waves shown above are shown for equal lengths of time,Which of the options has a larger frequency than the original wave? A B C D E Question Title Question Title * 19. Which distance, labeled above, is equal to one wavelength A B C A & B B & C Question Title * 20. Hair cells in different parts of the cochlea respond to different frequencies Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 21. Sound waves hit the eardrum and cause it to vibrate Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 22. The vibrations continue through the ossicles in the middle ear and travel to the cochlea Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 23. Sound that is too loud can damage the tiny hair cells of the inner ear. Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 24. The hair cells turn the vibrations into electrical signals that are sent to the brain. Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 25. Being around loud sounds a lot will help your ears get used to it and protect your hearing. Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 26. The more time I spend around loud sound, the worse my hearing will be. Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 27. Hair cells in the cochlea can be fixed after being damaged by loud sounds. Strongly agree Agree Don't know Disagree Strongly disagree Question Title * 28. Please describe what the general characteristics of musical instruments are. How do they make sound? change pitch? amplify sound? Question Title * 29. What determines the natural frequency in each of the following instruments? Straw instrument cup instrument your voice acoustic guitar electric guitar piano Question Title * 30. Consider how each of the following instruments amplify sound. What makes them loud? For each instrument provide three things: 1. Is the mechanism resonance or sympathetic vibration, 2. What part of the instrument makes it loud, 3. Why do you think this? straw instrument cup instrument your voice acoustic guitar electric guitar piano Done
