  1. A sound wave is usually characterized by the power (energy / second) it carries: the intensity is the power (P) divided by the area (A) the sound power passes through: The human ear can detect sound of very low intensity. The smallest detectable sound intensity, known as the threshold of hearing, is .
  2. A sound wave is a longitudinal wave and since the displacement of the wave causes a amplitudes of the waves considered separately. These areas are called anti-nodes. Such a This part of the experiment will use “Sound stoneshaperfelharimhelldweller.xyzinfo” that can be downloadedfromthelab’swebsitealso.
  3. 5. Did the experiment prove or disprove your hypothesis? Support your conclusion based on results from the experiment and your knowledge of sound waves. The experiment proved my hypothesis because whenever the sound gets closer to the observer, it increases and whenever it passes him, it decreases. These are sound waves. 6.
  4. Sound requires a matter through which to travel. The matter is called the medium of a sound. A medium can be a solid, liquid or a gas. Sound cannot travel through empty space.
  5. Sound Waves 1. In an experiment for measuring the speed of sound, a gun was shot m away from the observer. It was heard seconds after the flash was seen. What was the speed of sound in air at that time? (Hint: velocity = distance/time.) 2. Sound travels .
  6. Echoing Sound! Experiment: To bounce sound! Materials: You will need-Two pieces of tracing paper. One plate Cork Several books A ticking watch Two cardboard tubes A friend Method: What you have to do-1) Build two piles of books, they must be the same height. 2) Carefully lay the tubes on the books as shown above. 3) Hold the watch to your ear.
  7. This science experiment is fun and easy to do. It is designed to teach kids how sound travels from one end to another. With the help of a long string and two plastic cups, kids will learn to create their own working telephone. They will have fun carrying out this activity as they learn how sound waves are created and how sound travels through air.
  8. The sound would then measure 30 dBIL (10 log10 1, = 10 (3) = 30 dBIL). Now suppose that we put the sound intensity meter away and use a sound pressure meter to measure the same sound. You might think that the sound would measure 60 dBSPL since now we are multiplying by 20 instead of 10, but the trick is that the ratio is no longer 1,
