Sound - Sound Intensity - Episode 207

what's updo it, get to ittake it outside!

How noisy is my world?
tarissa and sabrina We're Tarissa and Sabrina and we're living loud in New York City! As one of the world's noisiest places, it's sometimes hard to hear yourself think in our hometown. For our DragonflyTV investigation, we asked: Just how loud are some of our favorite hang-outs?

How would you investigate this question?
What locations would you measure? How are you going to measure the decibel level of your chosen spots? Of course, you'll also have to determine just how loud is "loud;" research what noise levels are considered safe and which are actually dangerous. When you examine your measurements, are there any surprises, with some places noisier or quieter than you initially thought? Describe your findings in your investigation notebook and discuss them with your teacher, or go to Extreme Sounds to find out more about
the volume of life in the Big Apple.
