Before we take action, though, we need to know how bad the problem really is. Another reason we chose it is because we could take real measurements with an actual piece of scientific equipment. We could actually prove our point to an audience. Next, there is more and more noise, and something needs to be done about it. We thought that people needed to know about the dangers of loud noise.
Many people are ignorant, especially teenagers.
And finally, we didn't know about the dangers of loud noise and sound, but we wanted to know about it. We actually decided on this topic by making a master list of other topics, and then drawing a decision-making matrix. We evaluated each of our topic choices, rating them on a scale from 1-5 for various criteria. Some of the criteria were interest level, information available, and the possibility of a real product at the end. We also wanted to learn a different way to do something in the topic we chose.
