For the physics questions illustrated below, answer the following questions in detail in a typed word document, using Times New Roman font all along with citations and references in APA style. You can as well provide examples wherever required. Problem 1: Illustrate the differences between sound power, sound intensity and sound pressure. Problem 2: What range of frequencies can humans listen to? Problem 3: Recognize the main sources of environmental noise. Problem 4: What reference pressure is employed in finding out sound pressure levels? Problem 5: Illustrate the relationship between sound pressure and distance from the source. If the distance is twice, determine the difference in the sound pressure levels in decibels? Problem 6: Determine weighting scales? Explain why are they utilized? Problem 7: Most of the environmental noise measurements are made by employing a Type II meter. Determine Type II meter?
