Final answer:
When planning a noise survey, it is important to measure the sound intensity, frequency, duration, location, and sources of the noise. These measurements will provide data on the noise levels and characteristics, which can be used to analyze the impact of the noise and develop strategies for reducing it.
Step-by-step explanation:
When planning a noise survey, there are several things that should be measured:
- The sound intensity, which can be measured using a decibel meter. This will give you an idea of how loud the noise is.
- The frequency of the noise, which can be measured using a frequency analyzer. This will tell you the pitch of the noise.
- The duration of the noise, which can be measured using a stopwatch. This will tell you how long the noise lasts.
- The location of the noise, which can be marked on a map to identify areas with high levels of noise.
- The sources of the noise, which can be identified through observation and interviews with people in the area.
By measuring these factors, you can gather data on the noise levels and characteristics in a given area, which can then be used to analyze the impact of the noise and develop strategies for reducing it.
