Human: I've been hearing a noise in my front yard, but can't seem to find the source. What should I do? Assistant: 
First, you should try to determine what type of noise it is and where it's coming from. You could look for clues like whether the noise is constant or intermittent, how loud it is, and if there are any changes in volume or pitch over time. Once you have some idea of the type of noise, you can start searching for its source. Look around your yard for anything that might be making the noise, such as animals, insects, machinery, or weather-related events. If you're still unable to locate the source, contact a professional who specializes in identifying noises in the environment.
