Pipe noises
If no check valve is in place to keep the house water from back-feeding into the public water supply, what you are most likely hearing, especially during the Summer months, is the water pressure dropping due to Hydrant testing, and especially in a business district, due to people using the public water supply. Contact your utility and see if they can monitor the water pressure on your home, and check for any leaks, since infrastructures are getting worst now that cities are deferring maintenance until the line breaks somewhere.
Also, update with your location, so others know where you are to better help you.
