If you are getting a humming noise then you probably have an earth loop. This is where the resistance from one piece of equipment has a higher resistance than on other piece that it is connected to. The current flows through the lower resistance piece of equipment back to the earth on the mains causing the hum.
There are two ways to cure this. the method used by recording studios is to create a star Earth. This is where all the earths from all devices comes back to a central earth point then to the mains earth.
The alternative method is to break the shield at one end on the patch lead that goes from each device to interrupt the mains loop and force the earth current to run back down the mains cable earth.
I assume you mean hot, neutral and ground. The answer is simple...the advantage is life or death in a home wiring situation. The only true job of electricity is to seek ground and it will find it through the path of least resistance. If the neutral wire of a 110v 2 wire system becomes open, the only path to ground may be your body. If that same wire opens on a 3 wire grounding system, there is a backup path through the ground wire creating a low resistance to ground. Safety issue.

An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.
All ground wires are green or green yellow marker.
The intercom system is a communication system. You need a electric circuit, transistors and the door bells to assemble it at home.
You can make music anywhere. If you wanted to record it you can get a home recording system.
When choosing a studio sound system for home recording, look for features like high-quality speakers, a versatile audio interface, low latency, compatibility with your recording software, and adjustable settings for optimal sound control.
A surveillance system is a series of video camera or cameras and recording devices. They are used to monitor the security of a home or other property.
Video Home System, better known as VHS, is a video tape recording standard developed during the 1970s.
Home Recording Rights Coalition was created in 1981.

It increases some if it is a good system. You need a recording good enough to identify the people.

There are different types of recording systems, analog and digital. Recording systems allows you to record a subject and then play it back. It can also be a system of documenting facts or events.
For a home recording studio, I recommend a high-quality condenser microphone paired with a USB audio interface and studio monitors for accurate sound reproduction. This setup will provide clear and professional sound quality for singing recordings.
Peavey makes a great mixer to use for home recording.
Cubase is better for the beginner. ProTools is not considered a "home" recording solutions. Try the simpler version of Cubase, Cubase Essentials.
