Sound energy is useful because it allows us to communicate, listen to music, and be aware of our surroundings. It is also important in various industries such as entertainment, healthcare, and security systems. Sound energy can be harnessed to convey information, create ambiance, and detect potential dangers.
The sound energy produced from a car coming to a screeching halt is not a useful form of energy, as it represents energy lost in the conversion process. In this case, the kinetic energy of the car is being converted into both heat and sound energy, which are typically considered wasted energy.
The useful energy in a whistle is the sound energy produced when air is forced through a small opening, creating vibrations that travel as sound waves through the air. The pitch and volume of the sound are determined by the size and shape of the whistle.
The useful energy in a radio is the electrical energy converted into radio waves that transmit sound through speakers, allowing us to listen to music or news.
A useful change in headphones is the conversion of electrical energy from the audio device into sound energy that we can hear. The energy transformation that occurs in headphones involves converting electrical signals into mechanical vibrations in the headphones' drivers, which then produce sound waves that reach our ears.
The useful energy from an electric drill is the mechanical energy it provides to drive the rotation of the drill bit, allowing the user to bore holes or drive screws. The electrical energy is converted into mechanical energy to perform work.

Lost energy refers to energy that is dissipated or wasted during a process, often in the form of heat, sound, or other non-useful forms of energy. This energy cannot be recovered or utilized for useful work.
The reason the useful output energy is always less than the input energy is due to inefficiencies in the energy conversion process. Some energy is always lost as heat, sound, or other forms of energy during conversion, reducing the amount of energy available for useful work. This decrease in useful output energy is described by the concept of energy conservation and the second law of thermodynamics.
In an electric heater, the useful energy is the heat generated for warming the room, while the wasted energy is the heat lost through the surroundings. In a television, the useful energy is the light and sound produced for viewing and listening, while wasted energy can come in the form of heat generated by the device. In an electric kettle, the useful energy is the heat used to boil water, while wasted energy can be heat lost through the kettle's exterior. In headphones, the useful energy is the sound produced for listening, while any energy lost through heat or vibration could be considered wasted.
