Oh that's sneaky, I'll have to pay more attention to that stuff in the future.TSny said:Note that the sound spreads over a hemisphere (not a sphere).
Sound waves are a type of mechanical wave that is created by vibrations or disturbances in a medium, such as air or water. These vibrations travel through the medium, carrying energy and creating changes in air pressure, which we perceive as sound.
The energy of sound waves is measured in watts, which is a unit of power. Specifically, it is measured as energy per second, or joules per second, as sound waves carry energy through the medium they travel in.
The energy of sound waves can be affected by several factors, including the amplitude of the wave (which determines its loudness), the frequency of the wave (which determines its pitch), and the density and temperature of the medium through which the wave is traveling.
The energy of sound waves directly impacts our perception of sound. For example, higher energy waves with larger amplitudes will sound louder to us, while higher frequency waves with more energy will sound higher pitched. The energy of sound waves also determines how far they can travel before dissipating and becoming too faint for us to hear.
Understanding sound wave energy is important in many fields, including acoustics, music, and engineering. It allows us to design and create better sound systems, improve the quality of audio recordings, and develop technologies like noise-cancelling headphones. In medicine, sound wave energy is also used in ultrasound imaging to visualize internal structures of the body.
