Sound

Sound is a mechanical vibration that propagates as an acoustic wave through a medium, such as air, water, or solid matter. The sound wave is created when an object vibrates and disturbances are transmitted through the medium. The disturbance causes pressure variations in the medium, which propagate in all directions at a speed determined by the medium's properties. The human ear is sensitive to sound waves within a frequency range of approximately 20 to 20,000 Hz. The perceived sound quality and pitch depend on the frequency and amplitude of the sound wave. The human voice typically falls within the range of 85 to 1800 Hz. Sound waves can be captured, amplified, modified, and reproduced using various technologies, such as microphones, loudspeakers, and audio processing software. Sound has numerous applications in communication, entertainment, and scientific research. This is a mind map about sound. The map includes Physical Nature, Perception of Sound, Uses of Sound, and Sound Pollution. Each main branch has a detailed description of multi-level sub branches. Suitable for people interested in sound.
