Sound
A type of mechanical wave that travels through air, water, or solid materials, perceived by the human ear as vibrations.
Cochlea
A spiral-shaped organ in the inner ear that converts sound vibrations into neural signals.
Pinna
The outer ear structure that collects sound waves and directs them into the ear canal.
Amplitude
The maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound, amplitude determines the loudness or intensity of the sound wave.
Oscillioscope
An electronic device used to display and analyze the waveform of electronic signals, often used in audio and sound engineering to visualize sound waves.
Frequency
The number of cycles of a sound wave that occur in one second, measured in hertz (Hz). Frequency determines the pitch of the sound.
Hertz
A unit of frequency equal to one cycle per second, often used to measure sound wave frequencies and determine pitch.
Longitudinal wave
A type of wave in which the displacement of the medium is parallel to the direction of the wave's propagation, commonly seen in sound waves.
Middle ear
The part of the ear located between the outer ear and the inner ear, containing the eardrum and three small bones (ossicles) that transmit sound vibrations to the inner ear.
Eardrum
The thin membrane that vibrates in response to sound waves, transmitting sound to the ossicles in the middle ear.
Auditory nerve
The nerve that carries auditory information from the cochlea of the inner ear to the brain, allowing for the perception of sound.
Crest
The highest point of a wave, where the amplitude is at its maximum.
Trough
The lowest point of a wave, where the amplitude is at its minimum.
Vibrations
These are oscillations that travel through a medium, producing sound waves that can be perceived by the auditory system.
Ears
The organs responsible for detecting sound waves and converting them into electrical signals for the brain to interpret.
Vocal cords
Structures in the larynx that vibrate to produce sound when air is expelled from the lungs.
Tuning fork
A device that vibrates at a specific frequency when struck, producing a clear musical tone used for tuning instruments and testing hearing.
Vacuum
A space devoid of matter, where the pressure is significantly lower than atmospheric pressure. It is often used in scientific experiments and applications.
Compression
The process of reducing the volume of a gas or substance, increasing its pressure by applying force or external pressure.
Rarefaction
The process of reducing the density of a gas or substance, resulting in a decrease in pressure, often occurring alongside compression.
