Sound waves cause the tympanic membrane (eardrum) to vibrate, which in turn causes the malleus (hammer) to vibrate. This vibration is transmitted through the ossicles in the middle ear, ultimately leading to movement of the stapes against the oval window of the cochlea.
The malleus is the first of the three auditory ossicles (little bones) of the middle ear. The next on in line is the incus (anvil).tympanic side = malleus or hammermiddle = incus or anviloval window side = stapes or stirrup
Mechanical Waves
Thermal energy causes particles to vibrate. When thermal energy is transferred to an object, its particles gain kinetic energy, causing them to move and vibrate.
Glass bends when heated because the heat causes the molecules in the glass to vibrate more rapidly, changing its structure. This change in structure leads to expansion, causing the glass to soften and bend. This effect is known as thermal expansion.
When a source of energy causes a medium to vibrate, it creates sound waves. Sound waves are mechanical waves that travel through a medium by causing the particles of the medium to vibrate and transfer energy in the form of sound.
The eardrum (tympanic membrane) vibrates in response to sound waves, which in turn causes the malleus (hammer) bone to vibrate. The malleus is connected to the eardrum and transfers these vibrations to the other ossicles in the middle ear, ultimately transmitting the sound to the inner ear for processing.
The auditory bones vibrate in the order of malleus (hammer), incus (anvil), and stapes (stirrup) when sound waves are transmitted through the middle ear.
Sound waves cause the Tympanic Membrane (eardrum) to vibrate, which in turn causes the Malleus (hammer) to transmit those vibrations to the next tiny bone in the ear, called the Incus (anvil). The Incus, in turn, transmits those vibrations to the third small bone in the ear, called the Stapes (stirrup). The Stapes then transmits the vibrations to the membrane of the inner ear, where they can be communicated to the brain for processing and interpretation (hearing).

The sound waves, coming through the auditory canal, strike the tympanic membrane (eardrum).The eardrum vibrates because of the soundwaves.This vibration is picked up by the ossicles and transmitted through the middle ear to the oval window.Therefore it is the soundwaves causing the eardrum to vibrate that ultimately makes the ossicles vibrate.
Heat energy from the source causes the particles to oscillate (vibrate) this chains and causes neighbouring particles to vibrate.

they vibrate..
The pathway consists of the tympanic membrane, ossicles (malleus, incus, stapes), oval window, cochlea, and cochlear fluids (perilymph and endolymph). Sound waves cause the tympanic membrane and ossicles to vibrate, transmitting the vibrations to the oval window and cochlear fluids, which in turn stimulate the hair cells of the spiral organ of Corti.
vibrate or oscillate. This vibration is then transferred through the medium, causing particles in the medium to also vibrate. This transfer of energy produces the mechanical wave.
