the Cochlea
The cochlea.
the middle ear
The electrical signal travels down the axon to the axon terminals where it tells the vesicles to release the neurotransmitters (which are chemical signals consisting of hormones like dopamine and adrenaline) into the synaptic cleft which travel to the receptors of the receiving cell which releases the second messengers which are chemical signals that propagate an electrical impulse in the receiving cell. Oh biomed. How we love you.
As part of the external ear, the auricle or pinna acts like a horn to capture sound waves. They are then diverted or collected into the auditory canal. At the end of the canal is the tympanic membrane (eardrum) which changes the sound into vibrations to be transmitted further into the ear.
Optic nerve
The cochlea.
The tranducer/microphone converts the vibrations of the waves into electrical audio signals, the vibrations cause a diaphragm inside the transducer to vibrate which in turns create pulses of current that can be interpreted later as the recorded audio.
It is called the RETINA
The peripheral nervous system.
None - except as an artifact. The nerve cells (auditory nerve) carry the signal chemically and produce electrical signals as a side effect of ion flows. Your brain ignores the electrical signal but responds to neuro-transmitters released by the nerve cells at synapses.
the cochlea
The malleus is a tiny bone in the middle ear that transmits sound vibrations from the eardrum to the incus (another middle ear bone). This process helps amplify and transfer sound energy to the inner ear, where it is converted into electrical signals that the brain can interpret as sound.
The eye and ear are parts of the sensory system. The eye is responsible for detecting light and creating visual signals that the brain interprets, whereas the ear is responsible for detecting sound vibrations and translating them into auditory signals.

The types of tissue that generate electrical signals would have to be examined on a case-by-case basis. There are a number of creatures that are bioluminescent, that generate light (which is electromagnetic radiation). And there are electric eels and electric catfish that generate a "pulse" of electrical energy. Additionally, many organisms have nervous systems that generate electrical signals as part of their nerve function. The variety of tissues that generate electrical signals varies widely depending on what kind of electricity or electrical signal is being generated. These tissues can generally be studied only individually, as the mechanism of electrical generation by one may be significantly different than that of another.
