Auditory processing begins when sound waves reach the outer part of the ear, called the pinna. The sound waves are channeled down the auditory canal until they reach the tympanic membrane (or ear drum). From here, they travel along the ossicles to the fluid-filled cochlea. Inside the cochlea, hair cells are stimulated along the basilar membrane. When stimulated, these produce a neural impulse that travels from the auditory nerve to the thalamus to be processed. The process of converting the sound waves into a neural impulse is called transduction. A soft sound would have a - high frequency low frequency great amplitude small amplitude
