The decibel level for a normal conversation is about db SPL.

With a code,stimulus frequency is represented by a match between the frequencies of the incoming sound and the timing of action potentials in auditory fibers.

True or False: Any sound source (loudspeaker,human voice,etc. )projects molecules outward,and the sound is heard when those molecules reach a listener's ears.
