Abstract The contribution of the ossicles (middle-ear bones) to auditory perception of microwaves
was evaluated by the brain-stem evoked response (BER). Amplitude and latency
of BERs were recorded from guinea pigs that were
stimulated at various intensities by acoustic pulses coupled to the auditory
canal or via bone conduction, and by microwave pulses. Blocking of the
external ear, middle-ear damping, and middle-ear destruction produced little
change in the BERs that were elicited by microwave
pulses. Results indicate that activity in the central auditory pathway as
induced by pulsed microwaves only requires stimulation of the cochlea.
Conduction of pressure waves through the bones of the calvarium
appears to be the mechanism responsible in perception of pulsed microwaves. |
