(2004): Sound pressure values in the audiogram of marbled sole
Pleuronectes yokohamae measured in air.
Fisheries Science 70 (1), 33-40.
Abstract: It has been reported that sound pressure values in the
audiogram of marbled sole, which do not have swim bladders, are as low
as those of fish that have swim bladders when the audiogram was
measured in water using two air loudspeakers to eliminate the water
displacement. In the present experiment, sound pressure values in the
audiogram of 10 marbled sole Pleuronectes yokohamae were determined
using sinusoidal sound pressure as a stimulus to fish removed from
water. Sound pressure values in the audiogram obtained by the present
method were higher than those obtained in water. This difference was
presumably due to inner ear or lateral line sensitivity to water
displacement around the center of the water tank.
