Preliminary measurements of the sensitivity of the vibrissae of Harbour seals ( Phoca vitulina) to low frequency vibrations
The sensitivity of the vibrissae of three Harbour seals ( Phoca vitulina ) to vibrations ranging between 50 and 1000 Hz was estimated using standard psychophysical techniques. Their vibrissae are relatively insensitive at the lower frequencies tested, however, vibrations which displaced the animal...
