There was also a rise in the range of 25 to 42 Hz.
Overall and local count rates lie in the several 10000 Hz range.
The shark can sense frequencies in the range of 25 to 50 Hz.
The 4038's frequency response is flat, with a range of approximately 30-15,000 Hz.
Sharks can sense frequencies in the range of 25 to 50 Hz through their lateral line.
Generating extremely low frequency waves in the 0.1 Hz range.
Bilateral sensorineural hearing loss in the 2000 to 8000 Hz range.
Inaudible sound waves can be felt by humans through physical body vibration in the range of 4 to 16 Hz.
For countries where power transmission is at 50Hz, the filter would have a 49-51 Hz range.
Acousto-magnetic systems use less power but their signals are pulsed in the 100 Hz range.
