The human ear responds more to frequencies between 500 Hz and 8 kHz and is less sensitive to very low-pitch or high-pitch noises. The frequency weightings used in sound level meters are often related to the response of the human ear, to ensure that the meter is measuring pretty much what you actually hear. It is extremely important that sound level measurements are made using the correct frequency weighting - usually A-weighting.
Itâs a game-changing technology. Hereâs how it works. CHIRP is a frequency-modulated sonar pulse that overcomes the limitations of current technology, which relies on a single-frequency pulse bouncing off fish and the bottom.Traditional sonar operates on either 50 kHz, for deepwater fish finding, or 200 kHz, in shallower water.tâs a game-changing technology.
