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.
The red outlines the highest or loudest part of the sound. The image shows the 3 seconds of the meadowlarkâs song. We see that between 1,744 and 6,000 Hz (the frequency) is the major part of the sound whereas at 2.2 seconds into the sample it dips lower, too. Consider a spectral analysis a voice print. Letâs let the same species be the judge. Elephants will judge elephants and lions will judge lions and so forth. If the judge where only those of the same species, then the winner would be the elephant. I would include a sound clip of the elephant, but humans cannot hear the sound they make, due to the low frequency.
