Cats have one of the broadest ranges of hearing among mammals. Humans and cats have a similar range of hearing on the low end of the scale, but cats can hear much higher-pitched sounds, up to 64 kHz, which is 1.6 octaves above the range of a human, and 1 octave above the range of a dog. When listening for something, a cat's ears will swivel in that direction; a cat's ear flaps (pinnae) … WebElectromagnetic hypersensitivity (EHS), known in the past as "Microwave syndrome", is a clinical syndrome characterized by the presence of a wide spectrum of non-specific … WebAs we get lower on the spectrum, heading toward 20 Hz, we become less and less sensitive to SPL levels. We actually feel these sub-bass frequencies (20 Hz – 60 Hz) more than we hear them. On the higher end of the spectrum, we slowly lose sensitivity as we get older and repeatedly damage our hearing. problematiche in africa

For rats, however, the threshold is more like 24dB. That means that a 20dB sound at 1,000Hz would be easily audible to you but would be entirely inaudible to the rodent.

The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. [9] Individual hearing range varies according to the general condition of a human's ears and nervous system.
