The maximum sensitivity to sound for humans occurs primarily in the range of 1000 to 5000 cycles per second (cps), or hertz (Hz). Within this frequency range, human ears are particularly adept at detecting sounds, which is why many everyday sounds, such as speech and environmental noises, fall into this spectrum.

This heightened sensitivity during this range is linked to the anatomy of the human ear and the way it processes sound. The eardrum and the structures within the cochlea of the inner ear resonate best with frequencies in this range, allowing for clearer sound perception. As frequencies rise beyond 5000 cps, the sensitivity generally decreases, leading to diminished auditory perception of those sounds.

Understanding this aspect of human hearing is crucial in environmental health, especially when assessing noise pollution and its potential impacts on public health and well-being. It highlights why certain sounds, particularly in the specified range, might be more disturbing or harmful in terms of their physiological effects on individuals.
