Color.
(British eyes observe changes in colour.)
speech vary s continuously in frequency and amplitude a carrier wave matches the changes in the sound wave.
-- The highest frequency of sound audible to the human ear is of the order of 20,000 Hz.-- The lowest frequency of light visible to the human eye is of the order of 375,000,000,000,000 Hz.
The frequency range for human audible sound is 20 Hz to 20,000 Hz.
The mass(kg) of a human does not change, but the weight(N) of a human does. If gravity gets stronger, you get squashed(!), but if it gets lighter, you float around!
Humans can hear sounds of 20 to 20,000 Hz. Hearing is best in the middle part of this range. However, the acuity varies between individuals and changes with age so that there is no specific frequency at which humans hear best.
These are the substations which can have the capabality to change Frequency which it gets from the generators, human interventions neccessary to accomplish this task.

yes, it usually changes color as you get older
no You might say that, even though nobody else ever does. A change in the frequency of sound is perceived as a different 'pitch'. A change in the frequency of light is perceived as a different 'color'. In each case, even a small change in frequency is easily perceptible to the human sensory system. Who cares what word you use to describe it !

The human nose can recognize 10,000 scents
It's due to evolution, and what you call it a Human evolution or anthropogeny. (It's one of my opinion ,giving more slope towards Human" "Time changes , people also changes."
