Answer:
Tiny bones located in the middle ear
Step-by-step explanation:
The smallest bones in the human body are the irregularly shapes auditory ossicles of the malleus, incus, and stapes. In conjunction with the rest of the anatomical structures of the middle ear, these bones help for the transformation of sound waves to vibration signals that can be transmitted to the inner ear for interpretation. The malleus receives vibrations to transmit to the incus, which then transmits them to the stapes, which then causes a vibration through the oval window's membrane for propagation of this sound through the inner ear. The stapes bones looks like a staple; the incus resembles a horn of sorts or a conch shell, possibly an anvil as its name suggests; and the malleus looks like a club, hammer, or mallet.
The cone cells in the retina are the long-wavelength (L), medium-wavelength (M), and short-wavelength (S) cones, the majority of which are long types in the human eye. These cones allow for color vision.
Words often used by audiologists in testing for hearing difficulties simple words like "bar," "clove," "pants," "knees," etc. that can be easily repeated back to them in order to determine if the patient is struggling. Malleus, incus, and stapes are all Latin words that could possibly sound like English words ("mallet, ink, staples"), not to mention uncommon in daily vernacular, so they would likely be avoided.
The type of sound most people can detect is called audible sound. Inaudible is quite the opposite, undetectable by most people (usually frequencies outside of 20Hz and 20 KHz).
