Ear wiggling is movement of the external ear using the three muscles which are attached to it forward, above, and behind.Some mammals such as cows have good control of these muscles, which they use to twitch and orient their ears, but humans usually find this difficult.
As humans grew more proficient with visual and vocal systems, ... and are important for ear wiggling,” study first author Andreas Schröer of Saarland University in Germany, said.
The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing, shouting, or thunder.
One consequence of the configuration of the outer ear is selectively to boost the sound pressure 30- to 100-fold for frequencies around 3 kHz. This amplification makes humans most sensitive to frequencies in this range—and also explains why they are particularly prone to acoustical injury and hearing loss near this frequency.
Sad fact: Unfortunately, wiggling your own ears doesn't offer the same auditory upgrade. Dog ear canals are also longer, wider, more flexible, and more cone-shaped than those of humans.
