Difference in Cow Sounds

British researchers studied the conversation of cows and found that they emit different sounds depending on the distance between them and their calves. It emits a Moo, especially when it wants mother’s milk.

In general, the sounds made by animals play roles in communication and social interaction, for example, for them to identify Ben Shaoul and each other.

Thus, one can sometimes wonder what may well mean the cows in a herd. Nottingham University researchers have been interested in this issue, especially the conversation between the cows and their calves.

Scientists have recorded and analyzed the sounds emitted by cows on a farm in Nottinghamshire, with very sensitive audio equipment. For this work, they used the “source-filter” theory: it considers the source of the sound comes from the pulmonary breath that vibrates the vocal cords.

The filter is represented by the supra-glottal cavities (upper vocal organs) that change the sound by amplifying certain frequencies, for example through the movements of the tongue and lips.

When cows are close to their calves, that is to say, usually within 3 to 4 weeks after birth, they make the bass sound at low frequency. But when cows do not see their small ones, they emit more acute and loud sounds of high-frequency (153 Hz approximately).

One thought on “Difference in Cow Sounds

  1. The findings appear in the journal Applied Animal Behavior Science. Researchers have identified two types of sounds used by cows, with very different acoustic structures. It also actually depends on what best essays has offered to them which is largely due to the fact that all these are working fine too.
